Veo makes an AI sports camera. One camera on any pitch records the match from several sensors, stitches them into one continuous view, and our models track every player and the ball for the whole game. Coaches and players get stats like goals, possession and passes.
You will build Rust and Python user-space apps on our embedded Linux camera, and help shape the firmware architecture and Linux platform. You won't be writing drivers or doing low-level hardware work. Day to day that means Yocto system services, D-Bus and device trees, BLE/Wi-Fi with GATT and Protobuf protocols to our mobile apps, cloud integrations (REST, S3, OpenTelemetry), and diagnostics across a fleet of devices. You will work closely with our AI, video and cloud teams.
Looking for: 5+ years of experience, fluency in at least two of Rust/Python/C, and experience with embedded Linux (Yocto) and BLE/Wi-Fi. MCU/RTOS experience is a plus.
Our Copenhagen office has an indoor ball court, a rooftop terrace and a gym.
Komodo Health | Principal Product Manager, AI Products | Full-Time | $213k-$288k + equity... | SF/NYC On-site / Remote US
Healthcare in the U.S. is a mess, and most of the data that could help is locked in places nobody can use. Komodo has mapped the patient journey across the country: diagnoses, treatments, providers, payers. Our customers are pharma companies, payers and health systems that want to act on that picture.
We're building the platform that puts it in their hands. There's an AI analyst that works across the whole map. There are apps that turn a population described in plain English into a full report in seconds, and tools that let analysts open, check and rerun the code behind every answer. Underneath all of it is a single query engine that every app and agent shares, so a new product is weeks of work instead of quarters.
Building has gotten cheap. Deciding what to build is the hard part now, and that's the job. We want product managers who:
• Have shipped data, analytics or developer products that people use every day
• Prototype things themselves with AI coding tools, and would rather show a working version than write a spec
• Can sit with a customer, find the problem underneath the request, and say no to the rest
• Write clearly and briefly
Healthcare experience helps, but it isn't required. Curiosity about how the system actually works is.
Small team, real customers, and more leverage per person than I've seen anywhere.

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!

Cardog turns raw vehicle data into facts you can check: VIN decode, market price, recalls, and what the car's own modules report. Insurers, dealers, manufacturers and the public bodies that register vehicles all use it. We're a small team and every engineer owns a whole area.
Data
- Data Platform Engineer (Remote). Own the datasets: government files, manufacturer filings, dealer listings, signals from the vehicle. Decide which source wins when two disagree, and be able to prove it. SQL first, entity resolution, tens of millions of rows. Postgres, TypeScript, Workers, R2.
- VIN Decode Engineer (Remote). Own decode accuracy. Read manufacturer filings line by line, write the patterns, and test them against millions of real VINs. For people who are obsessive about correctness. TypeScript, Postgres.
Design
- Design Engineer (Remote). Own the component library and the screens built on it. Dense data, and making uncertain or missing values look uncertain. You design in the browser and you merge it yourself. React, Next.js, Tailwind.
- Founding Engineer, Dealer Platform (Toronto / Remote). First engineer on software for dealer groups. Time in stores, then ship it the same week. Strong Postgres, multi-tenant.
Business
- Account Executive (Toronto / Remote). Enterprise and public-sector sales cycles measured in quarters. Run technical first calls alone and pull your own numbers in SQL.
- Policy & Standards Lead (Ontario). Represent us in the consultations and standards bodies writing the rules for vehicle data. Closer to counsel than comms.

Come work with me! I'm building out Factory's Security team. Whether you're into pentesting, application and product security, cloud security, corporate security, or compliance, I could use your skills. We recently raised $200M at a $5B valuation and this is an excellent time to join!
MeritFirst helps companies hire on demonstrated ability instead of pedigree. Candidates take realistic work-sample assessments, and employers get a signal they can trust more than a resume. We are backed by 8VC and Slow Ventures.
The hard part is building a signal good enough to influence real hiring decisions: fair to candidates, predictive for employers, explainable, and hard to game.
What you'll build:
- The product candidates use to prove what they can do
- The product employers use to find and hire them, and the scoring behind it
- The engineering bar the next hires will inherit, and helping us hire them
Stack: TypeScript, React, Next.js, Postgres.
We want people who have built and run real production software, debug from evidence, and do not need a fully specified roadmap. Early engineers, technical founders, and senior ICs do well here.
We use AI to move faster and to understand code better, but we do not blindly ship what it writes. You are expected to know and own every line you commit.
Such a cool (and needed) idea. Reminds me a bit of work tptacek et. al. did with starfighters.io to try to solve this in the security domain a while back.
IIRC they hit some challenges that may be relevant to what you're working on. I thought there was a postmortem somewhere, but can't find it just now - only this HN discussion (also looking for it): https://news.ycombinator.com/item?id=37985450
Trustworthy Technology | Earth | Part Time | REMOTE | Anything
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 probably 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.) Geeks are welcome too.
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.
The role is to help set technical direction for how we build and use coding agents at Google: agent infrastructure, making Googlers more productive with agents, and making the agents themselves better.
We’re especially looking for someone who has actually built agentic systems and has experience using them to make software development materially faster in a large engineering organization. This is not primarily a “follow the space” role — we want someone who has shipped these systems, learned what works and what doesn’t, and can use that experience to shape the next generation.
The space is moving very quickly and is competitive both inside Google and externally. We’re looking for someone highly creative who wants to challenge how things are done today, has strong technical judgment, and can turn ideas into working systems with the team.
A big part of the role is not just setting direction, but getting there: prototyping, building, iterating, and inspiring the team to rethink what is possible.

