About the Role
We're looking for a full-stack engineer with strong technical fundamentals and exceptional product taste. The role is ideal for someone who enjoys owning features end-to-end, building at the frontier of research and engineering, and making high-impact contributions to the business.
You will own the entire feature development lifecycle and spend roughly 70% of your time on the backend and 30% of your time on the frontend.
You will work on things like: expanding the capabilities of RL environments, building agentic harnesses, deploying agents to real users and iterating on feedback, designing product features for evaluating models and analyzing their failures, creating synthetic data platforms.
You will move fast, ship often, talk to researchers or power users of AI agents, and solve ambiguous problems that no one has solved before.

Frontend: TypeScript, React, DuckDB
Infra: AWS, Modal, Kubernetes
