BoWatt | Senior Full-Stack Engineer (Go / React) | Remote (Germany) | Full-Time | €70–100k + Equity

BoWatt builds intelligent software for manufacturing complex hardware products — think machines, medical devices, or electronics.

We’re a profitable, bootstrapped startup headquartered in Munich, with team members across Germany and the UK.

We’re looking for a full-stack engineer to own and ship features across our React/TypeScript frontend and Go backend. If you’re interested, you’ll also have the opportunity to work on our AI features.

We’re a team of six, and more than half of us are former startup founders (deep tech, AI, psychedelics and gaming). We build closely with our customers and aim to strike the right balance between moving fast and building things properly.

Reach out directly: fabian@bowatt.com

Looking for your next Builder?

I am available for a contract software engineering position, previously built software at companies like Rippling. Overall 10+ YoE.

Reach out at devhire89@gmail.com , or drop a comment and I'll share details of my previous work. No agencies please.

focal | Head of Technology & Applied AI | Remote/Onsite/Hybrid (US)

focal is an institutionally-backed, next-generation venture firm. Currently investing out of fund II (2025 vintage), we lead at the start, often pre-incorporation, with up to $1M. The next great venture firm won't just use AI. It will be AI-native from the ground up - seeing sooner, deciding faster, and building systems that compound across every founder, deal, and outcome. That's how a 5-person team beats a 50-person firm. We're building that firm. You'll own how it gets built.

This is a long-term, high-impact founding role with meaningful financial upside (carry in funds) and ownership over how the firm is built. You'll join as our 5th team member and partner closely with our GPs in a flat structure.

Your core responsibility: Build and own the AI-native operating system that becomes our structural edge.

Why this might be interesting to you: you get carry in our funds, full ownership over architecture and roadmap, and a problem space that's genuinely unsolved. Venture firms haven't been technically reimagined in decades.

Who you are: A founder-type. A builder: Highly technical, deeply curious, high-output, high-agency. You move from idea → architecture → shipped - fast. You want real ownership over process and outcome, not a seat at someone else's table. You've built things from scratch that worked, and you can point to them.

Comp: carry in our funds (your upside is tied to fund returns), competitive cash, 100% healthcare, 401(k), 6 weeks PTO, 3 months parental leave, budget for compute/tools.

We're not asking for a resume. Send us your LinkedIn (and X if you have it) along with your favorite thing that you've built and tell us why you're proud of it. GitHub, side projects, demos, whatever.

Chestnut | Product Engineers (Backend / Full-Stack) | SF + Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut

Chestnut builds the systems insurance carriers actually run their distribution business on. We replace spreadsheets, legacy vendor systems, and manual processes with real-time data, deterministic workflows, and AI-assisted tooling.

This is end-to-end product engineering.

You won’t just write APIs. You’ll design schemas, build backend logic, ship UI, deploy to production, and handle the sharp edges that show up with real customers. The problems are messy and state-heavy: payouts that must reconcile with finance, onboarding flows with regulatory constraints, dynamic hierarchies, retries, chargebacks, partial failures.

We care a lot about correctness. These systems move real money and cannot drift.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS

We use AI heavily in our workflow — for drafting, refactoring, test generation, and exploring solutions. We expect engineers to use it aggressively. We also expect you to understand what it’s doing, spot when it’s wrong, and maintain strong fundamentals. Taste matters.

You’ll likely thrive here if you: - Have 3–6 years building real product systems - Are strong in at least one typed language and comfortable picking up others - Enjoy owning features end-to-end - Think in terms of invariants, edge cases, and failure modes - Like shipping quickly but cleanly - Want to build systems that operate in production, not demos

We’re a small, high-agency team. You’ll have meaningful ownership and direct impact on customers.

Hybrid in SF and Seattle.

Tetricus Labs | https://www.tetricuslabs.com/ | Full-Stack Engineer (Contractor) | Full-Time | Remote (APAC, UTC+5:30 to UTC+10:00) AND Remote (US)

We're a health tech startup building Personily, a psychiatric care platform that combines structured clinical measurement (PHQ-9, GAD-7, LPFS), passive sensing (sleep, steps, location), AI session transcription, and supervision tooling into a single platform for clinicians and patients.

We're looking for a full-stack engineer who can own features end-to-end across our stack:

- Backend: Python, FastAPI, PostgreSQL

- Frontend: React, Vite

- Infra: Kubernetes, GCP

You'll be building secure, high-performance APIs and clinician-facing interfaces, and taking features from concept through deployment. We're a small team, so you'll have real ownership and work closely with clinicians to shape how the product evolves.

Good fit if you: have strong fundamentals across the full stack, care about security and performance, and are comfortable diving deep into ambiguous technical problems.

We are hiring fully remotely in both APAC and the US, with a HQ in NYC.

Private | Senior Reverse-Engineer | Remote (Global) | Part Time (per project)

I'm and old time programmer, almost retired now, want to stay anonymous here. Will do supervising and project management for this job.

Looking for X86 reverse engineer with good experience of C decompilation, knowning modern tools like Reko, Ghidra, BNinja and such, maybe with AI.