Discord | Senior Software Engineer, Application Security | REMOTE (US West Coast) or San Francisco, CA | $196K-$245K base + equity
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 are hiring a Senior Software Engineer to join the Application Security team. This is hands-on product engineering: building security features that protect user accounts, strengthening authentication and session security, and improving security-critical services. You will work directly with product teams to ship user-facing account security tools and address emerging threats.
Stack: Python primarily, some TypeScript/React, some Rust, occasional JavaScript. Runs on GCP.
Looking for: hands-on AppSec experience (not just compliance-flavored security), comfort reading and writing code across languages, experience shipping production software, and sound judgment on prioritizing real risk over checklist security. Experience with authentication, passkeys, MFA, or session management is especially relevant.
Location: Remote from the US West Coast. If you are in the Bay Area, our SF office is an option. Relocation to the Bay Area is not required.
We're building AI agents to expand access to affordable, and high quality healthcare. We run a vertically integrated primary and urgent care clinic and are actively building an agentic platform focused improving longitudinal care outcomes.

We're building, launching and iterating quickly, and already support more than 10,000 care organisations across 14 European markets, including most of the NHS. We recently raised a $100M Series B to go further, faster.
It started with our AI medical scribe, which listens in to the patient-clinician encounter to generate medical records and saves clinicians 5-10 minutes per patient. Today our AI medical assistant supports clinicians before, during and after each visit, with medical coding and clinical decision support, three products certified as medical devices under EU MDR.
We're expanding our Stockholm team with exceptionally driven builders in a wide range of roles.

VOYGR (YC W26) | Founding Product Engineer | San Francisco | ONSITE | Full-time | $150K-$200K + 0.5%-2.0% equity
I'm Yarik, cofounder and CTO. Before this I spent 20 years in tech with 10+ years running infra, ML and search teams at Google, Meta and Apple.
We love maps and build location/businesses APIs for AI apps and agents. If ChatGPT tells you a restaurant is open and it actually closed in March, that's the problem we fix. We check whether a business still exists, whether its hours and details are right, and enrich it with what's being written about it on the web (news, articles, events). Customers get all of it through one API and we solve it for them with our models which use all available sources and ai voice agents which can confirm the information.
You'd be one of the first engineers. Some weeks that's search and ranking, some weeks it's data pipelines or evals, some weeks it's the API or something a customer asked for yesterday. You'll have a big say in what gets built, not just how.
Stack: Python, FastAPI, Postgres/PostGIS, DynamoDB, Redis, AWS (EKS), our own ML models plus LLM APIs (OpenAI, Gemini, Anthropic).
What I'm looking for:
- 2+ years shipping production systems, or fewer if your background is unusual and you can show what you've built
- real experience with at least one of: search/IR, large-scale data processing, ML systems, API design
- you already use Claude Code, Cursor or similar as part of how you work
- geo/POI data experience is a plus, not required
Fair warning: we are a small team, fast pace, and there could be nights and weekends. If that's not where you are in life right now, totally fine, this just isn't a good fit.
Process: a short note on why you, a 30 min call with me and then Vlad, a technical deep dive, then a paid trial project.

We're looking for a frontend-leaning full stack engineer with a strong eye for design to own the map-heavy parts of our product. That means interactive maps, spatial data explorers and dashboards that city staff use to make decisions.
Stack: React/TypeScript, Python/FastAPI on AWS Lambda, Aurora PostgreSQL + PostGIS. Experience with Mapbox, deck.gl, Leaflet, D3, vector tiles/H3, or nation-scale OSM data is a big plus.
Mid to senior level. Small team, close work with the founders, real ownership.
Process: phone screen, portfolio/design review, 1–2 technical conversations, references, then a chat with our CEO. No LeetCode.
Perks: unlimited PTO, health/dental/vision, $100/mo wellness stipend, team retreats twice a year.

* Work closely with our engineering and product people to feed customer insights back into our product roadmap.
* 5+ years of experience leading sales/GTM in developer tools or B2B SaaS.
* Proven track record closing early-stage technical buyers, engineering leaders, and ops executives.
* High agency and hands-on execution: you love closing deals yourself before building out a team.
* Deep curiosity about AI, autonomous agents, and tool execution ecosystems.
*Stack & Tools:* LI, Apollo, PHONE, Attio, Notion, Slack, plus our own suite of Toolhouse AI workers.
Apply:

Thunder Compute (YC S24) | C++ Systems, Infrastructure, BizOps | San Francisco (Onsite) | Full-time | https://www.thundercompute.com
We're building the VMware for GPUs. Most GPUs in the cloud sit idle a lot of the time because they're bolted to one machine over PCIe. We decouple them.
Our virtualization layer is a userspace shim, loaded through LD_PRELOAD, that intercepts CUDA calls and ships them over the network to a host with a physical GPU somewhere else in the data center. Workloads run unchanged. When a process goes idle, the GPU detaches and gets reassigned, and reattaches in tens of milliseconds when it's needed again. Think Ceph for GPUs: the GPU becomes a network resource a cluster-wide scheduler can pool and pack.
The hard part is making that fast. We're within ~10% of native on most AI workloads, and it lets us serve ~1.8x more users on the same fleet. We run it in production as our own GPU cloud and sell it to enterprises with underutilized fleets.
Team is from Citadel Securities, Aquatic, Old Mission, AWS, and Bain. Series A, $17.5M raised from Matrix and Y Combinator.
Devin (The Devin Experience) | Founding Hardware Lead | Toronto or Boston preferred | REMOTE (North American time zones) | Full-time | Competitive salary + meaningful founding equity | https://experiencedevin.com/jobs
We're building an intimate device that responds in real time to a live AI-generated story and to her body: an app-connected, sensor-equipped vibrator synced to an interactive audio story that AI performs live. The device follows the story, and the story follows her body. Our first 1,000 pre-orders sold out, and we've raised a $1.5M pre-seed. All-woman founding team (CEO is an exited founder and HBS grad; CTO is a multi-time founder and MIT alum; COO/CPO helped lead Wattpad to a $650M exit).
This is employee #1. You'll own hardware architecture, review and change our China partners' schematics and C/C++ BLE firmware (ESP32 / nRF), co-design the BLE protocol under tight latency budgets, integrate the IMU and body sensors (separating real body signals from the device's own vibration), and take us from prototype through EVT/DVT, certification and production, with trips to Shenzhen at key milestones.
You've shipped connected hardware end to end (consumer, wearable, medical or robotics), have 8+ years building hardware products with hands-on embedded work, and have been through at least one production ramp with a contract manufacturer. Bonus: haptics/motor control (ERM/LRA, PWM, waveform tuning), real-time systems, body-worn sensing, FCC/CE/Bluetooth SIG certification.
Apply: email morgan@experiencedevin.com with your resume or LinkedIn and a short note on one product you shipped: what you owned, the hardest hardware problem you solved, and how you knew it worked.
Mozilla / Thunderbird / Thunderbolt | Staff Product Engineer, Enterprise AI | REMOTE (US or Canada) | Full-Time | $185K–$220K USD / $155K–$185K CAD | https://grnh.se/viz7vum71us
We're building Thunderbolt (https://github.com/thunderbird/thunderbolt). We're an 8-person and growing team within the ~60-person company behind Thunderbird, the open-source email client used by 20M+ people.

