At Statecraft, we are building an AI workforce to help automate the US government. Currently our government is operated almost entirely by consultants who outnumber public servants 3:1 and institutionalize inefficiency so they can bill more hours. This only leads to agencies struggling to meet their missions, overworked and underpaid public servants, and overburdened taxpayers.
Most of what these consultants do is easily automatable: data entry, basic spreadsheet work, filling out paperwork, etc.; we do this with AI and save taxpayers ~80% on average while completing the work ~10x faster with 2-3x less errors.
We're a small, lean, mission-driven team and hiring Forward Deployed Engineers to build use cases and integrate deeply with agency customers. You'll be working with critical systems, massive surface area and national impact.
* This position requires U.S. citizenship and the ability to obtain/maintain a security clearance.
Our mission: make handling memory, state, and context for AI agents outside the cloud as simple as it is in the cloud. Today it isn't close. An agent without data is inert, and outside the cloud, data is duct tape.
An agent in the field needs data that is verifiable, auditable, concurrent, collaborative, and permissioned. No single system gives you all five. SQLite gives you local storage and nothing else. Every other database assumes the cloud is there to provide the rest.
We're building the data layer agents actually run on: local-first, syncs peer to peer, every write verifiable, every read auditable, no cloud required. The stack is open source: https://github.com/sourcenetwork/defradb. We think it's the best memory an agent can have, bar none.
We’re growing fast and are looking to fill the following positions:
Greenzie | Robotics Software Engineer (Early Career + Experienced) | Atlanta, GA | ONSITE/HYBRID | Full-time | https://greenzie.applytojob.com/apply
Greenzie builds the autonomy software that runs on commercial mowers. We don't sell the iron — Wright, Mean Green, Bobcat, and Greenworks Commercial do, with our stack on them. Mission is to free humans from repetitive outdoor labor. The software is on hundreds of machines in the field today.
We're hiring roboticists who want production robots doing real outdoor work, not lab demos. C++, Python, ROS/ROS2. You will own (or learn) a subsystem, debug messy field data, and ship to machines that mow for a living.
When you look at the headers of major websites, you’ll see us. If it has to be performant, secure, scaled worldwide, and always-on, it uses Fastly.
We're a global edge cloud platform for performance and security, emphasizing open standards, sustainable engineering, and resilience-by-design.
We're hiring across compute, security, platform engineering, network and edge protocols, release engineering, network architecture, client services engineering, and more.
Onsite preferred, but remote candidates with a strong fit are welcome!
Rather than building walled gardens, we co-founded the Bytecode Alliance, heavily upstream our work to open standards, actively author IETF drafts, and power the global infrastructure for open-source Python, Rust, Ruby, OpenStreetMap, and much more.
* The Stack: Rust, C/C++, Go, Javascript, Typescript, WebAssembly (Wasm/WASI), Wasmtime, Cranelift, eBPF/XDP, QUIC, HTTP, TLS, TCP, Varnish/VCL, Linux kernel internals, distributed systems, professional services.
* Apply: https://www.fastly.com/about/careers
Yeah The Who's hiring format isn't a perfect fit for how we have it structured. In general, engineering can hire remote first if there's a good fit, and we have local entities or EOR processes for every EU country (to the best of my understanding)
We make robots that autonomously construct buildings, starting with bricklaying.
There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run.
We're looking for experienced software engineers for many roles. You can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
We're rapidly scaling up operations - we'll be building in the UK soon - and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!
National Association of Realtors | Chicago or Washington DC - ONSITE | Data Analyst | Full Time
We want Python + Pandas, SQL, statistics, data visualization and some AI; the usual data science stack. Job is in-depth data analysis across multiple data sets - the challenges change weekly. We're using Cursor for data science and AI is permeating all our analysis work - we're transforming from traditional data science to being AI-forward.
We're building a system that represents domain knowledge as modular probabilistic models — making analysis rigorous and transparent. Users can connect these models flexibly into larger structures. The system enforces consistency across them, and propagates uncertainty through each step. Our first applications are in finance and scientific research, with use cases ranging from equity valuation and distress monitoring, to particle physics.
We're hiring for the following openings:
* Engineering Program Lead
* Backend Software Engineer
* Quantitative Modelling Engineer
* Bayesian Software Engineer
* Program Synthesis Engineer
* Analytic Learning Algorithm Researcher
* Product Managers and Business Development
* Domain Experts - Valuation, Quantitative Default-Probability, or Interest Rate Prediction Models: to collaborate on use cases, from opportunity validation through production
We’ve recently released a series of recordings from one of our quarterly team retreats, to share a look into how we work, and some of the technical problems we’re solving. A few team members sat down and talked through these topics, unscripted, and real. If you consider applying to join us, they offer a glimpse into our culture, and what working with us is really like.

Wikimedia Foundation | Lead Product Manager, Security | REMOTE (US + 18 countries) | Full-time
I lead the security and safety team for Wikipedia, at the Wikimedia Foundation. I’m hiring a product manager to lead our security roadmap and steer the priorities of our security engineering team.
It’s a high-pace, shipping-heavy time for the whole project right now, as we are dedicating ourselves to surviving all the ways AI is messing with us and the internet, and getting to the other side of it. I joined myself about a year ago, and have found it to be a great time and place to swing big and surprise people.
This is a PM role and PM background is certainly helpful, but it’s not strictly required (everyone has the first PM job at some point). A technical background and security expertise are a must for this role, so we’re also open to people in engineering roles, who have demonstrated PM-relevant skills and are interested in making a pivot.
I‘ve been considering applying at WikiMedia for a while now, but [my country] is not in the listed countries. Is there a chance you‘ll expand this list in the future?
Ah, that is too bad. It's certainly always possible the countries list could expand in future, but it's not something I have insight into and unfortunately can't give you too much to go on.
At Quobyte we are working on a highly scalable and fault-tolerant software storage system built around a parallel file system core. Our customers use us for large scale AI and HPC clusters in the enterprise and research, k8s and OpenStack infrastructures, and as a scalable backend for SaaS products. There are Quobyte clusters which span tens of thousands of machines and slurp 100s of GB/s!
Under the hood, we have built a full-stack fault-tolerant parallel file system, with everything from kernel development over our own replicated database system design to distributed algorithms (Paxos!) and performance. In short: lots of real-world challenging and fun problems!
We work as a highly efficient engineering team, ship frequently, do code reviews, and have lots of unit and integration testing. If you’re passionate about systems, we might be the right place for you!

We're the system of record for the Canadian vehicle: raw automotive data turned into facts that can be checked. Our open-source VIN decoder sits underneath a government vehicle registry.
Some of what's interesting:
- A government registry, a manufacturer's own filing, a listing site and an insurance record will describe the same truck four different ways, and nothing in any of those files says they're the same truck. Reconciling that, for every vehicle in the country, in a way that holds up when a regulator asks how you know, is most of the data work.
- Seventeen characters on a door frame encode manufacturer, plant, model year and build attributes — badly, inconsistently, and differently per manufacturer. Public reference data covers some of it. The rest gets worked out from filings, recall documents, and patterns inferred across millions of vehicles.
- We read vehicles directly over OBD-II now. Forty modules answered on a recent Hyundai, each reporting its own part number and installed software version. Nothing downstream of the VIN moves when a module is reflashed, so no registration, history report or dealer system knows what software is actually in a car.
PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of future technologies, energy and climate, health innovation and fundamentals of nature. By performing fundamental and applied research, we work on sustainable solutions for major challenges for society, science and economy.

We're a small IT consulting firm working in federal and other regulated environments. We're building a reusable Terraform module catalog: versioned, tested, documented modules published to a registry that other teams consume, across cloud, container, and virtualization environments. Module and platform engineering, not one-off deployments.
You'd own the standards: module interfaces, validation, testing, releases, deprecation. Small team, no layers, and real influence over how we build. Growing, with room to move into broader platform ownership or technical leadership.
Looking for someone who has built and maintained a shared module library other teams actually used. Semantic versioning, automated testing, input validation, policy compliance checks, CI gates. Production experience with AWS, Azure, GCP, or OCI.
Multiple positions. US citizenship required (federal contract). No visa sponsorship.

Trustworthy Technology | Earth | Part Time | REMOTE | Vision, Marketing, and/or Design
Hi, we are a small group trying to bring the "trustworthy" feature back to tech. Curating and building a FOSS+ toolset, storefront, and eventually online service—all to support freedom, privacy, and informed consent—on device and on the net.
First off, you'll notice that you've not heard about this project before. Next, the message is a bit scattered, and the "programmer art," while arguably not horrible isn't winning any awards either, haha.
That's where you come in.
You are one of the few folks who really cares about this stuff, and also a graphic/product designer, or perhaps a digital marketer, communicator or "people whisperer." (Being in the EU would be helpful as well, to work from the digital sovereignty angle, though not required.)
Some of us are unemployed and currently donating our time. Maybe you are too, or retired/cashed-out and bored. Consider this another FOSS-like project. We hope the store/service will make money, but we're not there yet.
LatchBio | Member of Technical Staff (infra, ML infra, systems, platform, full stack) | ONSITE San Francisco | Full Time

We are a group of engineers, scientists, and operations specialists who are driven by improving capabilities and interpretability. Some of our work is showcased on benchmarks.bio.
I run our engineering team and will read and respond to all emails sent to aidan@latch.bio. You can also apply here via a more structured form: https://jobs.ashbyhq.com/LatchBio.
Great Question is the best way to understand your customers - whether it's mining what they've already told you, or generating new research via interviews, surveys and prototype tests. We're 2nd time founders, closed our Series A last year, with customers from Canva & Brex to Intuit & Amazon.
We're hiring product engineers to help us push the envelope on what's possible in AI engineering practices, while helping our customers bake customer insight into every product release.
You'll do well here if you have a strong sense of what makes a quality product, you're AI native, and you solve the problem of ambiguity with getting closer to customers.
A bit cryptic, but their legacy product is kinda linked, which points to a URL with a single, different letter where this should be pointing: https://greatquestion.co/careers
Pagelove collapses the modern web stack into its simplest form: no databases, no APIs, no application servers. Just HTML that works like an app, scales like a CDN, and is AI-native by design.
The page becomes the application, API and persisted state. Humans and machines can read and update the same surface directly using CSS selectors over HTTP, rather than through separate HTML and API/MCP interfaces. With Pagelove, AI can finally build web applications without having to deal with the complexity of the full stack.
We’re seed-stage and well-funded, hiring our first non-founder engineer. The codebase is Rust, with work including distributed storage, HTTP caching/ETags, CRDTs, parser/DOM performance, CI and production infrastructure.
Our development process is heavily agentic: Claude Code and Codex do substantial implementation work, with humans focused on architecture, review and the hard problems.
We're building out our NYC-based API platform team as our API-based business rapidly grows. We're a European -based company, so you'll enjoy the best of both worlds with competitive compensation, 30 days of PTO from day one (your manager, me, will make sure you use them all) "work from anywhere" days, addtional compensation for on-call shifts (including additional time-off if you actually have to do something after hours)

We are a self-funded independent AI research lab in Zurich. Currently we explore ARC-AGI3, LLM/RL reasoning, and quant. We recently started a new LLM post-training and pre-training effort, led by some ex-engineers from the swissAI Apertus team. We also like to do some Kaggle on the side, our team includes the top #3 and #12 globally.
Our overall roadmap is to catch up with LLM capabilities, own the full stack, and use it to do our own independent research, pushing efficiency and looking for new paradigms. We expect our new cluster (2x NVL GB300) to be up by the end of the month.
Long term we want to switch to AI alignment/safety research as I believe this is all that matters when AI capability is high enough.
We look for people who are driven, who believe it's possible to make significant contributions to both AI capabilities and safety, and with previous experience pre-training and post-training LLMs and related infra.

