Responsibilities

  • Evaluate AI-generated coding interactions end-to-end.
  • Assess whether agent responses are useful, correct at a high level, and aligned with strong engineering judgment.
  • Evaluate the quality of explanations, preambles, and reasoning—not only syntax or code correctness.
  • Distinguish between different levels of response quality and provide clear feedback on what worked, failed, or felt misleading.
  • Help define what excellent interactions look like when using coding tools such as Cursor.
  • Judge whether agent interactions guide users effectively and build developer trust.

Requirements

  • Staff/Principal-level software engineer or equivalent experience.
  • Strong background in TypeScript, JavaScript, or Python.
  • Hands-on experience using OpenAI Codex, Claude Code, and Cursor.
  • Deep familiarity with modern AI-assisted development workflows.
  • Ability to evaluate code without fully executing or deeply reviewing every line.
  • Comfort providing direct, opinionated feedback and making subjective but rigorous judgments.
  • High standards for engineering quality.
  • Experience with Cursor or similar AI-first IDEs is preferred.
  • Prior exposure to prompt design or evaluation workflows is preferred.
  • Experience mentoring senior engineers or defining engineering standards is preferred.

Benefits

  • Start ASAP.
