Job description We’re seeking a contract Software Engineer - Technical Advisor (6 months, remote) to join a focused evaluation team testing frontier AI coding agents on real production codebases. In this role you’ll analyze full agent sessions, audit model-written pull requests, and build container-based benchmark problems that expose where models fail. You’ll collaborate closely with AI researchers and deliver clear, original technical rationales that pinpoint root causes and boundary-condition gaps.This is an ideal short-term engagement for experienced engineers who enjoy deep code review, reproducible containerized testing, and explaining precisely why a solution is correct or flawed.