Biobase has grand ambitions. We broker biospecimens, whole slide images, and the clinical metadata attached to them, on a supply-chain backbone that we're steadily automating. We’re building healthcare-data-focused agents on top of the datasets that we’re assembling, too.
We'd rather build the thing that removes the work than throw people at it. Two roles, one team, both reporting to the CPO:
Senior Technical Product Engineer ($150–230k + meaningful equity).
The product team's technical interface. Architecture decisions and code review on the platform (Python/FastAPI, TypeScript/React, Postgres, Azure); the data pipeline and informatics that take specimen, slide, and clinical data in from suppliers and labs; and product ownership of the internal platform that builds our agents (permissions, evals, cost control, guardrails for sensitive data). You've been the reviewer of record somewhere, you've operated what you shipped, and you think in business problems before tickets.
Technical Product Engineer, early career ($90–170k + equity).
Same territory at an earlier stage: the platform, the data pipeline and informatics, and the agents we run against our own operations — with a senior product engineer and our lead engineer reviewing your work and pairing when it helps. Open on background – self-taught, bootcamp, degree, research lab, a career you're leaving – selective on the bar. You've built something and someone else used it.
We build with Claude Code every day and expect you to become both fluent with it and skeptical of it. No ticket queue, no spec handed to you. Comp is salary + equity combos you choose between.
To apply: email jobs@biobase.ai with something you built that eliminated manual work and what happened after it shipped. Links over resumes, no cover letter.

We are a team of 25 with experience at companies such as Google, Meta, Stack Overflow, Rippling, Snowflake, Confluent and Kaggle.
Everyone in health AI is chasing scribes and diagnostics. Almost no one is building the longitudinal data layer that captures what actually happens to patients over time. That is the real moat, and we are building it for eye care.
Deya sits between doctor and patient, capturing symptoms, treatments, outcomes and ocular images over time. Clinician-led, piloting with eye doctors, and we hold the largest dataset of eye images captured on smartphones. We build with AI tools daily.
Three roles, all high ownership:
Software Engineer (AI x Healthcare)
- Product and infra from 0 to 1. Next.js, backend, cloud, agentic workflows, longitudinal clinical data.
Mobile Engineer (React Native, Swift, Kotlin)
- A modern phone is already a clinical instrument and almost none of it has been pointed at eye care. Own the app and its UX end to end.
AI Engineer (Computer Vision + LLMs)
- Own the vision pipeline turning phone photos into clinical signal, plus the LLM systems reasoning over patient history.
We have a proprietary clinical dataset and because we control capture, you can improve the data itself rather than model around its limits. Optometrists and ophthalmologists in-house to define ground truth and validate the work. Competitive salary plus equity.
GovStar is hiring 5 engineers to help build secure, production-grade AI and advanced analytics capabilities supporting U.S. national security missions.

Vitalize | Senior Product Manager or Staff Product Manager | San Francisco (hybrid)
What we do:
Hospitals run critical operations (staffing, labor planning, and capacity) on spreadsheets, phone calls, and gut instinct. Labor is the biggest cost and hardest operational problem, and it’s still largely manual. Vitalize is building the operating system for hospital labor (and ultimately capacity): we forecast demand from real hospital data (e.g., ADT + historical patterns + acuity) and translate that into concrete staffing decisions: next month’s schedule and the next shift.
Traction:
- ~$37M raised
- Launched 2024; ~$13M committed ARR across 10+ health systems
- Live in 20+ hospitals and growing quickly
The role:
We're hiring a PM to own the product experience that takes a hospital from signed contract to successfully using Vitalize in production. Getting there is complex: every health system has its own HRIS, scheduling workflows, union rules, and technical environment. This team builds the custom integrations and internal tooling that make those deployments faster, more repeatable, and less manual as we scale.
We're looking for a PM who...
- Led messy third-party enterprise integrations deep enough to make real technical calls with eng
- Has built internal tooling with an internal team as the customer
- Prioritized a roadmap under live GTM pressure and held the line when the loudest deal wasn't the right build
- Startup experience, where the system you were building didn't exist yet

• High level of product ownership with tight feedback loops: the products you build are shipped quickly and get used by real customers immediately. Our latest hire built our entire CLI product from 0 -> 1, and it was used in production by customers the day it shipped.
We are growing the team to keep up with demand for new features that our customers are asking us for, while also preparing for launch. We're looking for someone that will make us better. We’re just getting started, and want you to bring your opinions, expertise, and experience to the table (not just execute on the ideas we already have).
This Dot Labs is an AI-native software engineering consultancy with a remote-first, global team. We help companies design, build, modernize, and scale production software.
You will work directly with clients and collaborate with experienced engineers across time zones. We value strong communication, independent ownership, technical excellence, and active participation in the developer community.

Loft Orbital | Senior Cloud Infrastructure Engineer (SRE) | Golden, CO or San Francisco, CA | $180k–$240k + equity | https://loftorbital.com
Loft builds and operates shareable satellites so customers can fly a payload without building a spacecraft. We integrate, launch, and operate the mission end to end: Earth observation, IoT, on-orbit AI, national security. 30+ missions flown since 2017, fleet on track for 30 satellites by 2027, offices in SF, Golden, and Toulouse.
Our Cloud Infrastructure team runs the ground segment that talks to the fleet. This is an SRE role with a twist: we apply DevOps practices to spacecraft control (we call it SatDevOps), and we'll train you to operate the satellites.
What you'd own:
- Hybrid cloud infra on GCP + Kubernetes: provisioning (IaC), CI/CD, GitOps (ArgoCD/Flux)
- The observability stack (Grafana, Prometheus, Loki, tracing) across ground and flight systems
- Reliability: RCAs, fault tolerance, performance tuning, long-term fixes over patches
- Software-defined networking between ground stations, cloud, and mission ops
- Developer experience: tooling and environments for the flight software and ops teams
Looking for: strong public cloud (ideally GCP), deep Kubernetes, one backend language (Go/Python/Rust/C++/Java), IaC + CI/CD in anger, and someone who can design HA systems and then run them. Nice to have: FinOps, security tooling, orchestration in resource-constrained environments.
Benefits: 100% company-paid medical/dental/vision for you and dependents, 401(k) + equity, flexible PTO + 12 holidays, 14/10 weeks paid parental leave, daily catered lunch, relocation assistance, and time with the team in France.
Snowflake | Forward Deployed Engineer, Product Manager | Menlo Park, CA | Warsaw, Poland | London, UK | ONSITE
I’m part of Snowflake’s Applied AI / Forward Deployed Engineering team, and we’re hiring for multiple roles on the team.
We work directly with strategic customers to design, build, deploy, and improve production AI systems on Snowflake. That includes LLM applications, RAG and agentic workflows, evaluation frameworks, guardrails, observability, and production iteration using Snowpark, Cortex, and Snowflake’s native AI capabilities.
For the FDE role, we’re looking for strong engineers who can build and ship customer-facing AI systems end to end, especially if you’ve worked on LLM apps and care deeply about evals and quality. For the Senior role, we’re looking for someone who can lead multi-engineer AI engagements, mentor other engineers, and still be hands-on in architecture and implementation. The roles are customer-facing and involve travel, including at least 25% onsite time with strategic customers.
If you like working in ambiguity, building real AI systems instead of demos, and partnering closely with customers to get things into production, these roles are a good fit.
Do you feel scared and alone when opening the AWS console? Do you wish you could just tell Claude to manage your infra, and it would just work? Do you dream of a future where software is abundant and developers and normies alike are free to build their wildest dreams?
We're Railway, and we think infrastructure can be better. We're working at the forefront distributed systems engineering, interface design, and agentic computing to bring about the infrastructure platform we've always wanted. So far we've built out a platform loved by 3M+ users and we're just getting started.
Fair warning! The problems are complex: racking and stacking servers, home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.
Noricum | Senior Backend Engineer, Payments, Ledger & Provable Fairness | REMOTE (2h overlap with US Pacific) | Contract to permanent | $120-160/hr | Start by 14 Sep
I'm the founder of Noricum where we build platforms – currently the money infrastructure, ledger, engine and payment rails behind a pre-launch wagering platform with a Steam skins economy. The games, a cashier and a bet ledger are built and live as a front end, with written specs for the server contract: ledger schema, refusal table, round lifecycle, every game's arithmetic. Processing and licensing are secured. The server does not exist. That is the job. You would own:
- A server-authoritative game engine - seeds, nonces, outcome computation
- A double-entry ledger where balance is derived and no client write can change it
- Server-side enforcement of every limit and refusal
- Payment rails idempotent under duplicated webhooks
- Seed custody and the provably-fair lifecycle
- An affiliate system with referral attribution and commission payouts
Must have shipped: a double-entry ledger or equivalent money system in production, a payment integration including webhook idempotency, auth and sessions you built and operated, and infrastructure you owned end to end. Provably-fair systems, settlement-side gaming or trading infra, or Steam trade automation all stand out.
Email michael@noricum.io with your start date and a few lines on the last money system you shipped - what it guaranteed, and how you knew it held.
ODK is an open-source platform used by thousands of organizations worldwide to collect billions of data points for disease surveillance, supply chain traceability, environmental monitoring, and more. It enables users to build powerful forms and reliably collect structured data, even in places with little or no Internet connectivity.
ODK has been actively developed for 18 years. We have a mix of self-hosted and SaaS users across many sectors. We're looking for a senior product manager who will own product discovery and prioritization across this diverse user base. To be successful, you'll need to find the common needs behind very different workflows and turn them into opinionated product improvements.
Because the team is small and the user base is large, this is a high-autonomy role where product decisions have an unusually direct impact. You should have substantial experience managing complex B2B or technical products. Experience with open source, self-hosted software, and small, fully remote teams is a plus.

Seven-plus years shipping, hands on code within the last year. Design and engineering sit in the same room here. There is no handoff.
Most people who apply like the words "founding engineer." We are looking for someone who has already started something of their own.
Ownership. You should own a piece of what you build here. We are not going to post a percentage, because the honest answer depends on what you end up carrying, and we would rather work that out with you than hand you a number that pretends to be precise. It is a conversation, it is flexible, and we intend it to be fair.
We are six people. Nothing you build goes through a committee before it ships. Nothing you break, you fix alone. We are a tight team today and we are looking to double it by the end of the year.
Please send your resume or GitHub, plus the most ambitious thing you have built mostly on your own. Rough work that worked beats polished that never shipped.
If this is not you but a name comes to mind, please pass it along. :)

We're building the intelligence layer for physical risk: digital twins of individual homes, run through physics-informed AI World Models, to see exactly how a specific property will perform in a wildfire or hurricane — traditional models only guess at the neighborhood level. That precision lets us do what insurers historically couldn't: measure how much a new roof, cleared vegetation, or better siding actually cuts risk, then price coverage accordingly, turning mitigation into a real financial incentive instead of just advice.
We've scaled to ~$10B in insured assets in just two states in under a year. The interesting problems: ML surrogates that run physics simulations 1,000x+ faster without losing accuracy, structure-level digital twins built from imagery and property data at scale, and systems that reason across risk, cost, and homeowner tradeoffs — we're hiring across engineering and applied science.
We are a RIA looking for an incredibly inquisitive person who enjoys rolling their sleeves up and diving into data. Technology is only part of the role. Working with stakeholders--and understanding what their pain points are--is more important than optimizing a query.
Help us build an AI-first engineering, manufacturing, and supply chain platform. What if you could ask AI: "how does this new turbine blade geometry affect our 42MW power requirements?" And actually get a meaningful answer? This is the platform that supports Superpower, Symphony, and Overture from design to deployment across multiple factories. If you love hard-tech, distributed systems, web apps, and building AI infrastructure at scale, please apply.
Also hiring for telemetry and engine design and analysis software roles.