It's moving from early development into enterprise use cases, and we need someone to own features end to end — concept through launch, adoption, and iteration — not just close tickets.
You'd work full-stack on AI-powered chat, search, research, workflow automation, admin, and integrations. We're looking for 10+ years of engineering experience at Staff scope, hands-on AI product work (LLMs, RAG, agents, retrieval, model/provider abstraction), and comfort in ambiguity — architecture and enterprise requirements are still being defined. Bonus: self-hosted or regulated deployments, EU AI Act / GDPR / SOC 2 familiarity.
Must reside in and have work authorization for the US or Canada. No sponsorship. We read every cover letter - please make it authentic.

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. Featured role this month:
Founding Data Engineer - be our first data hire: make sense of hundreds of millions of rows from vet practice-management systems and our own app, and turn our Postgres and dbt warehouse into a foundation the whole company trusts.
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.

Our mission is to demystify health insurance, healthcare and medical billing. By utilizing cutting-edge technology and advanced data analytics, we deliver personalized recommendations on how to save money, maximize use of plan benefits, stay on top of reimbursements and avoid erroneous or inflated medical bills.
PDT Partners | NYC, Hybrid, 3 days in office
PDT was a pioneer in the field of algorithmic trading in the 1990s and has today risen to become one of the most renowned quant investment companies in the world.
Arrangr is a scheduling platform with tens of thousands of registered users and hundreds of thousands of people reached through scheduling invitations. Calendly is the incumbent, and it's good. Our thesis: booking links make it efficient to fill your calendar, not productive. Every open slot looks identical, so your best hours go to whoever clicks first. Arrangr schedules by importance.
The opportunity: we can see which companies already have several people using Arrangr individually. Each of those is an unmonetized team. You'd build the motion that converts them (in-product surface, sequences, landing page, pilot) and handle the replies it generates: seats, admin rights, security questions. Then reactivate a large dormant base and fix acquisition.
The engagement: five milestones over roughly three months, $12K paid on milestone completion, milestones 1 and 2 contracted first. "Done" means shipped, instrumented and measured against a baseline. Equity is a defined grant tied to new ARR booked; hitting the middle tier triggers a founding title. Engineering time is limited, so you ship within existing product surfaces.
Right for you if you've run PQL-to-team expansion and reactivation against a base in the tens of thousands. Not for CRO specialists (our volume won't support the testing), paid media buyers, or anyone who wants to manage a team. There is no team. You're it.
To apply: no cover letter. Email adams@arrangr.com with three links to things you personally built, one line each on what the numbers did. Plus one answer: we can see which companies have several individual users. How would you turn that into team conversions, and have you run that motion before?
I read and reply to every one. – Adam, co-founder/CEO
We make Fantastical and Cardhop, award-winning calendar and contacts apps for macOS, iOS, visionOS, and Windows. We are a small, fully-remote company spread across the US and Europe, and welcome anyone from around the world. We prefer candidates that are in time zones between US Pacific Time and Central European Time.
We're looking for an enthusiastic and experienced Android developer to help bring the joy of Flexibits apps to Android. This will include learning the ins and outs of Fantastical and bringing its magic to Android, all the way from the natural language parser to the beautiful user interface.
We build serverless applications on AWS for clients and for our own SaaS products. On client projects, we work directly with their developers and help them understand and maintain what we build.
You’ll write backend code in TypeScript/Node.js, build APIs with Lambda and API Gateway, model data in DynamoDB, and design event-driven workflows and integrations. Infrastructure lives in code using AWS CDK, with CI/CD pipelines for builds and deployments. You’ll help decide how systems are designed and take testing, observability and security into account as you build. There’s some React/Next.js work too.
We’re looking for practical experience building AWS serverless applications with TypeScript/Node.js, including infrastructure as code, CI/CD and event-driven design. The role includes working through requirements and technical decisions with clients, so you should be comfortable with that.
We use coding agents daily and expect you to use them too, and to share useful approaches with other developers. AWS serverless development is the main focus of the role.
We’re remote-first, use Scrum, and work with code reviews, pair programming, and unit and integration tests. We meet in person regularly, sometimes in Cologne, sometimes in Austria or Mallorca. We plan travel around family commitments.
You must be based in Germany and speak business-fluent German and good English. We don’t offer visa sponsorship.
€75k–80k, 32 days of vacation, hardware of your choice, and company-paid AI tool subscriptions.
Send your CV to recruiting@pagnos.com – no cover letter needed. Questions before applying are welcome.

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, ~16 people, $8M from Greylock, cash-flow positive. Reasonable working hours: when the Mercury News covered the return of 996 culture, we were the counterexample.

Hedge is an AI-native insurance company. We started as a wholesale brokerage for specialty commercial insurance, where AI agents do most of the work of placing policies: reading messy submissions, chasing missing information, working with 100+ insurance markets, and moving accounts toward coverage. The agents are in production doing real work for paying customers.
We're hiring our founding engineer to own the platform end to end: agents, evals, data pipelines, integrations, and reliability. Python/FastAPI, TypeScript/React, Postgres. You should be deeply technical, resourceful, and have taken something from zero to one. No insurance experience needed.

Shepherd (Series B) | ONSITE | San Francisco, CA & New York City, NY
At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.
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 2 Senior Full Stack Software Engineers, 1 Machine Learning Engineer and 1 AI Product Manager in SF, and 2 Staff Full Stack Software Engineers in NYC. Engineers own projects end-to-end so full stack ability is expected.

