The team operates with the speed and ownership of a startup, backed by the resources of a leading tech company, and emphasizes shipping production-ready AI systems that make real judgment calls.

Requirements
- Proven experience building, scaling, and supporting production agentic systems, including orchestration, evaluations, guardrails, and failure handling.
- Experience owning a significant technical and product area, with a track record of shipped designs that others have built upon.
- Hands-on coding, architecture review, and debugging of production issues.
- Ability to mentor and unblock other engineers through design patterns and reusable solutions.
- Clear communication of complex technical trade-offs to both engineering and product audiences.
- Ability to translate undefined problems into actionable plans.
- Experience with multi-tenant agent platforms at production scale is a plus.
- Experience building 0-to-1 products or working in startup environments is a plus.