Brilliant is building the world's first graphical AI tutor: a collection of interactive learning experiences that both the learner and their AI tutor can see and manipulate. In a world of cognitive offloading, Brilliant's AI gets people to actually think and solve hard problems.
We're hiring an interactive-focused engineer to craft the building blocks that power it. Each interactive exposes an API used by learning designers, our authoring agents, and the tutor itself. And every configuration those APIs can produce has to be a correct, solvable, meaningful puzzle. It's a tricky technical problem with a big payoff for our learners.
Engineers at Brilliant think about both "building the right thing" AND "building the thing right" while pursuing high standards of excellence for ourselves, our product, and our codebase.

Balerion AI | Software + FDE + AI Engineers | San Francisco, CA | ONSITE | Full-time | $250k+ base + seed equity | Visa sponsorship available | https://balerion.ai
We're building agentic AI for mortgage lending — automating document processing and income qualification for loan originators.
Underwriting a loan means pulling numbers out of a few hundred pages of paystubs, W-2s, bank statements, and tax returns, then applying underwriting guidelines that run to thousands of pages of edge cases. Most of it is still done by hand.
Problems we actually work on: routing scanned pages to OCR vs. text extraction when the text layer is unreliable; extraction pipelines where a wrong number is much worse than a missing one; running long agent workflows durably so a failure three steps in doesn't restart the whole loan; and evaluating multi-step output against guidelines that are themselves ambiguous. We put real effort into eval infrastructure, because "the demo looked good" does not survive contact with a lender's compliance team.
Stack: Python, PydanticAI, Restate for durable execution, Postgres, AWS. Frontier models from OpenAI and Anthropic plus open-source models where they win on cost or latency.
We raised an $8M seed led by Kleiner Perkins and have paying customers in production. Team previously at Snowflake, PayPal, Twitter, Atlassian, and Microsoft.
Comp: $250k+ base, meaningful seed-stage equity, 5% 401(k) match, full health coverage, commuter stipend, gym membership, daily office breakfast & lunch. Full relocation to SF covered.
Onsite in SF. Visa sponsorship: yes.
Email vishal@balerion.ai with "HN" in the subject, plus a resume or GitHub.

We’re looking for an OpenZFS Developer with:
- Strong C programming skills and understanding of data structures
- Experience with file systems, VFS, and OS internals (threading, locking, IPC, memory management)
Two quick things: what's the hourly rate, and how big is the team at the moment? I've noticed a fair bit of turnover from the company's public activity, so any context on that would be appreciated.

About You: You have a passion for doing things The Right Way, you believe Less is More, you want to focus on Foundations of system design and architecture (pacelc, consistency guarantees), you care as much about what code you do not write, you’re tired of the hype treadmill and care about the fundamentals.

- Langs: TS / Python - Infra: Nix, CDKTF, AWS
We’re hiring from infra to full stack. Come share your proudest firefighting story with us in an interview, bring your GitHub, and let’s see if we’re a good fit!
I'm hiring for a frontline EM building the automation and trust layer for freight pricing, matching, onboarding, and settlement.Lead 1-3 teams (FTE + contractors), own delivery end-to-end, ~8 yrs exp typical. I expect everyone in my eng org (myself included!) to be technical and be able to help unblock the team, though your day-to-day wont be in the code.
Technical here means you can/will get into the code yourself and architecture reviews and maintain technical credibility with our junior to staff/principal level engineers. These are not player-coach roles, but these are frontline roles that need that technical capability.
Interesting problems: trust/fraud at marketplace scale; legacy-data-meets-modern-stack; and all kinds of problems that come with powering hundreds of thousands of load/shipment postings every day.
AI/LLM: We are leaned in, but still hold humans responsible for what they push and expect everyone to review and understand llm output before asking other humans to look at a thing.
Culture: I am deeply familiar with Google's project oxygen/aristotle and am building a culture where our teams can do great work with minimal bs.
Location: Must be local to one of our three locations (Seattle, Portland, Denver).
Mattermost | Remote (US and Canada) | FT | Multiple roles
Mattermost (https://mattermost.com) is an open-core collaboration and workflow automation platform for air-gapped, on-prem and private clouds. Our customers are in defense, intelligence, security and critical infrastructure, including the USAF and NASA. Y Combinator led our Series B, their largest open source investment at the time.
Both openings are full stack on the core platform: Go backend, React/TypeScript frontend, PostgreSQL and Redis. The codebase is public (https://github.com/mattermost/mattermost), so most of what you build is too. We would rather hire people who ship and own complex software end to end than chase an exact stack match, so any systems or backend language and any frontend stack counts. What we look for in both roles: REST and WebSocket APIs with real networking fundamentals (HTTP, connection lifecycle), and relational databases including schema design and query optimization.
We use coding agents daily (Claude Code, Cursor, and others) for scaffolding, refactors, code review and test generation, and we treat that as core craft rather than a shortcut around the fundamentals. If you have a track record of shipping and owning complex software end-to-end, we want to hear from you.
*Senior Full Stack Engineer* $142,723 - $172,723 USD
Architect and ship full stack features end to end, own the testing strategy for what you ship, and build internal tooling and testing infrastructure that makes the rest of the team faster. You will work without close supervision and hold the security and compliance bar our customers require. Nice to have: distributed systems and high availability architecture, regulated-environment security, open-source contributions, experience on remote-first teams.
*Staff Full Stack Engineer* $172,724 - $227,135 USD
Set technical direction for the platform rather than for a feature area: architecture and roadmap across the stack, the standards for how the org uses coding agents, and the strategy for internal tooling and testing. You will influence direction across teams, partner with security and compliance on it, and mentor senior engineers. Nice to have: staff, principal or tech lead experience elsewhere, open-source maintainership, FedRAMP or ITAR familiarity, defense or critical infrastructure background.
Paramark | Software Engineer (L4) | San Francisco HYBRID (3 days/wk) or REMOTE (US) | Full-time | $199K–$249K + equity
Paramark helps Marketing teams optimize spend across all of their channels and programs. There are proven scientific ways to do this, but they are poorly understood and practiced by only a tiny fraction of teams. Our product ingests data from all of our customers' marketing channels and uses it to train open-source ML models for both measurement and experimentation. This makes it possible for any marketer to use these methods.
In this domain, it's hard to figure out what to build, and it's even harder to be both accurate and simple. You'll be joining a small team -- we have four product engineers. That means owning systems end to end and having real influence over what gets built. Your typical project will start with a high level goal, and you will figure out the rest.
Founded 2023, 15 people, $8M from Greylock and others, cash-flow positive. Reasonable working hours: when the Mercury News covered the return of 996 culture, we were the counterexample. "We don't think early stage startup life requires 18-hour days, or even 12-hour days." https://www.mercurynews.com/2025/08/25/silicon-valley-startu.... 4 weeks PTO plus federal holidays, medical/dental/vision (100% of employee premiums, 50% for family).
Looking for 8+ years, full-stack. Some exposure to statistics, experimentation, or A/B testing helps.
Stack: TypeScript, React, Python, Postgres. Google Cloud, Kubernetes, FastAPI, taskiq.
Process: intro call; technical phone screen; one-day onsite in SF (travel covered for remote candidates)
Overture is a vertically integrated, AI-native marketplace for SME acquisitions with listing, valuation, deal rooms, SBA pre-qualification, and capital formation end-to-end. Think TurboTax of business exits, aimed at the baby boomer succession wave (millions of businesses, most with no succession plan).
Who we are: founding team with a decade in fintech, previously backed by Pantera Capital. Platform is close to MVP, pilot structured around ~$5M businesses, fundraise timed to our first deal reaching purchase agreement. In advanced discussions with a top Los Angeles law firm to handle sell-side contracts with one partner already as advisor.
The role: you run sell-side execution on our pilot transactions from engagement through close, and you shape how deal mechanics get productized into the platform. True cofounder: strategy, fundraising presence, significant equity.
You: deep sell-side M&A or IB experience, ideally some in lower middle market ($1M–$25M deals). Comfortable running a transaction hands-on with minimal support. At least one of: fundraising experience, a broker or intermediary network you can bring along, or M&A licensing (Series 79/63 or state broker license a strong plus). Builder's temperament.
As a Senior Security Engineer (Product Security), you will play a significant role in keeping our product safe and secure by building on and maturing Zepto's product security practices. You will work hands-on and shoulder-to-shoulder with Engineering and Product teams, providing guidance and coaching across the software development life cycle while continuing to raise the bar on our security expectations and capability.
This is a security role at its core, but not a gatekeeping one. We are builders – we expect you to read and write production-level code, build tooling and automation, and contribute paved-road solutions that engineers actually want to use.
Reporting to the Security Engineering Lead, you will work closely with them to develop and build Zepto's product security strategy and approach. You will apply a consultative and advisory approach when working with the wider Zepto team, empowering them to work confidently and to use the self-service capabilities you help establish.
We have excellent working relationships with our developers and we need to keep it that way. We are not the team of no. We are the team that helps make things better.
Zepto is moving quickly towards an AI-native way of building and operating. You will be someone who is already experimenting with AI and agentic tooling, or is genuinely keen to, and who is open to developing the skills to secure these systems as we adopt them.
Within the Security team, you are the go-to person for:
Secure development practices
Vulnerability management
Security architecture advice
Working in a scale-up, means you get the opportunity to flex your skills in a variety of ways. We are agile and always willing to roll up our sleeves to get things done. You can, however, expect your day to day to be involved in the following:
Coach engineering teams and collaborate to ensure every step of the software development life cycle follows security best practices
Design, build and maintain security tooling, automation and paved-road controls as production-quality software
Conduct security assessments and architecture reviews of Zepto's applications and services
Embed within project teams to ensure they are effectively considering information security risk and prioritising security controls
Establish and document security architecture and practices in collaboration with the Security Engineering Lead, Product and Engineering teams
Work with the Security Engineering Lead to support Zepto's adoption of AI and agentic systems, and experiment with AI tooling to improve how the Security team works
Help manage application security incidents in collaboration with the rest of the Security team
About us: Fancy ETL pipeline which processes products from huge ecommerce companies. Data extraction and massage, delivery to destinations like Google/Meta/TikTok/etc. Profitable, 18+ yrs stable, 100% employee-owned. No VC, no pointless meetings, just serious coding.
You: 5+ yr senior dev who's seen (and fixed) enough dumpster-fire code to last a lifetime. Python/Django deeply internalized; solid JS skills and able to wrangle Vue/React. You rock backend data pipelines like old jeans: Dagster, Snowflake, DuckDB, Postgres - in the cloud or on your bitchin' VM rack. Docker and Git are second nature. You've embraced agentic coding while still keeping the bots from running the slop show. You play well with others and write code that's easy to live with. Bonus: building AI assistants with PydanticAI, Py2→Py3 migrations, CI/CD and DevOps chops.
Timezones: Primary time zone is PST (standups at 9AM PST). Generally async-friendly but you must reside in the United States and be geographically grounded.
Benefits: 401K match, healthcare/vision/dental, equity, fully remote. Stable company with no time-wasters.