From venues and councils to private driveways, our platform makes it simple for drivers to find, book, and pay for parking—while empowering our operating partners to deliver exceptional parking experiences.
Join the JustPark Reporting team. You'll build, ship and maintain the data platform and reporting products behind our venue operations, used at venues like Mercedes Benz Stadium, The Greek Theatre and The O2 Arena. Following the 2024 merger of ParkHub and JustPark, we're scaling internationally, which means distributed systems, teams, and interesting problems at the intersection of payments, data and real time event operations. This is a hands-on engineering role where you'll own meaningful pieces of our platform from design through production, including keeping them healthy on live event days.
We're an AI native engineering team: engineers use Claude Code, Copilot and Cursor as daily tools for code generation, review, debugging and documentation, and we build MCP integrations that connect our AI tools directly to Jira, Confluence, Slack and internal APIs so engineers stay in flow.

-Build financial data flows, including payment processor ingestion, fee reconciliation and ledger backed reporting
-Ingest and reconcile third party data (partner files and payment processor APIs) with idempotent, replayable backfills
-Develop and evolve API and GraphQL serving layers that power our internal and external products
-Migrate existing reporting paths onto the new architecture
We're an early-stage UK company building a mobile application, funded by its founder (just me), which is why the scope below is deliberately narrow.
I'm looking for an applied cryptographer to review a protocol specification before it ships. It is small and specific: three messages, two parties, signature-based, using hardware-backed keys on both iOS and Android. It uses standard primitives only (ECDSA over P-256, SHA-256) and invents no new cryptography; the question is how they are combined. The specification is written and frozen, with test vectors and the generator that produces them.
What I want is a competent second opinion on whether it is sound: six specific questions answered in writing. Not an open-ended audit or a penetration test. The person I'm looking for has either published on protocol security or reviews protocols professionally; being good with crypto libraries isn't quite the same thing.
One piece of contract work, not a role. Under a short mutual NDA.
Email clive@human8e.com by Sunday 4 October with a short summary of the protocol analysis you've done, and I'll send scope, timing and what I'd need from you.
Sidekick Labs | Senior SWE, R&D Engineer, Intelligence Engineer | REMOTE (US Timezones) | Full-time | $170k to $230k Base + Equity + Health
Sidekick builds AI security software for enterprises. Our sensors observe AI behavior and use in situ. From those observations, our reasoning pipeline produces an application inventory and a risk picture, allowing us to provide real-time intervention and coaching right when it matters.
Compensation: base salary scaled to experience, meaningful early-stage equity, and 100% covered health insurance for you and your immediate family
We are a highly senior team. Most of us have been founders or on early founding teams, so we operate with high ownership. We expect you to have a real, current AI-assisted development practice. Our system spans several languages, and we expect you to use AI tools to quickly navigate unfamiliar parts of the codebase so you can comfortably own problems end-to-end across a broad stack.
We are hiring for three roles:
- Senior Software Engineer: You will work across our event-driven architecture. You'll write Go and Python backend services and touch endpoint-deployed browser and desktop components. You need to be comfortable developing in a multi-tenant, microservice-driven SaaS architecture and understand typical scale and security implications for such products.
- R&D Engineer: This is not an open-ended research function. You will take ambiguous feasibility questions tied to our roadmap and return defensible answers inside a week. You'll build handoff-ready prototypes, then shift into engineering mode to personally drive them through to production. You will also define operational envelopes and degradation boundaries, and rigorously deprecate infeasible ideas with documented rationale to avoid future re-litigation.
- Intelligence and Data Processing Engineer: This role is for someone who loves real browser and desktop forensics. You'll use dev tools and debuggers as your primary instruments. Expect to be reading minified code to find where state lives and analyzing network logs to understand undocumented APIs. You will figure out how AI products work and build the prototyping and automation to maintain our software inventory.
To apply:
Send an email to eric+hn@sidekicklabs.com with the role in the subject. Include a PDF of your resume, a quick sentence or two about a tough technical problem you've solved recently, and links to your GitHub, personal site, and/or LinkedIn.
I'm Eric, VP of Technology, and I will personally read every email sent to the HN subaddress. You can view my background here: https://www.linkedin.com/in/three-two-one
Fazeshift | Senior Software Engineer | San Francisco, CA | ONSITE (5 days/week) | Full-time | $200k–$235k + equity
I’m Chris, VP Engineering at Fazeshift. We’re nine engineers plus our Founder/CTO and me, and I’m hiring someone who can help us do more, better: increase both what we can build and the quality and sophistication of the software we build.
Accounts receivable sounds boring until you look under the hood. It sits at the intersection of money, business relationships, software systems of various vintages, and a huge amount of repetitive human work. Instead of giving finance teams another dashboard to stare at, we’re building AI agents that actually do the work across billing, collections, payments, cash application, and the systems connecting them. We’ve grown revenue 12x since 2024, and eight unicorns now run AR on Fazeshift.
A big part of what makes the engineering interesting is that we’re intentionally not the system of record. Our customers already run on ERPs, CRMs, banks, billing systems, payment processors, spreadsheets, and internal software, so we have to understand state across systems we don’t control, act safely in them, and recover when reality disagrees with what an API says should have happened. A timeout doesn’t necessarily mean a write failed. Webhooks can arrive late or twice. A payment may not contain enough information to identify an invoice. In those cases, blindly retrying can be exactly the wrong thing to do.
We use coding agents heavily ourselves. Engineers use Conductor, stacked PRs, Linear, and multiple frontier models every day, with internal skills and tooling that let agents drive and validate our local development environment. We’re especially interested in engineers whose development workflow has already materially changed because of coding agents: people who are comfortable delegating meaningful work, keeping independent threads moving in parallel, debugging where agents get stuck, and improving the surrounding system when the workflow breaks down. But generated code is still your code. Judgment, debugging, systems thinking, taste, and understanding what actually shipped matter more here, not less.
Our development style is roughly: design enough to find the shape of the problem, then build to learn. There’s a short distance here between noticing a problem, deciding what should happen, building it, and seeing the result in production with our customers. You’ll own meaningful problems from ambiguity through design, implementation, rollout, and production, and you’ll work directly with the people affected by what you build.
We’re looking for 5+ years of professional experience, strong TypeScript/full-stack skills, solid systems judgment, and real production ownership. No fintech background needed. Stack: TypeScript/Next.js, tRPC, Prisma/MySQL/PlanetScale, Inngest, AWS.
I read every HN application myself. Email chris.zehner@fazeshift.com with HN in the subject, your LinkedIn/GitHub/résumé, and a few sentences about something interesting you’ve built or improved recently.
Tether | AI Harness Engineer | REMOTE (Worldwide) | Full-time
We're looking for an AI Harness Engineer to build local AI systems combining agentic AI with P2P technology.
Looking for strong JavaScript/TypeScript experience and hands-on work with AI/LLMs, agent harnesses, local inference, and/or P2P/distributed systems. Open-source experience is a plus.
I applied several times, but always got the same generic response. It would be good if you guys gave applicants some feedback, as applying to Tether is not easy. I even had to record a video.
Tough to believe a company run by dudes with close ties to Jeffrey Epstein, having several known fraud charges, would also be pretty shitty in their hiring practices. I’d consider this a bullet dodged, friend.
We're finding the steepest gradients in the economy between model capability and deployed practice. A large part of that work is currently related to software factory construction.
All career stages welcome (including new grads). We are particularly interested in:
* Current/former founders
* High consequence / high criticality technical backgrounds
* Top decile communicators (writing, speech, video) who also make computer go brrr
Roles:
AI Eng - Factory Architect, AI Eng - Commercial, AI Eng - Compounding Leverage, Applied AI Researcher
Veo Technologies | Senior Software Engineer (Rust, Python, C, Embedded Linux) | Copenhagen, Denmark | ONSITE | Full-time
Veo makes an AI sports camera. One camera on any pitch records the match from several sensors, stitches them into one continuous view, and our models track every player and the ball for the whole game. Coaches and players get stats like goals, possession and passes.
You will build Rust and Python user-space apps on our embedded Linux camera, and help shape the firmware architecture and Linux platform. You won't be writing drivers or doing low-level hardware work. Day to day that means Yocto system services, D-Bus and device trees, BLE/Wi-Fi with GATT and Protobuf protocols to our mobile apps, cloud integrations (REST, S3, OpenTelemetry), and diagnostics across a fleet of devices. You will work closely with our AI, video and cloud teams.
Stack: Rust, Python, C, Yocto/OpenEmbedded (meta-tegra), Zephyr, NixOS, GitHub Actions, AWS S3, OpenTelemetry, Grafana, Loggly.
Looking for: 5+ years of experience, fluency in at least two of Rust/Python/C, and experience with embedded Linux (Yocto) and BLE/Wi-Fi. MCU/RTOS experience is a plus.
Our Copenhagen office has an indoor ball court, a rooftop terrace and a gym.

