About the job
About typesafe
We’re building prod, not god. TypeSafe is an AI lab pushing frontier model intelligence in a new direction, starting with System One Models. We combine the reasoning of LLMs with the reliability of code, for truly trustworthy AI.
Our first model, Jev, launched in September 2026.
While others chase benchmarks, we’re rebuilding the LLM stack from first principles to make models smarter and also dependable enough to run in production. We’re a small, fast team backed by an $870M Series A led by a16z. Made in SF, with love. Come join the frontier.
About the role
We're looking for scrappy engineers who specialize in frontend and fullstack. You seek joy in beautiful visualization and engaging user interactions - whether it be mobile, webUI or virtual reality. You love fast iteration, you have taste, you don’t stop until it meets your bar.
Our tech stack is primarily Python. We also use TypeScript, Next.js, and Tailwind CSS for frontend. We empower developers to use any tooling they find helpful for getting their job done, including coding agents.