GitHub with kernel-adjacent or LineageOS-type projects a plus. Stack: Android, Linux, C, C++, Java. Filter: send us something you built where you had to fight the OS or hardware.
Hardware Engineer - Bring-up/Debug/Integration - Take EVT/DVT boards and make them work. Comfortable with J-Link and IDE debugging, reading schematics and reference designs. KiCad/Altium/EasyEDA hobby work would make you ideal. PetaLinux experience or hunger to learn it. ECE undergrad fine. Filter: photo of a board you designed or debugged, plus what went wrong.
Hardware Engineer - Power/RF/Wireless - Make the power and RF paths behave on EVT/DVT boards. Hands-on with schematic capture, layout, soldering, scope/logic analyzer. Given two unknowns, you pick one and start measuring. Filter: sensor fusion work, how noise behaves across protocols, and SPI debug chops.
Founder's Office - Work closely with the founder and the rest of the team to manage the day to day and long term affairs of the company, the Man Friday of the company. Must have a decent degree of technical knowledge (we are a tech company after all) and be efficient at administrative tasks as well as management. Speed and learning ability are prized here, there will not always be a clear path to the work you have to do here, so you will have to figure some of it out on your own.
To apply, contact arnav@stpkr.in with the subject line "HN - Human" and a brief intro for further communication. Attach any documents you deem useful there. Please include the role you are applying for at the top of the email if it is one of the above mentioned, otherwise whatever role fits you best. Shortlisting will be online, interviews will be in person. We are hiring quickly, expect to hear back from us within 2-3 days of applying. If you don't, assume you will not. If you are using an AI agent to mass apply for jobs and we can tell, then you will not hear back. Use an expensive one :P (reiterating this, because we receive so much AI spam now. Thanks for your time!
Proxybase | Backend Systems Engineer (Rust) | Remote, Global | Full-Time
Hi HN,
I’m the founder of Proxybase [0]. We’re building a SOCKS5 proxy network focused on transparency and ethical sourcing in the residential proxy market.
A quick note for anyone who applied last month: thank you to everyone who reached out. We received far more strong applications than expected, and between running day-to-day operations and working through the backlog, we took much longer to reply than we should have.
If you applied last month and haven’t heard back yet, I’m sorry for the delay. We’re actively reviewing those applications alongside this new batch.
Why Proxybase?
The residential proxy industry has a rough history. Some providers rely on hidden background scrapers bundled into TV firmware or mobile apps, while others use payout systems that can hold provider funds for months.
We’re trying to build something better:
Open-source clients: Our GUI [1] and CLI [2] are fully open source, so anyone can inspect and audit what runs on their device.
Explicit consent: Providers knowingly opt in. No stealth bundling.
Fair, fast payouts: The minimum payout is $1, sent directly to provider wallets in USD stablecoins. We do not hold funds to earn interest on them.
We’re hiring a Backend Systems Engineer with Rust experience to help build:
Stack: Rust, Tokio, Axum, SOCKS5, Linux systemd daemons, SQLite
Location: Fully remote, async-friendly, flexible time zones
Compensation: Competitive salary plus equity. USD or stablecoin payment options are available.
If you’re interested in building infrastructure for an industry that needs better standards, email jobs@proxybase.xyz with your GitHub, résumé, and a short note about what you’ve been working on recently.
I’ll also be around in the comments to answer questions and hear feedback.
Aerdos | https://www.aerdos.com/ | SF | Full Time | $200-250K + equity
We're building an ai-native intelligence agency to help the USG answer the trickiest national security problems. We do this with lots of public/commercial data and ai.
Astoria AI | Founding AI Engineer — Agentic Systems | Remote (async) | Full-time | Equity-only pre-seed, $190k-$280k + equity post-seed
Astoria AI is building an agentic runtime for human potential — a suite of specialized AI agents serving candidates and companies across the entire hiring and talent lifecycle: career strategy, networking intelligence, verified matching, compliance-native hiring, onboarding, and retention.
The hiring market is structurally broken: 44% of resumes contain fabrications, ATS filters reject 88% of qualified candidates, and 27% of posted jobs are ghost jobs — while regulation (EU AI Act, Mobley v. Workday, FCRA suits) is forcing enterprises to rethink hiring AI. We're building the fix.
You'll own the intelligence layer: LLM-powered agentic workflows (tool use, structured outputs, multi-step orchestration), RAG/retrieval pipelines, lightweight ML for classification/ranking/entity matching, and evaluation loops for hallucination risk and output quality.
Looking for: 6+ years professional SW engineering (Python/TypeScript/APIs/DBs), hands-on experience with LLM APIs and agentic workflows, and ideally RAG/embeddings/vector DB experience beyond basic chatbots.
Stage: pre-launch, pre-seed, founding team, equity-only until seed round closes (~4-6 months), then competitive salary + refresh grants.
Apply: Konstantin.mueller@astoria.ai with „HN“ in subject, plus resume or GitHub
> Commenters: please don't reply to job posts to complain about something. It's off topic here.
But also: while I didn't post this, that's not uncommon for a founding engineer. They're looking for someone to help start the company from scratch, typically with a healthy dose of equity. It's a calculated risk for the engineer, possibly worth anywhere from zero to a gazillion dollars depending on outcome.
I normally wouldn't comment, but expecting someone with that skillset and those kind of opportunities available to them to work for free for 4-6 months with the promise of actual pay "when our seed round closes" was so egregious I couldn't help myself, sorry.
That's common for founders, though. The CEO and CTO etc. are almost certainly in the same boat. They're not so much saying "come work for free" as "come join this group of us who are taking a leap from our current jobs and building something brand new, in hopes it'll pay off wildly."
Kind, smart, low-drama people, seeking the same to help make writing tools authors dream about.
Our users have published thousands of books using Sudowrite, and we're building a sustainable company, not chasing unrealistic growth targets set by VCs.
* We help the next generation of storytellers tell better stories.
* We believe the future of writing is AI & human collaboration.
* Co-founders both had prior exits.
—————————————————————
Hiring: Senior Mobile Developer
* Make writing on a phone a delight.
* You should have: Great taste and product sense, lots of agency, extensive React Native experience, and a sense of humor, adventure, and hope.
River (AI voice agents for B2B sales) | New York, NY | ONSITE | Full-time
We build AI voice agents that run live B2B sales calls — real-time voice, browser-driven product demos, automated follow-up. We're pre-seed, backed by the founders of Ramp, Kalshi, and JumpCloud, revenue is on, and demand is already outpacing what we can serve. It's a genuinely fun problem, and we'd love to find the right people to build it with.
We're hiring two founding engineers. To save everyone's time, here's what the role really needs — if a few of these are a strong yes, we'd love to hear from you:
NYC-based and up for working in person (5 days). We're not able to do relocation or visa sponsorship right now.
TypeScript/Node as your main production stack — the one you actually ship in day to day.
You've shipped real software that real people used — something in production, with revenue, or a startup you built (not tutorials or coursework).
You've built something real with LLM APIs.
You like owning things end to end — finding the problem and fixing it without waiting for a spec.
Two levels:
Founding Backend Engineer (5+ yrs): real-time/streaming depth (WebRTC, voice, low-latency), plus infra and reliability ownership.
Founding Product Engineer (2–4 yrs): frontend-leaning (React/Next.js), customer-facing, CS degree or equivalent standout shipped work.
No need for a formal resume — just send a link to something you're proud of that real people used, and a line on what you owned. We read every one.
New Lantern | https://newlantern.ai | Software engineers (backend and generalist product engineers, founding recruiter) | Full time in San Francisco, CA (ONSITE)
New Lantern is building an AI radiology resident—think Cursor for radiologists. Our application integrates the three software tools radiologists use all day [1], together with AI, to create a platform that saves radiologists toil and lets them focus on reading images and finding disease.
We are a series A startup with ~20 engineers (~40 total staff), have a number of live customers generating revenue, plenty of runway, and are backed by Benchmark, Anthropic, and other great investors. Our customers have told us they would cry if they couldn't use our product anymore.
We're hiring for backend and product engineering, as well as a founding recruiter to help us scale. You'll work directly with our founder/CEO, our staff radiologists, and our end users to build a product that radiologists rely on daily. You'll have real ownership and autonomy, and ship meaningful work frequently.
I'm Steve, New Lantern's Head of Engineering. If you're interested or want to learn more, shoot me a note at (my HN username)@newlantern.ai. I've already hired one engineer from HN this year and interviewed many more!

We The Flywheel | AI-Native Engineers & Operators | REMOTE (worldwide) | Contract / Part-time (10–40 hrs/wk)
We're a remote-first digital product studio building across sports media, AI, fitness, and personal branding — 500+ web properties and deeply AI-native workflows. AI does the heavy lifting here, but it's the leverage, not the point: we hire for the human judgment, ingenuity, and taste on top of it.
Open now:
* Agentic PR Coordinator — media lists, outreach, drafting, and AI-assisted PR workflows for earned media. Entry-level, 10–40 hrs/week.
* Agentic-Led Social Media Marketer — AI-native social media management: content, scheduling, and performance across channels. 10–40 hrs/week.
* Production Designer — brand and marketing asset production using AI tooling. 10–40 hrs/week.
Also open: Agentic Engineer, Sr Agentic Engineer, Agentic Operations Coordinator, Agentic Operator, AI Operator Team Lead, Creative Copywriter & Storyteller, and more.
It would be good to indicate if you are open to engineers in Europe or the UK and what hourly salary they should be expecting. The other locations you list are considerably cheaper and might indicate you aren't paying enough to support talent from these geographies.

Statecraft | Forward Deployed Engineer (All Levels) | REMOTE (US) | $160-220k + equity
At Statecraft, we are building an AI workforce to help automate the US government. Currently our government is operated almost entirely by consultants who outnumber public servants 3:1 and institutionalize inefficiency so they can bill more hours. This only leads to agencies struggling to meet their missions, overworked and underpaid public servants, and overburdened taxpayers.
Most of what these consultants do is easily automatable: data entry, basic spreadsheet work, filling out paperwork, etc.; we do this with AI and save taxpayers ~80% on average while completing the work ~10x faster with 2-3x less errors.
We're a small, lean, mission-driven team and hiring Forward Deployed Engineers to build use cases and integrate deeply with agency customers. You'll be working with critical systems, massive surface area and national impact.
* This position requires U.S. citizenship and the ability to obtain/maintain a security clearance.

Source (https://source.inc)| USA/Canada: REMOTE | Full-Time
Our mission: make handling memory, state, and context for AI agents outside the cloud as simple as it is in the cloud. Today it isn't close. An agent without data is inert, and outside the cloud, data is duct tape.
An agent in the field needs data that is verifiable, auditable, concurrent, collaborative, and permissioned. No single system gives you all five. SQLite gives you local storage and nothing else. Every other database assumes the cloud is there to provide the rest.
We're building the data layer agents actually run on: local-first, syncs peer to peer, every write verifiable, every read auditable, no cloud required. The stack is open source: https://github.com/sourcenetwork/defradb. We think it's the best memory an agent can have, bar none.

What are the EU roles you specify here? career page is position specific and not broad like you seem to suggest
Yeah The Who's hiring format isn't a perfect fit for how we have it structured. In general, engineering can hire remote first if there's a good fit, and we have local entities or EOR processes for every EU country (to the best of my understanding)
MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite
We make robots that autonomously construct buildings, starting with bricklaying.
There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run.
We're looking for experienced software engineers for many roles. You can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium
We're rapidly scaling up operations - we'll be building in the UK soon - and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

Wikimedia Foundation | Lead Product Manager, Security | REMOTE (US + 18 countries) | Full-time
I lead the security and safety team for Wikipedia, at the Wikimedia Foundation. I’m hiring a product manager to lead our security roadmap and steer the priorities of our security engineering team.
It’s a high-pace, shipping-heavy time for the whole project right now, as we are dedicating ourselves to surviving all the ways AI is messing with us and the internet, and getting to the other side of it. I joined myself about a year ago, and have found it to be a great time and place to swing big and surprise people.
This is a PM role and PM background is certainly helpful, but it’s not strictly required (everyone has the first PM job at some point). A technical background and security expertise are a must for this role, so we’re also open to people in engineering roles, who have demonstrated PM-relevant skills and are interested in making a pivot.
You can apply at https://job-boards.greenhouse.io/wikimedia/jobs/8140060?gh_s... - we don’t auto-filter based on AI or anything like that, I will personally see your resume.
I‘ve been considering applying at WikiMedia for a while now, but [my country] is not in the listed countries. Is there a chance you‘ll expand this list in the future?
Ah, that is too bad. It's certainly always possible the countries list could expand in future, but it's not something I have insight into and unfortunately can't give you too much to go on.