Komodo Health | Principal Product Manager, AI Products | Full-Time | $213k-$288k + equity... | SF/NYC On-site / Remote US
Healthcare in the U.S. is a mess, and most of the data that could help is locked in places nobody can use. Komodo has mapped the patient journey across the country: diagnoses, treatments, providers, payers. Our customers are pharma companies, payers and health systems that want to act on that picture.
We're building the platform that puts it in their hands. There's an AI analyst that works across the whole map. There are apps that turn a population described in plain English into a full report in seconds, and tools that let analysts open, check and rerun the code behind every answer. Underneath all of it is a single query engine that every app and agent shares, so a new product is weeks of work instead of quarters.
Building has gotten cheap. Deciding what to build is the hard part now, and that's the job. We want product managers who:
Small team, real customers, and more leverage per person than I've seen anywhere.If that sounds like you, email our head of product at kaushal.parikh@komodohealth.com Or me at ramraj.velmurugan@komodohealth.com

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!

MeritFirst | Senior Software Engineer | Austin, TX (ONSITE) | Full-time
MeritFirst helps companies hire on demonstrated ability instead of pedigree. Candidates take realistic work-sample assessments, and employers get a signal they can trust more than a resume. We are backed by 8VC and Slow Ventures.
The hard part is building a signal good enough to influence real hiring decisions: fair to candidates, predictive for employers, explainable, and hard to game.
What you'll build:
- The product candidates use to prove what they can do
- The product employers use to find and hire them, and the scoring behind it
- The engineering bar the next hires will inherit, and helping us hire them
Stack: TypeScript, React, Next.js, Postgres.
We want people who have built and run real production software, debug from evidence, and do not need a fully specified roadmap. Early engineers, technical founders, and senior ICs do well here.
We use AI to move faster and to understand code better, but we do not blindly ship what it writes. You are expected to know and own every line you commit.
Start with the assessment: https://www.meritfirst.us/candidate/tests/40bfae94-dbf6-43fd...
Such a cool (and needed) idea. Reminds me a bit of work tptacek et. al. did with starfighters.io to try to solve this in the security domain a while back.
IIRC they hit some challenges that may be relevant to what you're working on. I thought there was a postmortem somewhere, but can't find it just now - only this HN discussion (also looking for it): https://news.ycombinator.com/item?id=37985450
Thanks for what you are doing.
Trustworthy Technology | Earth | Part Time | REMOTE | Anything
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 probably 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.) Geeks are welcome too.
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/ivui3uglp2at3tyltau7jj...
BTW, if/when you join please say hi and let us know what kind of projects you're interested in.
https://trustworthy.technology/ is throwing a 502
Google | Senior Staff Software Engineer, CodeAI | Munich, Germany | On-site
The role is to help set technical direction for how we build and use coding agents at Google: agent infrastructure, making Googlers more productive with agents, and making the agents themselves better.
We’re especially looking for someone who has actually built agentic systems and has experience using them to make software development materially faster in a large engineering organization. This is not primarily a “follow the space” role — we want someone who has shipped these systems, learned what works and what doesn’t, and can use that experience to shape the next generation.
The space is moving very quickly and is competitive both inside Google and externally. We’re looking for someone highly creative who wants to challenge how things are done today, has strong technical judgment, and can turn ideas into working systems with the team.
A big part of the role is not just setting direction, but getting there: prototyping, building, iterating, and inspiring the team to rethink what is possible.

