  • Write testlib checkers and interactors for problems with multiple valid answers.
  • Verify that correct solutions pass and incorrect solutions fail within time limits.

Requirements

  • Demonstrated competitive-programming background through a qualifying Codeforces rating or IOI, ICPC, or national-olympiad record.
  • Fluent contest C++ skills, including STL and complexity analysis, plus comfort writing Python.
  • Ability to explain why solutions are incorrect and construct inputs that expose their flaws.
  • Strong written English at C1+ level.
  • Applicants should provide competitive-programming handles and current or peak ratings, problem-setting experience, and IOI/ICPC/olympiad history.
  • Preferred qualifications include contest problem-setting or testing, Testlib experience, and experience creating LLM code-benchmark or reinforcement-learning evaluation data.

Benefits

  • Remote, part-time, project-based freelance work rather than permanent employment.
  • Estimated workload of approximately 10–20 hours per week during active project phases, with no guaranteed workload.
  • Payment is per accepted task, with compensation up to the equivalent of $90 per hour depending on qualification tier and efficiency.