Have a few projects to do, quite esoteric. Can support your own projects for old games or other software. Salary is negotiable per project and agreed KPI, like 50K-100K USDT for around a month-long project.

Weekly progress towards agreed goals is expected, with payments due after results reviews. Mostly async communications. Please mail your free form introduction to mcm10000@gmail.com with words "decompile job" in subject.

Starbridge | Senior Engineers (Kotlin/Java/React/Typescript) | NYC or Remote | Full-time | starbridge.ai

Starbridge is building an AI platform that turns large-scale public and enterprise data into reliable sales insights. We are early, moving fast, and building from zero to one, so this role will have huge ownership and product impact.

Product Engineer: (React/Typescript) who would work closely with product and design to build user-facing parts of the platform. You will craft performant, stable frontends that explain technical concepts to non-technical users and help us iterate fast based on customer feedback.

Backend Engineer: (looking for Kotlin/Java/Scala experience). You'll work across the backend: building enterprise integrations, large-scale scraping and parsing pipelines, and systems that let users apply LLMs to millions of documents to generate insights at scale.

AI Engineer: Applied AI plus strong software engineering. You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini. Expect hands-on Python, ML system design, experimentation, and production reliability. Bonus for RAG depth and frameworks like LangChain, LlamaIndex, or Hugging Face.

We're looking to build our in-person team in NYC but also open to remote!

Apply: https://starbridge.ai/careers and mention HackerNews or email recruiting@starbridge.ai with your resume.

Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US only)

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

RINSE | REMOTE or San Francisco, Los Angeles, Chicago, Boston, New York, New Jersey, Seattle, Austin, Toronto, or Washington DC | Software Engineer | Full-Time | Salary: $80k-$200k USD | https://www.rinse.com

Rinse provides dry cleaning and laundry delivery services to customers in twelve metropolitan areas in the US and Canada. We have sophisticated logistics optimization software, a polished consumer product, and firm business fundamentals. We're now over a decade old - this is a stable, yet consistently growing and innovating, company.

Our engineering team is distributed across the United States and internationally, and has been entirely remote for years now, but a desk can be provided in the above cities if you'd prefer.

We're open to both newly-graduated engineers or more senior engineers, provided they meet our bar. We're particularly interested in true full-stack engineers, with strong React / Typescript / CSS skills to complement comfort in a Python / Django environment. We're also seeking engineers with experience leveraging AI to automate complex operational processes.

We're particularly interested in someone with significant React Native expertise at the moment, as we work to improve the apps our customers, delivery valets, and partners use.

You will join a high-caliber team where collaboration, honesty, and open communication are at the core of everything we do.

Search term bingo: Logistics, Django, Python, Optimization, React, React Native, Postgres, Mobile Engineer, Automation, Delivery, OR-tools, Forecasting

We’re a start-up company, we are building a local-AI camera OS that replaces cloud CCTV: SigmaStar cameras → RTSP/ONVIF → HDMI node → on-device AI (offline-first).

1. Hiring: OS / Device Lifecycle Engineer (Secure Boot / OTA / Identity) (Remote, UK/EU preferred)

We already run RTSP + inference. Now we need the person who owns several year device reality.

You will own (single layer ownership): Secure boot / trust chain (ROM → U-Boot → kernel → rootfs) OTA updates + rollback strategy (A/B, recovery modes) Device identity & lifecycle (provisioning, key rotation) Failure recovery (power loss, corrupted SD, watchdogs)

You must be able to answer directly: SD vs eMMC vs NVMe tradeoffs + corruption mitigation Brown-out behavior, thermal throttling, BSP maturity Camera ISP/NPU concurrency constraints + vendor SDK realities

2. Hiring: Independent Embedded/Firmware Engineer (Bring-up Audit & Stability) (Remote UK/EU preferred)

We’re shipping on real hardware. Reliability beats elegance. We need a senior embedded engineer to audit and validate our assumptions and prevent single-point-of-failure risk.

You will own: Independent review of firmware/bring-up assumptions Validation of performance, thermals, power behavior, stability Reproducible test plans (what breaks, how to detect, how to recover) Documentation that prevents knowledge living in one head

If you’ve shipped embedded systems that survive ugly reality (packet loss, unplugging, thermal throttling, storage corruption), we want to talk.

exe.dev | Full time | SF Bay Area | multiple roles

Support Engineer - If you want to use Claude or Codex (or Shelley!) to trawl through our code base, augmented with (carefully scoped) API keys to make our customers lives better, we are hiring.

Designer - If you want to use Claude or Codex (or Shelley!) to make our product functional and beautiful, we are hiring. You do not ship mocks or assets to other teams. There is no other team. You ship by pushing to production. Don't worry, we've got your back.

Software Engineer - If you see a pattern here, we are hiring. Expect to design, build, and run entire subsystems. What matters is attention to product detail and overall architecture, we have agents for writing code.

With significant industry experience, pay will be over $200,000 with meaningful equity.

We are a small team and going to stay one. The focus is building a high-trust environment. Success for us is if you say "I'm going to fix the load balancer" we all sigh with relief, because you are on it and we can rely on you to take on and solve large projects.