Discord | Senior Software Engineer, Application Security | REMOTE (US West Coast) or San Francisco, CA | $196K-$245K base + equity
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 are hiring a Senior Software Engineer to join the Application Security team. This is hands-on product engineering: building security features that protect user accounts, strengthening authentication and session security, and improving security-critical services. You will work directly with product teams to ship user-facing account security tools and address emerging threats.
Stack: Python primarily, some TypeScript/React, some Rust, occasional JavaScript. Runs on GCP.
Looking for: hands-on AppSec experience (not just compliance-flavored security), comfort reading and writing code across languages, experience shipping production software, and sound judgment on prioritizing real risk over checklist security. Experience with authentication, passkeys, MFA, or session management is especially relevant.
Location: Remote from the US West Coast. If you are in the Bay Area, our SF office is an option. Relocation to the Bay Area is not required.
Interview process: recruiter call, coding round, HM interview, virtual onsite, decision.

I'm Yarik, cofounder and CTO. Before this I spent 20 years in tech with 10+ years running infra, ML and search teams at Google, Meta and Apple.
We love maps and build location/businesses APIs for AI apps and agents. If ChatGPT tells you a restaurant is open and it actually closed in March, that's the problem we fix. We check whether a business still exists, whether its hours and details are right, and enrich it with what's being written about it on the web (news, articles, events). Customers get all of it through one API and we solve it for them with our models which use all available sources and ai voice agents which can confirm the information.
You'd be one of the first engineers. Some weeks that's search and ranking, some weeks it's data pipelines or evals, some weeks it's the API or something a customer asked for yesterday. You'll have a big say in what gets built, not just how.
Stack: Python, FastAPI, Postgres/PostGIS, DynamoDB, Redis, AWS (EKS), our own ML models plus LLM APIs (OpenAI, Gemini, Anthropic).
What I'm looking for: - 2+ years shipping production systems, or fewer if your background is unusual and you can show what you've built - real experience with at least one of: search/IR, large-scale data processing, ML systems, API design - you already use Claude Code, Cursor or similar as part of how you work - geo/POI data experience is a plus, not required
Fair warning: we are a small team, fast pace, and there could be nights and weekends. If that's not where you are in life right now, totally fine, this just isn't a good fit.
Process: a short note on why you, a 30 min call with me and then Vlad, a technical deep dive, then a paid trial project.

City Detect | Full Stack Product Engineer (Design & Geospatial) | Tuscaloosa, AL | REMOTE (US) | Full-time | $110k–$159k + equity

Sensors capture street-level conditions so local governments can find and respond to issues like blight and track how neighborhoods change over time.

We're looking for a frontend-leaning full stack engineer with a strong eye for design to own the map-heavy parts of our product. That means interactive maps, spatial data explorers and dashboards that city staff use to make decisions.
Stack: React/TypeScript, Python/FastAPI on AWS Lambda, Aurora PostgreSQL + PostGIS. Experience with Mapbox, deck.gl, Leaflet, D3, vector tiles/H3, or nation-scale OSM data is a big plus.
Mid to senior level. Small team, close work with the founders, real ownership.
Process: phone screen, portfolio/design review, 1–2 technical conversations, references, then a chat with our CEO. No LeetCode.
Perks: unlimited PTO, health/dental/vision, $100/mo wellness stipend, team retreats twice a year.

Thunder Compute (YC S24) | C++ Systems, Infrastructure, BizOps | San Francisco (Onsite) | Full-time | https://www.thundercompute.com
We're building the VMware for GPUs. Most GPUs in the cloud sit idle a lot of the time because they're bolted to one machine over PCIe. We decouple them.
Our virtualization layer is a userspace shim, loaded through LD_PRELOAD, that intercepts CUDA calls and ships them over the network to a host with a physical GPU somewhere else in the data center. Workloads run unchanged. When a process goes idle, the GPU detaches and gets reassigned, and reattaches in tens of milliseconds when it's needed again. Think Ceph for GPUs: the GPU becomes a network resource a cluster-wide scheduler can pool and pack.
The hard part is making that fast. We're within ~10% of native on most AI workloads, and it lets us serve ~1.8x more users on the same fleet. We run it in production as our own GPU cloud and sell it to enterprises with underutilized fleets.
Team is from Citadel Securities, Aquatic, Old Mission, AWS, and Bain. Series A, $17.5M raised from Matrix and Y Combinator.
Open roles:
- Software Engineer, C++ Systems ($215K-$325K + meaningful equity). Low-level, latency-sensitive work on the virtualization layer. Quant dev / HFT background preferred: https://jobs.ashbyhq.com/thundercompute/2efae53b-817c-43e7-9...

Devin (The Devin Experience) | Founding Hardware Lead | Toronto or Boston preferred | REMOTE (North American time zones) | Full-time | Competitive salary + meaningful founding equity | https://experiencedevin.com/jobs
We're building an intimate device that responds in real time to a live AI-generated story and to her body: an app-connected, sensor-equipped vibrator synced to an interactive audio story that AI performs live. The device follows the story, and the story follows her body. Our first 1,000 pre-orders sold out, and we've raised a $1.5M pre-seed. All-woman founding team (CEO is an exited founder and HBS grad; CTO is a multi-time founder and MIT alum; COO/CPO helped lead Wattpad to a $650M exit).
This is employee #1. You'll own hardware architecture, review and change our China partners' schematics and C/C++ BLE firmware (ESP32 / nRF), co-design the BLE protocol under tight latency budgets, integrate the IMU and body sensors (separating real body signals from the device's own vibration), and take us from prototype through EVT/DVT, certification and production, with trips to Shenzhen at key milestones.
You've shipped connected hardware end to end (consumer, wearable, medical or robotics), have 8+ years building hardware products with hands-on embedded work, and have been through at least one production ramp with a contract manufacturer. Bonus: haptics/motor control (ERM/LRA, PWM, waveform tuning), real-time systems, body-worn sensing, FCC/CE/Bluetooth SIG certification.

