About the role

Responsibilities

  • Build large evals with real tool calling data, measuring where models suck in long horizon tool execution
  • Work on search problems for finding semantically similar tools and cached tool execution paths and plans
  • Train large agentic harness systems to improve session accuracy with millions of real tool calls as baseline data
  • SFT on agentic traces and RL models on top of agentic harness and app sandboxes

Requirements

  • Independently execute against research goals
  • Prototype and test experiments very quickly
  • Work with product and engineering teams to take research ideas to production in days
  • Strong typing/writing skills: write docs well and explain complex ideas clearly
  • Build trust and admit what you don’t know
