Evaluate and debug AI coding-agent outputs to sharpen Cohere's models
Cohere is hiring a part-time independent contractor (16+ hrs/week, Canada-based, 12-month contract) to review and debug code, navigate repository architecture, and analyze coding-agent trajectories for model training and evaluation. The role wants 3-5 years of software engineering experience with proficiency across Python plus Java, JavaScript, Go, and SQL, prior API design/build/deploy experience, and ideally hands-on exposure to code agents like Claude Code, Cursor, Codex, or OpenCode — this is evaluation/annotation work, not product engineering.

Likely format
Initial resume/writing-sample screening, then a virtual annotation test (coding take-home + writing sample), then a video screen with the Operations team, then offer.
What this interview tests
- Multi-language code review (Python, Java, JavaScript, Go, SQL)
- Debugging and evaluating AI-generated code / agent trajectories
- API design critique
- Repository architecture navigation
- Precision and rigor in labeling/evaluation judgments
Common question themes
Review this code snippet or diff and identify what's wrong with it
Walk through evaluating whether a coding agent's trajectory actually solved the task correctly
Critique an API design — what's missing or wrong given the stated requirements
Describe a time you caught a subtle bug that looked correct on the surface
How do you navigate an unfamiliar codebase quickly to assess whether a change is sound
What's your experience using coding agents like Claude Code, Cursor, or Codex, and where have you seen them fail
