Responsibilities

  • Design and run experiments to improve model behavior in API and power-user workflows, including function calling, tool use, coding, and planning.
  • Build evals, graders, and environments from real developer and power-user workflows, then convert observed failures into training data, hypotheses, and shipped improvements.
  • Partner with API and power-users to identify high-leverage behavior gaps and translate product signals into post-training interventions.
  • Improve how models behave when composed into systems, focusing on reliable tool use, respecting developer intent, and maintaining coherence across multi-step tasks.
  • Own end-to-end model behavior projects, from qualitative failure analysis through data generation, training experiments, eval design, integration, and launch readiness.