It's moving from early development into enterprise use cases, and we need someone to own features end to end — concept through launch, adoption, and iteration — not just close tickets.
You'd work full-stack on AI-powered chat, search, research, workflow automation, admin, and integrations. We're looking for 10+ years of engineering experience at Staff scope, hands-on AI product work (LLMs, RAG, agents, retrieval, model/provider abstraction), and comfort in ambiguity — architecture and enterprise requirements are still being defined. Bonus: self-hosted or regulated deployments, EU AI Act / GDPR / SOC 2 familiarity.
Must reside in and have work authorization for the US or Canada. No sponsorship. We read every cover letter - please make it authentic.

Brilliant.org | Senior/Staff Software Engineer (Interactives) | Remote (North America), SF, NYC | Full-time | $180k-$250k | https://brilliant.org
In a world of cognitive offloading, Brilliant's AI tutor gets kids to actually think. The graphical canvas is interactable by both the learner and their tutor, leading to pedagogically-rich interactions.
We're hiring an interactive-focused engineer to craft the building blocks that power this experience. 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.

Arrangr | Growth Lead, Expansion & Lifecycle | REMOTE | Fixed-fee project ($12K, milestone-based) + equity tied to ARR results → founding role | https://arrangr.com
Arrangr is a scheduling platform with tens of thousands of registered users and hundreds of thousands of people reached through scheduling invitations. Calendly is the incumbent, and it's good. Our thesis: booking links make it efficient to fill your calendar, not productive. Every open slot looks identical, so your best hours go to whoever clicks first. Arrangr schedules by importance.
The opportunity: we can see which companies already have several people using Arrangr individually. Each of those is an unmonetized team. You'd build the motion that converts them (in-product surface, sequences, landing page, pilot) and handle the replies it generates: seats, admin rights, security questions. Then reactivate a large dormant base and fix acquisition.
The engagement: five milestones over roughly three months, $12K paid on milestone completion, milestones 1 and 2 contracted first. "Done" means shipped, instrumented and measured against a baseline. Equity is a defined grant tied to new ARR booked; hitting the middle tier triggers a founding title. Engineering time is limited, so you ship within existing product surfaces.
Right for you if you've run PQL-to-team expansion and reactivation against a base in the tens of thousands. Not for CRO specialists (our volume won't support the testing), paid media buyers, or anyone who wants to manage a team. There is no team. You're it.
To apply: no cover letter. Email adams@arrangr.com with three links to things you personally built, one line each on what the numbers did. Plus one answer: we can see which companies have several individual users. How would you turn that into team conversions, and have you run that motion before?
I read and reply to every one. – Adam, co-founder/CEO

PAGNOS | Cloud Engineer, AWS Serverless (TypeScript/Node.js) | REMOTE (Germany) | Full-time | €75k–80k | business-fluent German required
We build serverless applications on AWS for clients and for our own SaaS products. On client projects, we work directly with their developers and help them understand and maintain what we build.
You’ll write backend code in TypeScript/Node.js, build APIs with Lambda and API Gateway, model data in DynamoDB, and design event-driven workflows and integrations. Infrastructure lives in code using AWS CDK, with CI/CD pipelines for builds and deployments. You’ll help decide how systems are designed and take testing, observability and security into account as you build. There’s some React/Next.js work too.
We’re looking for practical experience building AWS serverless applications with TypeScript/Node.js, including infrastructure as code, CI/CD and event-driven design. The role includes working through requirements and technical decisions with clients, so you should be comfortable with that.
We use coding agents daily and expect you to use them too, and to share useful approaches with other developers. AWS serverless development is the main focus of the role.
We’re remote-first, use Scrum, and work with code reviews, pair programming, and unit and integration tests. We meet in person regularly, sometimes in Cologne, sometimes in Austria or Mallorca. We plan travel around family commitments.
You must be based in Germany and speak business-fluent German and good English. We don’t offer visa sponsorship.
€75k–80k, 32 days of vacation, hardware of your choice, and company-paid AI tool subscriptions.
Send your CV to recruiting@pagnos.com – no cover letter needed. Questions before applying are welcome.

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, ~16 people, $8M from Greylock, 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.

Shepherd (Series B) | ONSITE | San Francisco, CA & New York City, NY
At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.
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 2 Senior Full Stack Software Engineers, 1 Machine Learning Engineer and 1 AI Product Manager in SF, and 2 Staff Full Stack Software Engineers 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.

From venues and councils to private driveways, our platform makes it simple for drivers to find, book, and pay for parking—while empowering our operating partners to deliver exceptional parking experiences.
Join the JustPark Reporting team. You'll build, ship and maintain the data platform and reporting products behind our venue operations, used at venues like Mercedes Benz Stadium, The Greek Theatre and The O2 Arena. Following the 2024 merger of ParkHub and JustPark, we're scaling internationally, which means distributed systems, teams, and interesting problems at the intersection of payments, data and real time event operations. This is a hands-on engineering role where you'll own meaningful pieces of our platform from design through production, including keeping them healthy on live event days. We're an AI native engineering team: engineers use Claude Code, Copilot and Cursor as daily tools for code generation, review, debugging and documentation, and we build MCP integrations that connect our AI tools directly to Jira, Confluence, Slack and internal APIs so engineers stay in flow. You'll work closely with Product, QA, and our UK engineering and data teams to shape the data strategy of a fast growing international company.

