  • Develop complete mini-repos including a problem statement, reference solution, comprehensive unit tests (10–20 cases), and an executable test runner.
  • Implement clean, production-quality code aligned strictly with test expectations.
  • Write high-coverage tests addressing edge cases, invalid inputs, and performance constraints.
  • Ensure full executability with no missing dependencies, configuration issues, or signature mismatches.

  • 3+ years of backend development experience in one or more of: Rust, C++, C, COBOL, Java, Ruby, PHP, Python, TypeScript, Go, C#, or JavaScript.
  • Familiarity with Docker and basic CI/CD workflows (e.g., GitHub Actions or similar).
  • Strong understanding of clean code, modular design, and performance optimization.
  • Comfortable with Git-based collaboration — PRs, issues, and code reviews.

Role Details

  • High-impact contributions to globally visible open-source projects.
  • Fully remote, flexible engagement.

How to apply for this role
  • Upload your resume — keep it up-to-date and in English. Mercor will auto-fill your profile from it.
