About the Role

  • Mercor is partnering with a leading AI research lab to support a Frontier Code Agents project.
  • Contributors help evaluate and improve frontier AI coding models through structured technical assessments.
  • The work focuses on realistic software engineering workflows and model evaluation rather than traditional software development.
  • Spots are limited and filling quickly on a first come, first serve basis.

What You'll Do

  • Use frontier AI coding agents to complete and evaluate complex engineering tasks.
  • Review model-generated code for correctness, quality, maintainability, and performance.
  • Identify bugs, edge cases, and failure modes in model outputs.
  • Compare outputs from multiple frontier models and assess their strengths and weaknesses.
  • Apply professional engineering judgment to realistic backend engineering scenarios.

Time Commitment

Sprint based project that runs in 12-24 hour stretches based on client requirement.

Compensation

  • $400 per accepted task.
  • Typical tasks take approximately 2–3 hours after ramp-up.
  • Compensation is tied to accepted work.

Who Should Apply

  • 2+ years of professional backend engineering experience.
  • Experience building APIs, distributed systems, microservices, backend platforms, or databases.
  • Regular use of AI coding agents such as Cursor, Claude Code, Codex, Windsurf, Gemini CLI, or similar tools.
  • Ability to evaluate model-generated code and identify bugs, edge cases, and architectural tradeoffs.
  • Experience working on large-scale production systems is preferred.