Cardog | Toronto, Canada or REMOTE | Full-time https://cardog.app/careers
We're the system of record for the Canadian vehicle: raw automotive data turned into facts that can be checked. Our open-source VIN decoder sits underneath a government vehicle registry.
Some of what's interesting:
- A government registry, a manufacturer's own filing, a listing site and an insurance record will describe the same truck four different ways, and nothing in any of those files says they're the same truck. Reconciling that, for every vehicle in the country, in a way that holds up when a regulator asks how you know, is most of the data work.
- Seventeen characters on a door frame encode manufacturer, plant, model year and build attributes — badly, inconsistently, and differently per manufacturer. Public reference data covers some of it. The rest gets worked out from filings, recall documents, and patterns inferred across millions of vehicles.
- We read vehicles directly over OBD-II now. Forty modules answered on a recent Hyundai, each reporting its own part number and installed software version. Nothing downstream of the VIN moves when a module is reflashed, so no registration, history report or dealer system knows what software is actually in a car.
Hiring: VIN Decode Engineer, Data Platform Engineer, Infrastructure Engineer, Founding Engineer (dealer platform). TypeScript, Postgres, Cloudflare Workers.

Trustworthy Technology | Earth | Part Time | REMOTE | Vision, Marketing, and/or Design
Hi, we are a small group trying to bring the "trustworthy" feature back to tech. Curating and building a FOSS+ toolset, storefront, and eventually online service—all to support freedom, privacy, and informed consent—on device and on the net.
We've written our thoughts and research down at: https://trustworthy.technology/ and we have a few geeks starting projects at: https://codeberg.org/aol
First off, you'll notice that you've not heard about this project before. Next, the message is a bit scattered, and the "programmer art," while arguably not horrible isn't winning any awards either, haha.
That's where you come in.
You are one of the few folks who really cares about this stuff, and also a graphic/product designer, or perhaps a digital marketer, communicator or "people whisperer." (Being in the EU would be helpful as well, to work from the digital sovereignty angle, though not required.)
Some of us are unemployed and currently donating our time. Maybe you are too, or retired/cashed-out and bored. Consider this another FOSS-like project. We hope the store/service will make money, but we're not there yet.
Interested? Let's chat at: https://trustytech.zulipchat.com/join/h5usqnt2bet7exz747cbf3...
BTW, if/when you join please say hi let us know what kind of projects you're interested in.

Great Question | Product Engineer | Remote (Canada) | Full-time | https://greatquestion.com
Great Question is the best way to understand your customers - whether it's mining what they've already told you, or generating new research via interviews, surveys and prototype tests. We're 2nd time founders, closed our Series A last year, with customers from Canva & Brex to Intuit & Amazon.
We're hiring product engineers to help us push the envelope on what's possible in AI engineering practices, while helping our customers bake customer insight into every product release.
You'll do well here if you have a strong sense of what makes a quality product, you're AI native, and you solve the problem of ambiguity with getting closer to customers.
We're hiring product engineers!

Pagelove | https://pagelove.com | Founding Software Engineer | REMOTE | Full-time | $110k–$130k + early equity
Pagelove collapses the modern web stack into its simplest form: no databases, no APIs, no application servers. Just HTML that works like an app, scales like a CDN, and is AI-native by design.
The page becomes the application, API and persisted state. Humans and machines can read and update the same surface directly using CSS selectors over HTTP, rather than through separate HTML and API/MCP interfaces. With Pagelove, AI can finally build web applications without having to deal with the complexity of the full stack.
We’re seed-stage and well-funded, hiring our first non-founder engineer. The codebase is Rust, with work including distributed storage, HTTP caching/ETags, CRDTs, parser/DOM performance, CI and production infrastructure.
Our development process is heavily agentic: Claude Code and Codex do substantial implementation work, with humans focused on architecture, review and the hard problems.

Tufalabs | Zurich, ONSITE | Full-time | 100-200k CHF | https://tufalabs.ai/
(I want to preface that we don't have a ton of budget to expand our team right now and we want to keep the team small, but I also don't want to miss someone who would be a great fit)
We are a self-funded independent AI research lab in Zurich. Currently we explore ARC-AGI3, LLM/RL reasoning, and quant. We recently started a new LLM post-training and pre-training effort, led by some ex-engineers from the swissAI Apertus team. We also like to do some Kaggle on the side, our team includes the top #3 and #12 globally.
Our overall roadmap is to catch up with LLM capabilities, own the full stack, and use it to do our own independent research, pushing efficiency and looking for new paradigms. We expect our new cluster (2x NVL GB300) to be up by the end of the month.
Long term we want to switch to AI alignment/safety research as I believe this is all that matters when AI capability is high enough.
We look for people who are driven, who believe it's possible to make significant contributions to both AI capabilities and safety, and with previous experience pre-training and post-training LLMs and related infra.
If interested, email me at benjamin at tufalabs ai.
Biobase | Senior Technical Product Engineer, Technical Product Engineer (Early Career) | REMOTE (US, Canada) | Full-time | $150–230k / $90–170k + equity
Biobase has grand ambitions. We broker biospecimens, whole slide images, and the clinical metadata attached to them, on a supply-chain backbone that we're steadily automating. We’re building healthcare-data-focused agents on top of the datasets that we’re assembling, too.
We'd rather build the thing that removes the work than throw people at it. Two roles, one team, both reporting to the CPO:
Senior Technical Product Engineer ($150–230k + meaningful equity). The product team's technical interface. Architecture decisions and code review on the platform (Python/FastAPI, TypeScript/React, Postgres, Azure); the data pipeline and informatics that take specimen, slide, and clinical data in from suppliers and labs; and product ownership of the internal platform that builds our agents (permissions, evals, cost control, guardrails for sensitive data). You've been the reviewer of record somewhere, you've operated what you shipped, and you think in business problems before tickets.
Technical Product Engineer, early career ($90–170k + equity). Same territory at an earlier stage: the platform, the data pipeline and informatics, and the agents we run against our own operations — with a senior product engineer and our lead engineer reviewing your work and pairing when it helps. Open on background – self-taught, bootcamp, degree, research lab, a career you're leaving – selective on the bar. You've built something and someone else used it.
We build with Claude Code every day and expect you to become both fluent with it and skeptical of it. No ticket queue, no spec handed to you. Comp is salary + equity combos you choose between.
Full postings: https://biobase.ai/careers
To apply: email jobs@biobase.ai with something you built that eliminated manual work and what happened after it shipped. Links over resumes, no cover letter.

Deya | Multiple Roles | New York, NY | HYBRID (NYC) or REMOTE | Full-time | https://deya.health/careers/
Everyone in health AI is chasing scribes and diagnostics. Almost no one is building the longitudinal data layer that captures what actually happens to patients over time. That is the real moat, and we are building it for eye care.
Deya sits between doctor and patient, capturing symptoms, treatments, outcomes and ocular images over time. Clinician-led, piloting with eye doctors, and we hold the largest dataset of eye images captured on smartphones. We build with AI tools daily.
Three roles, all high ownership:
Software Engineer (AI x Healthcare) - Product and infra from 0 to 1. Next.js, backend, cloud, agentic workflows, longitudinal clinical data.
Mobile Engineer (React Native, Swift, Kotlin) - A modern phone is already a clinical instrument and almost none of it has been pointed at eye care. Own the app and its UX end to end.
AI Engineer (Computer Vision + LLMs) - Own the vision pipeline turning phone photos into clinical signal, plus the LLM systems reasoning over patient history.
We have a proprietary clinical dataset and because we control capture, you can improve the data itself rather than model around its limits. Optometrists and ophthalmologists in-house to define ground truth and validate the work. Competitive salary plus equity.
All three roles and apply: https://deya.health/careers/

Vitalize | Senior Product Manager or Staff Product Manager | San Francisco (hybrid)
What we do: Hospitals run critical operations (staffing, labor planning, and capacity) on spreadsheets, phone calls, and gut instinct. Labor is the biggest cost and hardest operational problem, and it’s still largely manual. Vitalize is building the operating system for hospital labor (and ultimately capacity): we forecast demand from real hospital data (e.g., ADT + historical patterns + acuity) and translate that into concrete staffing decisions: next month’s schedule and the next shift.
Traction: - ~$37M raised - Launched 2024; ~$13M committed ARR across 10+ health systems - Live in 20+ hospitals and growing quickly
The role: We're hiring a PM to own the product experience that takes a hospital from signed contract to successfully using Vitalize in production. Getting there is complex: every health system has its own HRIS, scheduling workflows, union rules, and technical environment. This team builds the custom integrations and internal tooling that make those deployments faster, more repeatable, and less manual as we scale.
We're looking for a PM who... - Led messy third-party enterprise integrations deep enough to make real technical calls with eng - Has built internal tooling with an internal team as the customer - Prioritized a roadmap under live GTM pressure and held the line when the loudest deal wasn't the right build - Startup experience, where the system you were building didn't exist yet
If you're interested, email me mark@vitalize.care
Comp: $215K-$260K + equity
Apex Space | Multiple Roles | Full-Time | Onsite | Los Angeles, CA | apexspace.com
Apex Space is building standardized spacecraft platforms to enable true mass-production of spacecraft and enabling getting varied and similarly mass-produced payloads to orbit.
We're hiring everything from technicians to product/project managers and supply chain to all sorts of engineers: thermal, mechanical, mechanisms, solar, optical, power systems, electronics/avionics, PCB, embedded software, ground software, devops, and more.
You can apply at https://www.apexspace.com/careers. Or, email me with a resume at maabonnet [at] gmail [dot] com, and I'll see if I can get you a direct referral link so that you get a call with a recruiter ASAP if you're a particularly good fit.
NOTE: Due to federal law, you must be a US person (citizen, green card holder, some other classifications) to work at Apex Space. Please state your residency or citizenship status in your email. If you are not a US person, I can't help you.
I think I'd be a strong fit for some of your roles, but the benefits advertised read to me like the absolute bare minimum to meet industry norms. Is there anything you would say is a real advantage for Apex?

Quill | Fullstack SWE | Full-time | Remote, PT/ET hours preferred | $150 - 210K USD + equity | https://quill.co/
I’m a co-founder of Quill, a fullstack SDK for adding customer-facing analytics & data features to your app. Backed by YCombinator & top-tier SV-based investors (fundraising not publicly disclosed; happy to share any details when we chat).
Some examples of how customers get value from Quill: • pre-IPO fintech adds custom reporting & data export features to their money movement product. • Series B healthtech is now able to deliver completely custom in-product reports & dashboards to every enterprise customer they onboard. • Series A govtech adds analytics and reporting capabilities within their existing agent/chat product.
Reasons you’d love working with us: • Work with a small, focused, talented team on a highly technical product (by developers for developers). • Funded company in a big market, but still prelaunch with a team size <5 • High level of product ownership with tight feedback loops: the products you build are shipped quickly and get used by real customers immediately. Our latest hire built our entire CLI product from 0 -> 1, and it was used in production by customers the day it shipped.
We are growing the team to keep up with demand for new features that our customers are asking us for, while also preparing for launch. We're looking for someone that will make us better. We’re just getting started, and want you to bring your opinions, expertise, and experience to the table (not just execute on the ideas we already have).

