Description

  • Write original algorithmic problems with clear statements, constraints, and intended solutions.
  • Implement correct reference solutions in C++ and Python.
  • Create realistic incorrect solutions representing common programming mistakes.
  • Develop generators, edge cases, stress tests, and hacking tests.
  • Write testlib checkers, validators, and interactors for problems with multiple valid outputs.
  • Verify that correct solutions pass and incorrect solutions fail within time limits.
  • Meet project deadlines and acceptance criteria for submitted tasks.

Requirements

  • Strong competitive-programming background demonstrated through a public profile, Codeforces rating, or IOI, ICPC, or national-olympiad achievement.
  • Fluent contest-level C++, including STL and complexity analysis.
  • Comfortable writing Python.
  • Ability to explain why solutions are incorrect and construct inputs that expose their flaws.
  • Strong written English at C1 level or higher.
  • Codeforces rating of 1700–2100 for Associate-level work, 2200–2600 for Expert-level work, or 2600+ for Senior/Reviewer work; equivalent olympiad achievement is accepted.
  • Experience setting or testing problems for Codeforces, ICPC, national olympiads, or other online judges (preferred).
  • Experience with testlib checkers, validators, or generators (preferred).
  • Experience creating LLM code-benchmark, reinforcement-learning, or evaluation datasets (preferred).
  • Submit a CV in English, English proficiency, competitive-programming handles and ratings, problem-setting experience, and IOI/ICPC/olympiad history.

Benefits

  • Project-based participation rather than permanent employment.
  • Estimated workload of approximately 10–20 hours per week during active project phases.
  • Paid per accepted task, with compensation up to the equivalent of $90 per hour.
  • Flexible project workflow with qualification, task completion, and payment based on accepted deliverables.
