We build the evaluation layer that validates AI agents before they reach customers — an automated system that scores across large volumes of agent traces. You'll own core parts of that platform: the pipeline that runs traces through model-based judges at scale, and the scoring logic that turns raw output into results teams can act on. What you'll do * Design evaluation methodologies and benchmarks for agent reasoning, planning, tool use, reliability, and safety — across LLM-as-a-Judge, trajectory-based, and human evaluation * Take problems from research question to prototype to shipped feature, owning them end to end * Build and harden the pipelines and scoring logic behind customer-facing evaluation * Curate synthetic and real-world datasets; measure the evaluator itself for consistency and agreement with human labels What we're looking for * 5+ years in ML, applied AI,  prompt engineering, agentic AI, including shipping something real to users * Strong Python skills * Practical depth in agentic AI and context engineering: planning, reasoning, memory, tool use, retrieval, long-context * Experience designing evaluation methodologies, not just running evaluations * Hands-on production work with LLM APIs — prompt engineering, structured output, cost and latency tradeoffs * Clear communication with technical and non-technical audiences * Good to have Experience with AI-assisted development tools (Claude code, Windsurf, or similar) Work Personas We approach our distributed world of work with flexibility and trust.