Snout plans pay for 100% of routine veterinary care, unlimited visits, and additional member benefits - think pet insurance, that you will actually use every year.
We're growing the team and hiring across the board. Open roles:
Full-Stack Software Engineer - Build and ship every day across our web apps, payments, and data systems, from database to UI.
Across all roles we're looking for at least three years of relevant experience, and we're hiring senior and staff level engineers as well.
Our tech stack includes Node.js, React, PostgreSQL, AWS, Tailwind, and Python. We use both JavaScript and TypeScript heavily. Our team uses LLM-based tooling day to day, but we're fundamentally a human-centric team, and our product itself does not heavily feature AI components.

Looks like they have an accidental “d” at the end of the link.
Remove that and you get https://jobs.gem.com/snout

Or maybe a typo, still, I'd have left the link unstated.

I find it hard to imagine that would be the case. They already link to the same page from their website without any typos, and they link to their website from the comment here.

G-Research | https://www.gresearch.com | London UK, on-site | Full-time
G-Research is a leading quant finance company. Big compute farm, interesting problems.
My team is hiring senior engineers to work on our (actually world class) DAG scheduling infra for distributing research and production workloads across the compute farm. What we do is roughly:
* maintain and improve the SDKs for that scheduler in Python, F#, and C#
* add interesting new features to the scheduler itself
* maintain and improve a web backend and UI for quants and engineers to monitor their jobs, increasingly with high availability requirements

Mingla | CTO (ONSITE, Stockholm) or Part-time Engineer (REMOTE ok) | https://mingla.com
Mingla makes strangers meet at in-person events: attendees scan a QR code and are straight in — no App Store, no signup — gamified missions start real conversations, and the organizer gets proof of what happened in the room.
You'd own the platform end to end: Elixir/Phoenix backend (Ash, GraphQL, Postgres) and a native SwiftUI iOS app — the QR entry is an App Clip. We're open to two setups: a full-time CTO onsite in Stockholm, or a part-time engineer who can work remote.
Apply: hello@mingla.io, subject "HN: CTO / Engineer", with a link to something you've built and one line on which setup fits you. No cover letter needed.
Axo | Lead Founding Engineer | Sugar Land / Houston, TX (HYBRID) | Full-time | $120k–$160k + Founding Equity
Want to help out healthcare providers? Clinicians using our software are already saving hours a day and loving their job again. We are building Axo to make the software layer as invisible and ambient as possible, letting clinicians direct 100% of their attention to patients rather than screens.
Our first market is orthotics and prosthetics (O&P), the field designing braces and artificial limbs that restore human mobility and underserved by the tech sector. You’ll join as a founding engineer working directly with myself (former Google SWE) and my co-founder (one of the US's best known O&P clinicians), and small engineering team we want to grow.
You will own massive surfaces end-to-end, making foundational architectural decisions for our entire platform. We've got a massive pipeline ahead and need your help to build it. And we participate in humanitarian missions to expand prosthetic access in critical parts of the world like Ukraine and Sri Lanka.
- The Stack: C#/.NET, gRPC, SolidJS/TypeScript, and PostgreSQL, built with strict domain-driven design and rigorous testing.
- How we work: Flexibility! Love AI-assisted speed coding? Go for it. Prefer to write by hand because your mental model is faster than prompting? Perfect. We only care about delivering safely and quickly.
- Requirements: Senior-level depth with production systems, a strong habit of domain modeling, and a philosophy that defaults to simplicity. Strong UI/UX experience with an obsession for user simplicity is a must.
To apply, email me directly at jlyman@axoventures.co with a short story about a favorite technical challenge you solved end-to-end. Please put "HN" in the subject line! MUST be in Texas.
Silkline | Software Engineer | Chicago, Seattle | ONSITE (5 days/week) | $150k-$225k + equity | https://silkline.ai
Modern hardware supply chains run on spreadsheets, email, PDFs, and prayer. It's like fax woke up in 2026. We're fixing it with an AI-first procurement platform for aerospace, defense, and nuclear manufacturing - customers include Machina Labs, Astranis, K2 Space, Castelion, and Antares.
At SmallSat last month, a supplier walked up to me (in a full spacesuit costume), said "oh you're from Silkline, we love you guys!" and handed us a roadmap item on the spot. That's the job: sit with customers, hear what's broken, ship it. 0-1 product, real UI/UX ownership, ERP integrations that sync POs and manufacturing data.
Stack: TypeScript, React, Next.js, GraphQL, Trigger.dev. You: 5+ years full-stack, startup or 0-1 experience, fast with APIs (bonus: ERPs). The role touches ITAR-controlled data, so US persons only, no visa sponsorship.
We 5x'd our customer base this past year and continue to grow fast. Small team, direct line to the founders (Isaac and myself). Also: space-suited mascot named Silky.

We're hiring an Onboard Technology Manager to own everything that keeps passengers connected and crew productive on the train: Wi-Fi and network infrastructure, onboard units, and mobile devices for train staff. As satellite constellations and 5G redefine what's possible for high-speed mobile connectivity, you'll help set the direction for the technology being adopted on the largest non-governmental train fleet: writing specs, defining network architectures, monitoring live performance, and driving improvement projects from their conception to the finish line.
The role is highly cross-functional. You'll work with internal partners (operations, customer product, and rail engineering) and external ones, such as tech vendors (Icomera and Advantech) and train manufacturers (Siemens, Talgo).
What we're looking for:
- Bachelor's or Master's in Telecommunications, CS, Electrical Engineering, or similar
- 2+ years hands-on with network architecture, Wi-Fi systems, or Mobile Device Management (ideally in rail or a similarly complex environment)
- Strong troubleshooting skills on complex networked systems
- Comfortable leading cross-functional initiatives and communicating clearly with both engineers and non-technical stakeholders
- Fluent German and English (internally, English is preferred, but German is often mandatory when working with suppliers and regulatory bodies)
Perks: hybrid office/remote work model, up to 60 extra remote days/year from abroad (work from anywhere), 12 free FlixTrain travel vouchers/year + 12 for friends and family, mental health support, L&D budget, mentoring program.

Discord | Senior Software Engineer, Application Security | San Francisco, CA | ONSITE | $280K–$330K TC
Discord is where communities and friend groups spend time together, on desktop, mobile, and now more and more inside games and third-party apps built on our platform. That surface area, plus a huge, engaged, occasionally adversarial user base, makes application security a genuinely hard and interesting problem here.
We're hiring a Senior Application Security Engineer to join the Product Security team. Responsibilities include threat modeling and secure design review with product and platform teams, building and improving AppSec tooling (SAST/DAST/dependency scanning), and working directly with engineering teams to remediate findings.

Snowflake | Forward Deployed Engineer, Product Manager | Menlo Park, CA | Warsaw, Poland | London, UK | ONSITE
I’m part of Snowflake’s Applied AI / Forward Deployed Engineering team, and we’re hiring for multiple roles on the team.
We work directly with strategic customers to design, build, deploy, and improve production AI systems on Snowflake. That includes LLM applications, RAG and agentic workflows, evaluation frameworks, guardrails, observability, and production iteration using Snowpark, Cortex, and Snowflake’s native AI capabilities.
For the FDE role, we’re looking for strong engineers who can build and ship customer-facing AI systems end to end, especially if you’ve worked on LLM apps and care deeply about evals and quality. For the Senior role, we’re looking for someone who can lead multi-engineer AI engagements, mentor other engineers, and still be hands-on in architecture and implementation. The roles are customer-facing and involve travel, including at least 25% onsite time with strategic customers.
If you like working in ambiguity, building real AI systems instead of demos, and partnering closely with customers to get things into production, these roles are a good fit.

Railway | Senior Product Eng (full-stack), Brand Designer - Web, Senior Growth Marketer, Senior Product Marketer, Account Executive, Scale| REMOTE (Worldwide) | https://railway.com/careers
Do you feel scared and alone when opening the AWS console? Do you wish you could just tell Claude to manage your infra, and it would just work? Do you dream of a future where software is abundant and developers and normies alike are free to build their wildest dreams?
We're Railway, and we think infrastructure can be better. We're working at the forefront distributed systems engineering, interface design, and agentic computing to bring about the infrastructure platform we've always wanted. So far we've built out a platform loved by 3M+ users and we're just getting started.
Fair warning! The problems are complex: racking and stacking servers, home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.

Noricum | Senior Backend Engineer, Payments, Ledger & Provable Fairness | REMOTE (2h overlap with US Pacific) | Contract to permanent | $120-160/hr | Start by 14 Sep
I'm the founder of Noricum where we build platforms – currently the money infrastructure, ledger, engine and payment rails behind a pre-launch wagering platform with a Steam skins economy. The games, a cashier and a bet ledger are built and live as a front end, with written specs for the server contract: ledger schema, refusal table, round lifecycle, every game's arithmetic. Processing and licensing are secured. The server does not exist. That is the job. You would own:
- A server-authoritative game engine - seeds, nonces, outcome computation - A double-entry ledger where balance is derived and no client write can change it - Server-side enforcement of every limit and refusal - Payment rails idempotent under duplicated webhooks - Seed custody and the provably-fair lifecycle - An affiliate system with referral attribution and commission payouts
Must have shipped: a double-entry ledger or equivalent money system in production, a payment integration including webhook idempotency, auth and sessions you built and operated, and infrastructure you owned end to end. Provably-fair systems, settlement-side gaming or trading infra, or Steam trade automation all stand out.
Email michael@noricum.io with your start date and a few lines on the last money system you shipped - what it guaranteed, and how you knew it held.
ODK | Senior Product Manager | Remote (Worldwide) | Long-term contract, 30–40 hours/week | $90–$110/hour USD
ODK is an open-source platform used by thousands of organizations worldwide to collect billions of data points for disease surveillance, supply chain traceability, environmental monitoring, and more. It enables users to build powerful forms and reliably collect structured data, even in places with little or no Internet connectivity.
ODK has been actively developed for 18 years. We have a mix of self-hosted and SaaS users across many sectors. We're looking for a senior product manager who will own product discovery and prioritization across this diverse user base. To be successful, you'll need to find the common needs behind very different workflows and turn them into opinionated product improvements.
Because the team is small and the user base is large, this is a high-autonomy role where product decisions have an unusually direct impact. You should have substantial experience managing complex B2B or technical products. Experience with open source, self-hosted software, and small, fully remote teams is a plus.

Renaissance Philanthropy | Research Engineer (Speech AI/ML) | Remote (worldwide)
Renaissance Philanthropy's aim is to activate a virtuous circle of increasing ambition and impact between philanthropists and innovators: by identifying frontier experts both in science and in new ways of solving problems; by tapping into the growing number of emerging philanthropists; and by building multi-sector initiatives that can harness the power of philanthropy, markets, and governments.
RenPhil's Engineering Hub supports mission-driven, grant-funded educational technology projects that seek to improve educational outcomes in fundamental skills like math and reading. This summer we're launching a program called LEVI Literacy, which has a goal of halving the number of struggling readers in the US within 5 years.
We're looking for an expert in modern voice AI to support this work. Our partner teams are building tools that assess and support early reading directly from children's speech in real classrooms — oral reading, spoken vocabulary tasks, whole-class instruction. These are hard, meaningful speech problems: young children's voices, noisy multi-speaker environments, and high stakes for getting it right — and fair — for every student.
We're looking for folks who:
- have built and operated production ASR or speech-processing systems
- know the full data-to-model pipeline: collection, annotation, fine-tuning, evaluation, and deployment
- can speak the languages of both research and engineering
- want to help create a world where all children learn to read well.