Human8e Ltd | Applied cryptographer, protocol review | REMOTE (worldwide) | Contract, fixed fee
We're an early-stage UK company building a mobile application, funded by its founder (just me), which is why the scope below is deliberately narrow.
I'm looking for an applied cryptographer to review a protocol specification before it ships. It is small and specific: three messages, two parties, signature-based, using hardware-backed keys on both iOS and Android. It uses standard primitives only (ECDSA over P-256, SHA-256) and invents no new cryptography; the question is how they are combined. The specification is written and frozen, with test vectors and the generator that produces them.
What I want is a competent second opinion on whether it is sound: six specific questions answered in writing. Not an open-ended audit or a penetration test. The person I'm looking for has either published on protocol security or reviews protocols professionally; being good with crypto libraries isn't quite the same thing.
One piece of contract work, not a role. Under a short mutual NDA.
Email clive@human8e.com by Sunday 4 October with a short summary of the protocol analysis you've done, and I'll send scope, timing and what I'd need from you.
Sidekick Labs | Senior SWE, R&D Engineer, Intelligence Engineer | REMOTE (US Timezones) | Full-time | $170k to $230k Base + Equity + Health
Sidekick builds AI security software for enterprises. Our sensors observe AI behavior and use in situ. From those observations, our reasoning pipeline produces an application inventory and a risk picture, allowing us to provide real-time intervention and coaching right when it matters.
Compensation: base salary scaled to experience, meaningful early-stage equity, and 100% covered health insurance for you and your immediate family
We are a highly senior team. Most of us have been founders or on early founding teams, so we operate with high ownership. We expect you to have a real, current AI-assisted development practice. Our system spans several languages, and we expect you to use AI tools to quickly navigate unfamiliar parts of the codebase so you can comfortably own problems end-to-end across a broad stack.
We are hiring for three roles:
- Senior Software Engineer: You will work across our event-driven architecture. You'll write Go and Python backend services and touch endpoint-deployed browser and desktop components. You need to be comfortable developing in a multi-tenant, microservice-driven SaaS architecture and understand typical scale and security implications for such products.
- R&D Engineer: This is not an open-ended research function. You will take ambiguous feasibility questions tied to our roadmap and return defensible answers inside a week. You'll build handoff-ready prototypes, then shift into engineering mode to personally drive them through to production. You will also define operational envelopes and degradation boundaries, and rigorously deprecate infeasible ideas with documented rationale to avoid future re-litigation.
- Intelligence and Data Processing Engineer: This role is for someone who loves real browser and desktop forensics. You'll use dev tools and debuggers as your primary instruments. Expect to be reading minified code to find where state lives and analyzing network logs to understand undocumented APIs. You will figure out how AI products work and build the prototyping and automation to maintain our software inventory.
To apply: Send an email to eric+hn@sidekicklabs.com with the role in the subject. Include a PDF of your resume, a quick sentence or two about a tough technical problem you've solved recently, and links to your GitHub, personal site, and/or LinkedIn.
I'm Eric, VP of Technology, and I will personally read every email sent to the HN subaddress. You can view my background here: https://www.linkedin.com/in/three-two-one

Fazeshift | Senior Software Engineer | San Francisco, CA | ONSITE (5 days/week) | Full-time | $200k–$235k + equity
I’m Chris, VP Engineering at Fazeshift. We’re nine engineers plus our Founder/CTO and me, and I’m hiring someone who can help us do more, better: increase both what we can build and the quality and sophistication of the software we build.
Accounts receivable sounds boring until you look under the hood. It sits at the intersection of money, business relationships, software systems of various vintages, and a huge amount of repetitive human work. Instead of giving finance teams another dashboard to stare at, we’re building AI agents that actually do the work across billing, collections, payments, cash application, and the systems connecting them. We’ve grown revenue 12x since 2024, and eight unicorns now run AR on Fazeshift.
A big part of what makes the engineering interesting is that we’re intentionally not the system of record. Our customers already run on ERPs, CRMs, banks, billing systems, payment processors, spreadsheets, and internal software, so we have to understand state across systems we don’t control, act safely in them, and recover when reality disagrees with what an API says should have happened. A timeout doesn’t necessarily mean a write failed. Webhooks can arrive late or twice. A payment may not contain enough information to identify an invoice. In those cases, blindly retrying can be exactly the wrong thing to do.
We use coding agents heavily ourselves. Engineers use Conductor, stacked PRs, Linear, and multiple frontier models every day, with internal skills and tooling that let agents drive and validate our local development environment. We’re especially interested in engineers whose development workflow has already materially changed because of coding agents: people who are comfortable delegating meaningful work, keeping independent threads moving in parallel, debugging where agents get stuck, and improving the surrounding system when the workflow breaks down. But generated code is still your code. Judgment, debugging, systems thinking, taste, and understanding what actually shipped matter more here, not less.
Our development style is roughly: design enough to find the shape of the problem, then build to learn. There’s a short distance here between noticing a problem, deciding what should happen, building it, and seeing the result in production with our customers. You’ll own meaningful problems from ambiguity through design, implementation, rollout, and production, and you’ll work directly with the people affected by what you build.
We’re looking for 5+ years of professional experience, strong TypeScript/full-stack skills, solid systems judgment, and real production ownership. No fintech background needed. Stack: TypeScript/Next.js, tRPC, Prisma/MySQL/PlanetScale, Inngest, AWS.
I read every HN application myself. Email chris.zehner@fazeshift.com with HN in the subject, your LinkedIn/GitHub/résumé, and a few sentences about something interesting you’ve built or improved recently.
Tether | AI Harness Engineer | REMOTE (Worldwide) | Full-time
We're looking for an AI Harness Engineer to build local AI systems combining agentic AI with P2P technology.
Looking for strong JavaScript/TypeScript experience and hands-on work with AI/LLMs, agent harnesses, local inference, and/or P2P/distributed systems. Open-source experience is a plus.
Apply: https://careers.tether.io/o/ai-harness-engineer-100-remote-w...
I applied several times, but always got the same generic response. It would be good if you guys gave applicants some feedback, as applying to Tether is not easy. I even had to record a video.
Tough to believe a company run by dudes with close ties to Jeffrey Epstein, having several known fraud charges, would also be pretty shitty in their hiring practices. I’d consider this a bullet dodged, friend.
Diffusion | All | SF Bay (Redwood City) | On site (office!), full-time

There’s a separate „Who wants to be hired“ thread for this
got it
Can't even figure out this forum but he's the best tech+product guy you will get lol
you are right that's why I am broke, i dont deserve it
Try following basic rules first
