Responsibilities

  • Evaluate the quality of interactions with modern coding agents such as OpenAI Codex and Claude Code
  • Assess whether AI-generated responses make sense and whether preambles and reasoning are useful
  • Judge whether outputs demonstrate strong engineering judgment
  • Evaluate AI-generated coding interactions end to end
  • Determine whether outputs are useful, correct at a high level, and aligned with strong engineering practice
  • Assess explanations and reasoning, not just code
  • Distinguish between different levels of response quality
  • Provide clear, opinionated written feedback on what worked, what did not, and what felt misleading
  • Help define what excellent interaction quality looks like for Cursor, Codex, and Claude Code
  • Record short video explanations of evaluations
  • Complete a take-home evaluation exercise before starting

Requirements

  • Senior, Staff or Principal-level engineer (or equivalent experience)
  • Strong background in TypeScript/JavaScript or Python
  • Hands-on experience with at least one of OpenAI Codex, Claude Code or Cursor
  • Deep familiarity with modern AI-assisted development workflows
  • Ability to evaluate code without executing it or reviewing every line
  • Strong written and spoken English (B2 or above)
  • Ability to write detailed feedback and record short video explanations
  • Comfortable giving direct, opinionated feedback
  • High standards for engineering quality
  • Prior exposure to prompt design or evaluation workflows is nice to have
  • Experience mentoring senior engineers or defining engineering standards is nice to have
  • Must clear a take-home evaluation exercise with a recorded Loom walkthrough
  • Must agree to a simple background check for the project

Benefits