Sunspell | Founding Engineer | New York, NY | ONSITE | Full-time | https://sunspell.fm/careers/founding-engineer
Six-person venture lab in New York. We build our own products. A studio arm does client work, is profitable, and pays for the rest.
Our founder ran her own design studio and was the founding design partner on Partiful, on Sentropy before Discord bought it, on Goldcast before Cvent, on Make before Celonis, and on Descartes Labs. She builds here now instead of for other people.
You would own the production application around our intelligence layer. Architecture, frontend, backend, Postgres, durable execution state, retries and idempotency, permissions, deploys, and the data-heavy interfaces people work inside all day: tables, relationships, filters, history, approvals. React and TypeScript at depth, Node or Python behind it. We write a lot of MCP servers and build with Claude Code daily.
Seven-plus years shipping, hands on code within the last year. Design and engineering sit in the same room here. There is no handoff.
Most people who apply like the words "founding engineer." We are looking for someone who has already started something of their own.
Ownership. You should own a piece of what you build here. We are not going to post a percentage, because the honest answer depends on what you end up carrying, and we would rather work that out with you than hand you a number that pretends to be precise. It is a conversation, it is flexible, and we intend it to be fair.
We are six people. Nothing you build goes through a committee before it ships. Nothing you break, you fix alone. We are a tight team today and we are looking to double it by the end of the year.
Please send your resume or GitHub, plus the most ambitious thing you have built mostly on your own. Rough work that worked beats polished that never shipped.
If this is not you but a name comes to mind, please pass it along. :)

The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.
We announced our $42M Series B earlier this year! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.
We’re looking for product-minded, high ownership engineers to join our team! The Engineering team is HQ’d in SF, but we’re growing in NYC now too!
We’re hiring for 4 Senior SWEs, 1 MLE and 1 AI PM in SF, and 2 Staff SWEs in NYC. Engineers own projects end-to-end so full stack ability is expected.
Check out our open roles here: https://shepherdinsurance.com/careers
Our stack includes: Typescript, React, Next.js, GraphQL w/ Apollo, Node.js, Postgres & Redis
– If you have experience building AI agents or multi-step reasoning systems, we’d love to hear from you.
* In the form, be sure to mention that you heard about this opportunity via Hacker News.

Stand | San Francisco, CA | ONSITE
We're building the intelligence layer for physical risk: digital twins of individual homes, run through physics-informed AI World Models, to see exactly how a specific property will perform in a wildfire or hurricane — traditional models only guess at the neighborhood level. That precision lets us do what insurers historically couldn't: measure how much a new roof, cleared vegetation, or better siding actually cuts risk, then price coverage accordingly, turning mitigation into a real financial incentive instead of just advice.
We've scaled to ~$10B in insured assets in just two states in under a year. The interesting problems: ML surrogates that run physics simulations 1,000x+ faster without losing accuracy, structure-level digital twins built from imagery and property data at scale, and systems that reason across risk, cost, and homeowner tradeoffs — we're hiring across engineering and applied science.

Brilliant.org | Senior/Staff Software Engineer (Interactives) | Remote (North America), SF, NYC | Full-time | $180k-$250k | https://brilliant.org
Brilliant is building the world's first graphical AI tutor: a collection of interactive learning experiences that both the learner and their AI tutor can see and manipulate. In a world of cognitive offloading, Brilliant's AI gets people to actually think and solve hard problems.
We're hiring an interactive-focused engineer to craft the building blocks that power it. Each interactive exposes an API used by learning designers, our authoring agents, and the tutor itself. And every configuration those APIs can produce has to be a correct, solvable, meaningful puzzle. It's a tricky technical problem with a big payoff for our learners.
Engineers at Brilliant think about both "building the right thing" AND "building the thing right" while pursuing high standards of excellence for ourselves, our product, and our codebase.
If you're energized by the prospect of doing the best work of your career and changing how the world learns, you can learn more and apply here: https://brilliant.org/careers.
Balerion AI | Software + FDE + AI Engineers | San Francisco, CA | ONSITE | Full-time | $250k+ base + seed equity | Visa sponsorship available | https://balerion.ai
We're building agentic AI for mortgage lending — automating document processing and income qualification for loan originators.
Underwriting a loan means pulling numbers out of a few hundred pages of paystubs, W-2s, bank statements, and tax returns, then applying underwriting guidelines that run to thousands of pages of edge cases. Most of it is still done by hand.
Problems we actually work on: routing scanned pages to OCR vs. text extraction when the text layer is unreliable; extraction pipelines where a wrong number is much worse than a missing one; running long agent workflows durably so a failure three steps in doesn't restart the whole loan; and evaluating multi-step output against guidelines that are themselves ambiguous. We put real effort into eval infrastructure, because "the demo looked good" does not survive contact with a lender's compliance team.
Stack: Python, PydanticAI, Restate for durable execution, Postgres, AWS. Frontier models from OpenAI and Anthropic plus open-source models where they win on cost or latency.
We raised an $8M seed led by Kleiner Perkins and have paying customers in production. Team previously at Snowflake, PayPal, Twitter, Atlassian, and Microsoft.
Comp: $250k+ base, meaningful seed-stage equity, 5% 401(k) match, full health coverage, commuter stipend, gym membership, daily office breakfast & lunch. Full relocation to SF covered.
Onsite in SF. Visa sponsorship: yes.
Email vishal@balerion.ai with "HN" in the subject, plus a resume or GitHub.
Location: Florianopolis, Brazil (UTC-3)
Remote: Yes
Willing to relocate: Not yet
Technologies: Node.js, TypeScript, PostgreSQL, Azure, MongoDB

It would also be nice to note if it's 6DWW or 7DWW. I've been told GenZ is very into the these options.

Anterior | Software Engineers | NYC | Onsite | Full Time
Anterior is improving the experience of healthcare for everyone. Our agentic orchestration platform makes clinical decisioning frictionless for RNs and MDs.
About You: You have a passion for doing things The Right Way, you believe Less is More, you want to focus on Foundations of system design and architecture (pacelc, consistency guarantees), you care as much about what code you do not write, you’re tired of the hype treadmill and care about the fundamentals. You have battle scars from overengineered and underperforming slop, and you care about writing code that lasts.

DAT | Frontline Engineering Manager, Senior Engineering Manager | Seattle, Portland, Denver | Hybrid 2-3 days/week | Full-time | $192k - $261k
I'm hiring for a frontline EM building the automation and trust layer for freight pricing, matching, onboarding, and settlement.Lead 1-3 teams (FTE + contractors), own delivery end-to-end, ~8 yrs exp typical. I expect everyone in my eng org (myself included!) to be technical and be able to help unblock the team, though your day-to-day wont be in the code.
Technical here means you can/will get into the code yourself and architecture reviews and maintain technical credibility with our junior to staff/principal level engineers. These are not player-coach roles, but these are frontline roles that need that technical capability.
Interesting problems: trust/fraud at marketplace scale; legacy-data-meets-modern-stack; and all kinds of problems that come with powering hundreds of thousands of load/shipment postings every day.
AI/LLM: We are leaned in, but still hold humans responsible for what they push and expect everyone to review and understand llm output before asking other humans to look at a thing.
Culture: I am deeply familiar with Google's project oxygen/aristotle and am building a culture where our teams can do great work with minimal bs.
Location: Must be local to one of our three locations (Seattle, Portland, Denver).
Primary Tech: Node/TS, React, GraphQL, Kafka/redpanda, k8s, AWS, etc

Mattermost | Remote (US and Canada) | FT | Multiple roles
Mattermost (https://mattermost.com) is an open-core collaboration and workflow automation platform for air-gapped, on-prem and private clouds. Our customers are in defense, intelligence, security and critical infrastructure, including the USAF and NASA. Y Combinator led our Series B, their largest open source investment at the time.
Both openings are full stack on the core platform: Go backend, React/TypeScript frontend, PostgreSQL and Redis. The codebase is public (https://github.com/mattermost/mattermost), so most of what you build is too. We would rather hire people who ship and own complex software end to end than chase an exact stack match, so any systems or backend language and any frontend stack counts. What we look for in both roles: REST and WebSocket APIs with real networking fundamentals (HTTP, connection lifecycle), and relational databases including schema design and query optimization.
We use coding agents daily (Claude Code, Cursor, and others) for scaffolding, refactors, code review and test generation, and we treat that as core craft rather than a shortcut around the fundamentals. If you have a track record of shipping and owning complex software end-to-end, we want to hear from you.
*Senior Full Stack Engineer* $142,723 - $172,723 USD Architect and ship full stack features end to end, own the testing strategy for what you ship, and build internal tooling and testing infrastructure that makes the rest of the team faster. You will work without close supervision and hold the security and compliance bar our customers require. Nice to have: distributed systems and high availability architecture, regulated-environment security, open-source contributions, experience on remote-first teams.
Join our team: https://job-boards.greenhouse.io/mattermost/jobs/5379251008
*Staff Full Stack Engineer* $172,724 - $227,135 USD Set technical direction for the platform rather than for a feature area: architecture and roadmap across the stack, the standards for how the org uses coding agents, and the strategy for internal tooling and testing. You will influence direction across teams, partner with security and compliance on it, and mentor senior engineers. Nice to have: staff, principal or tech lead experience elsewhere, open-source maintainership, FedRAMP or ITAR familiarity, defense or critical infrastructure background.
Join our team: https://job-boards.greenhouse.io/mattermost/jobs/5405811008

Paramark | Software Engineer (L4) | San Francisco HYBRID (3 days/wk) or REMOTE (US) | Full-time | $199K–$249K + equity
Paramark helps Marketing teams optimize spend across all of their channels and programs. There are proven scientific ways to do this, but they are poorly understood and practiced by only a tiny fraction of teams. Our product ingests data from all of our customers' marketing channels and uses it to train open-source ML models for both measurement and experimentation. This makes it possible for any marketer to use these methods.
In this domain, it's hard to figure out what to build, and it's even harder to be both accurate and simple. You'll be joining a small team -- we have four product engineers. That means owning systems end to end and having real influence over what gets built. Your typical project will start with a high level goal, and you will figure out the rest.
Founded 2023, 15 people, $8M from Greylock and others, cash-flow positive. Reasonable working hours: when the Mercury News covered the return of 996 culture, we were the counterexample. "We don't think early stage startup life requires 18-hour days, or even 12-hour days." https://www.mercurynews.com/2025/08/25/silicon-valley-startu.... 4 weeks PTO plus federal holidays, medical/dental/vision (100% of employee premiums, 50% for family).
Looking for 8+ years, full-stack. Some exposure to statistics, experimentation, or A/B testing helps.
Stack: TypeScript, React, Python, Postgres. Google Cloud, Kubernetes, FastAPI, taskiq.
Process: intro call; technical phone screen; one-day onsite in SF (travel covered for remote candidates)

Overture | Founding President/COO, M&A / Investment Banking | REMOTE (US) | Significant equity
Overture is a vertically integrated, AI-native marketplace for SME acquisitions with listing, valuation, deal rooms, SBA pre-qualification, and capital formation end-to-end. Think TurboTax of business exits, aimed at the baby boomer succession wave (millions of businesses, most with no succession plan).
Who we are: founding team with a decade in fintech, previously backed by Pantera Capital. Platform is close to MVP, pilot structured around ~$5M businesses, fundraise timed to our first deal reaching purchase agreement. In advanced discussions with a top Los Angeles law firm to handle sell-side contracts with one partner already as advisor.
The role: you run sell-side execution on our pilot transactions from engagement through close, and you shape how deal mechanics get productized into the platform. True cofounder: strategy, fundraising presence, significant equity.
You: deep sell-side M&A or IB experience, ideally some in lower middle market ($1M–$25M deals). Comfortable running a transaction hands-on with minimal support. At least one of: fundraising experience, a broker or intermediary network you can bring along, or M&A licensing (Series 79/63 or state broker license a strong plus). Builder's temperament.
Deal supply is our current priority.

