AI Evaluator Agreement Calibration Engineer

Sofia Garcia

Full-time · Job · New_York

About the role

Every time we add a new LLM-as-judge to our evaluation stack, its scores disagree with our existing judges just enough to make trend lines meaningless. We publish our benchmark findings internally and expect engineers here to read papers on evaluator calibration and implement what actually works, not just what sounds good in a blog post. In this role you'll build the calibration layer that aligns judge models against human-rated gold sets, so a capability score means the same thing whether it came from judge A or judge C, and report findings back to the evaluation team in a form they can act on.

Responsibilities

  • Build calibration pipelines aligning LLM judges against human gold sets
  • Maintain a growing library of test cases covering judge disagreement patterns
  • Investigate and document root causes of evaluator score drift
  • Share findings on evaluator calibration with the wider research team

Requirements

  • 2+ years working hands-on with LLM evaluation or benchmarking
  • Comfortable reading research on evaluation methodology and applying it
  • Experience with LangChain or similar orchestration frameworks

Benefits

  • Fully remote with flexible hours
  • Internal research time allocated each month
  • Health, dental, and vision coverage
