Form AI | Full-Stack AI Engineer (Contract) | REMOTE (US) / Austin | https://formai.build

Form is an AI fluency/integration startup for executives & their teams. We build AI applications tailored to how clients work, and need an engineer to do the building.

A typical engagement starts with a client describing a workflow eating their week. You scope alongside them, then build something that makes it disappear. Stack is whatever fits: TypeScript and Python, React or Next.js, Claude and other LLM APIs, integrations with the SaaS our clients use (Notion, Slack, Google Workspace). RAG, agents, prompt engineering, and evals when the work calls for them, not for show.

We're looking for someone who has shipped end-to-end as an early engineer somewhere small, has real opinions about LLM applications, and writes readable code. Comfort scoping with clients and communicating in writing is essential, since most of our work happens that way.

1099 fractional, paid monthly. 10-20 hrs/week, $75-150/hour. 40-hour monthly minimum, scaling with client demand. Potential to convert to a full-time role ($150k-$220k) as the practice grows.

Remote, Austin/US-based. To apply: https://formai.build/jobs or email maya@formai.build.

Red Balloon Security | Security Researchers, Software Engineers | NYC, Northern Virginia | ONSITE, HYBRID | Full-time, Interns (paid) | US Citizenship Required | https://redballoonsecurity.com

We are a team of expert researchers and engineers focused on securing embedded devices. We work with partners across critical industries, and on government-funded research programs (think DARPA). "Full-stack" for us doesn't just stop at back end code; it means being comfortable with operating systems, firmware, and signals going over the wire. You'll succeed here if you are a quick learner who loves working independently on tough, technical problems nobody has ever solved before.

Day-to-day tasks might include:

* Tearing apart a device in our lab, reverse engineering its firmware, and finding security vulnerabilities

* Developing an automated, robotic platform for hardware reverse engineering (custom hardware, vision models, user interfaces, etc.)

* Hooking and patching RTOS kernel functions to execute defensive device integrity validation code, without violating real-time requirements

* Building scalable servers for processing millions of device telemetry messages across thousands of concurrent connections

* Maintaining open-source reverse engineering tools (like OFRAK https://ofrak.com) and cooking up fun demos for hacker conferences (like this web game we built for DEF CON in 2023 https://ofrak.com/tetris/)

Our main office is in Manhattan, but we are building out a new office in Northern Virginia. US citizenship required. Bonus points if you have an active security clearance, or are willing to get one.

Be sure to mention Hacker News in your application.

vvd | Design Engineer | Remote (work from anywhere) | Full-time | React, TypeScript, Next.js

https://vvd.world

We’re building tools for storytellers, worldbuilders, writers, and creators.

We’re looking for a Design Engineer who can design and build polished product experiences end-to-end. You should care deeply about taste, interaction, motion, and frontend craft, but also understand enough about APIs, auth, and data flow to avoid getting blocked.

We’re AI-native, but not trying to replace human creativity. We use tools like Cursor and Claude Code as leverage to move faster while keeping a high quality bar.

Strong fit if you’ve shipped real things, can go from rough idea to polished implementation without waiting for perfect specs, and have built interfaces that feel good, not just functional.

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

We make robots that autonomously construct buildings. We are currently developing and manufacturing our autonomous bricklaying system in the beautiful centre of Amsterdam. And our robots are already earning real revenue operating on construction sites all over the Netherlands.

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 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!

Chestnut | Senior Product Engineer | SF or Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut

I'm Nick, CTO & co-founder. We're Rippling, but for insurance carriers paying their sales force. Every policy sold triggers a chain of payouts across brokers, agents, and sub-agents. Today that runs on spreadsheets and legacy vendor systems and tomorrow they'll run on Chestnut. Nationwide and other major carriers have already made the switch.

Revenue is up 8x in the last year. We're backed by a16z. Founding team came out of leadership at Ethos (insuretech that recently IPO'd in January).

The work is state-heavy and correctness-critical: payouts that must reconcile with finance to the cent, dynamic agent hierarchies, retries, chargebacks, partial failures. These systems move real money and cannot drift.

You'll design schemas, build backend logic, ship UI, deploy, and own the sharp edges that show up with real enterprise customers.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS. We use AI aggressively and expect you to as well.

We're looking for 3–6 years on real product systems. You're thoughtful about invariants and failure modes.

Apply: https://jobs.ashbyhq.com/Chestnut

IBM Research | Boston, MA, USA (hybrid - 3 days in office; location flexibility - Boston preferred but NYC/SF possible) | Research Scientists and Research Engineers

Our team thinks there's a lot of value in co-design of software harnesses and LLMs, particularly for small/medium models, particularly in the open model space.

Our colleagues across the isle do an awesome job at training the Granite model series, so we (physically and organizationally) sit in a uniquely good place to do impactful work in this space.

I am currently looking for early career scientists and engineers who are interested in LLMs and also one of {programming languages, formal methods, compilers}. Experience with Rust is a plus. Cool systems-y projects with formalizations on paper or in rocq/lean/etc also a plus. Neither is necessary, per se.