As a Senior Security Engineer (Product Security), you will play a significant role in keeping our product safe and secure by building on and maturing Zepto's product security practices. You will work hands-on and shoulder-to-shoulder with Engineering and Product teams, providing guidance and coaching across the software development life cycle while continuing to raise the bar on our security expectations and capability.

Reporting to the Security Engineering Lead, you will work closely with them to develop and build Zepto's product security strategy and approach. You will apply a consultative and advisory approach when working with the wider Zepto team, empowering them to work confidently and to use the self-service capabilities you help establish.
We have excellent working relationships with our developers and we need to keep it that way. We are not the team of no. We are the team that helps make things better.
Zepto is moving quickly towards an AI-native way of building and operating. You will be someone who is already experimenting with AI and agentic tooling, or is genuinely keen to, and who is open to developing the skills to secure these systems as we adopt them. Within the Security team, you are the go-to person for:
Secure development practices Vulnerability management Security architecture advice
Working in a scale-up, means you get the opportunity to flex your skills in a variety of ways. We are agile and always willing to roll up our sleeves to get things done. You can, however, expect your day to day to be involved in the following:
Coach engineering teams and collaborate to ensure every step of the software development life cycle follows security best practices Design, build and maintain security tooling, automation and paved-road controls as production-quality software Conduct security assessments and architecture reviews of Zepto's applications and services Embed within project teams to ensure they are effectively considering information security risk and prioritising security controls Establish and document security architecture and practices in collaboration with the Security Engineering Lead, Product and Engineering teams Work with the Security Engineering Lead to support Zepto's adoption of AI and agentic systems, and experiment with AI tooling to improve how the Security team works Help manage application security incidents in collaboration with the rest of the Security team

You rock backend data pipelines like old jeans: Dagster, Snowflake, DuckDB, Postgres - in the cloud or on your bitchin' VM rack. Docker and Git are second nature. You've embraced agentic coding while still keeping the bots from running the slop show. You play well with others and write code that's easy to live with. Bonus: building AI assistants with PydanticAI, Py2→Py3 migrations, CI/CD and DevOps chops.

Stpkr Technologies | Noida, India (Delhi NCR) | ONSITE | Multiple roles
Stpkr Technologies is hiring for the following roles to build the next generation of wearable devices.
We are currently looking for the following roles but we are also open to interviewing any candidates who feel like they will do their best work here - even if your skillset/experience doesn't fit the current defined roles. Our current team doesn't fit the conventional mold, and we don't expect our future hires will either. If you don't fit the advertised roles, just send us a mail per the same process with whatever job title would fit you the best.
Work is in person near Noida Sector 18, walking distance from Sector 18 Metro Station. We prefer in office work, and for you to be located within Delhi/NCR, Pay is competitive (9-12 LPA), and there are opportunities to earn meaningful equity down the line. We prefer current and recent undergraduates for our roles. If you are still in college we welcome you to apply nonetheless provided you can work as an intern for us in person. Super-flexible overall and all of our current team started out as interns. We are not flexible on in-office work because of operational requirements - please do not apply if you can't relocate/work from office.
Hiring across OS, software, and hardware. AI policy across all roles: you should be able to do the work without AI, and much faster with it.
Systems Engineer - Everything at the OS layer. You've rooted phones, flashed custom ROMs, broken and fixed Linux for fun. Comfortable in C/C++. GitHub with kernel-adjacent or LineageOS-type projects a plus. Stack: Android, Linux, C, C++, Java. Filter: send us something you built where you had to fight the OS or hardware.
Hardware Engineer - Bring-up/Debug/Integration - Take EVT/DVT boards and make them work. Comfortable with J-Link and IDE debugging, reading schematics and reference designs. KiCad/Altium/EasyEDA hobby work would make you ideal. PetaLinux experience or hunger to learn it. ECE undergrad fine. Filter: photo of a board you designed or debugged, plus what went wrong.
Hardware Engineer - Power/RF/Wireless - Make the power and RF paths behave on EVT/DVT boards. Hands-on with schematic capture, layout, soldering, scope/logic analyzer. Given two unknowns, you pick one and start measuring. Filter: sensor fusion work, how noise behaves across protocols, and SPI debug chops.
Founder's Office - Work closely with the founder and the rest of the team to manage the day to day and long term affairs of the company, the Man Friday of the company. Must have a decent degree of technical knowledge (we are a tech company after all) and be efficient at administrative tasks as well as management. Speed and learning ability are prized here, there will not always be a clear path to the work you have to do here, so you will have to figure some of it out on your own.
To apply, contact arnav@stpkr.in with the subject line "HN - Human" and a brief intro for further communication. Attach any documents you deem useful there. Please include the role you are applying for at the top of the email if it is one of the above mentioned, otherwise whatever role fits you best. Shortlisting will be online, interviews will be in person. We are hiring quickly, expect to hear back from us within 2-3 days of applying. If you don't, assume you will not. If you are using an AI agent to mass apply for jobs and we can tell, then you will not hear back. Use an expensive one :P (reiterating this, because we receive so much AI spam now.

THank you, my bad.
howdy! This is the "Who's hiring?" post, I believe you're looking for the "Who wants to be hired?" post
Proxybase | Backend Systems Engineer (Rust) | Remote, Global | Full-Time
Hi HN, I’m the founder of Proxybase [0]. We’re building a SOCKS5 proxy network focused on transparency and ethical sourcing in the residential proxy market. A quick note for anyone who applied last month: thank you to everyone who reached out. We received far more strong applications than expected, and between running day-to-day operations and working through the backlog, we took much longer to reply than we should have. If you applied last month and haven’t heard back yet, I’m sorry for the delay. We’re actively reviewing those applications alongside this new batch.
Why Proxybase? The residential proxy industry has a rough history. Some providers rely on hidden background scrapers bundled into TV firmware or mobile apps, while others use payout systems that can hold provider funds for months.
We’re trying to build something better: Open-source clients: Our GUI [1] and CLI [2] are fully open source, so anyone can inspect and audit what runs on their device. Explicit consent: Providers knowingly opt in. No stealth bundling. Fair, fast payouts: The minimum payout is $1, sent directly to provider wallets in USD stablecoins. We do not hold funds to earn interest on them.
We’re hiring a Backend Systems Engineer with Rust experience to help build:
Asynchronous SOCKS5 routing infrastructure, Daemon and node orchestration, Automated bandwidth-allocation pipelines
Stack: Rust, Tokio, Axum, SOCKS5, Linux systemd daemons, SQLite
Location: Fully remote, async-friendly, flexible time zones Compensation: Competitive salary plus equity. USD or stablecoin payment options are available.
If you’re interested in building infrastructure for an industry that needs better standards, email jobs@proxybase.xyz with your GitHub, résumé, and a short note about what you’ve been working on recently.
I’ll also be around in the comments to answer questions and hear feedback.

Astoria AI | Founding AI Engineer — Agentic Systems | Remote (async) | Full-time | Equity-only pre-seed, $190k-$280k + equity post-seed
Astoria AI is building an agentic runtime for human potential — a suite of specialized AI agents serving candidates and companies across the entire hiring and talent lifecycle: career strategy, networking intelligence, verified matching, compliance-native hiring, onboarding, and retention.
The hiring market is structurally broken: 44% of resumes contain fabrications, ATS filters reject 88% of qualified candidates, and 27% of posted jobs are ghost jobs — while regulation (EU AI Act, Mobley v. Workday, FCRA suits) is forcing enterprises to rethink hiring AI. We're building the fix.
You'll own the intelligence layer: LLM-powered agentic workflows (tool use, structured outputs, multi-step orchestration), RAG/retrieval pipelines, lightweight ML for classification/ranking/entity matching, and evaluation loops for hallucination risk and output quality.
Looking for: 6+ years professional SW engineering (Python/TypeScript/APIs/DBs), hands-on experience with LLM APIs and agentic workflows, and ideally RAG/embeddings/vector DB experience beyond basic chatbots.
Stage: pre-launch, pre-seed, founding team, equity-only until seed round closes (~4-6 months), then competitive salary + refresh grants.
Apply: Konstantin.mueller@astoria.ai with „HN“ in subject, plus resume or GitHub

> Commenters: please don't reply to job posts to complain about something. It's off topic here.
But also: while I didn't post this, that's not uncommon for a founding engineer. They're looking for someone to help start the company from scratch, typically with a healthy dose of equity. It's a calculated risk for the engineer, possibly worth anywhere from zero to a gazillion dollars depending on outcome.
I normally wouldn't comment, but expecting someone with that skillset and those kind of opportunities available to them to work for free for 4-6 months with the promise of actual pay "when our seed round closes" was so egregious I couldn't help myself, sorry.
That's common for founders, though. The CEO and CTO etc. are almost certainly in the same boat. They're not so much saying "come work for free" as "come join this group of us who are taking a leap from our current jobs and building something brand new, in hopes it'll pay off wildly."
It's not typical for founding engineers. It's plausible for a cofounder, with 30%-50% equity.

River (AI voice agents for B2B sales) | New York, NY | ONSITE | Full-time
We build AI voice agents that run live B2B sales calls — real-time voice, browser-driven product demos, automated follow-up. We're pre-seed, backed by the founders of Ramp, Kalshi, and JumpCloud, revenue is on, and demand is already outpacing what we can serve. It's a genuinely fun problem, and we'd love to find the right people to build it with.
We're hiring two founding engineers. To save everyone's time, here's what the role really needs — if a few of these are a strong yes, we'd love to hear from you:
NYC-based and up for working in person (5 days). We're not able to do relocation or visa sponsorship right now. TypeScript/Node as your main production stack — the one you actually ship in day to day. You've shipped real software that real people used — something in production, with revenue, or a startup you built (not tutorials or coursework). You've built something real with LLM APIs. You like owning things end to end — finding the problem and fixing it without waiting for a spec.
Two levels:
Founding Backend Engineer (5+ yrs): real-time/streaming depth (WebRTC, voice, low-latency), plus infra and reliability ownership. Founding Product Engineer (2–4 yrs): frontend-leaning (React/Next.js), customer-facing, CS degree or equivalent standout shipped work.
No need for a formal resume — just send a link to something you're proud of that real people used, and a line on what you owned. We read every one.

New Lantern | https://newlantern.ai | Software engineers (backend and generalist product engineers, founding recruiter) | Full time in San Francisco, CA (ONSITE)
New Lantern is building an AI radiology resident—think Cursor for radiologists. Our application integrates the three software tools radiologists use all day [1], together with AI, to create a platform that saves radiologists toil and lets them focus on reading images and finding disease.
We are a series A startup with ~20 engineers (~40 total staff), have a number of live customers generating revenue, plenty of runway, and are backed by Benchmark, Anthropic, and other great investors. Our customers have told us they would cry if they couldn't use our product anymore.
We're hiring for backend and product engineering, as well as a founding recruiter to help us scale. You'll work directly with our founder/CEO, our staff radiologists, and our end users to build a product that radiologists rely on daily. You'll have real ownership and autonomy, and ship meaningful work frequently.
I'm Steve, New Lantern's Head of Engineering. If you're interested or want to learn more, shoot me a note at (my HN username)@newlantern.ai. I've already hired one engineer from HN this year and interviewed many more!

It would be good to indicate if you are open to engineers in Europe or the UK and what hourly salary they should be expecting. The other locations you list are considerably cheaper and might indicate you aren't paying enough to support talent from these geographies.
