About the role

Key responsibilities & impact

Ship AI product features that combine engineering and ML.
Build and improve agent workflows (tooling, retries, guardrails, fallbacks).
Improve the latency, cost, and reliability of our systems.
Track what’s new in the AI space (agent teams, methods, tooling) and turn it into shipped products.
Build self-improving loops: systems that run experiments, learn from feedback and evals, and improve the product over time.

Requirements

What you’ll need

Have shipped real systems, not just demos or prototypes.
Have built software with LLMs (structured outputs/function calling, tool use, reliability work).
Have built agents (multi-step workflows that call tools, keep states, and handle failures).
Have set up evals to track quality (tests, regression checks, eval harnesses).
Feel comfortable moving fast, iterating, and owning outcomes end to end.
