Responsibilities
- Write original algorithmic problems with clear statements, sound constraints, and intended solutions.
- Write correct C++ and Python solutions as well as realistic deliberately wrong solutions.

- Write testlib checkers and interactors for problems with multiple valid answers.
- Verify that correct solutions pass and wrong solutions fail within time limits.
- Submit accepted project tasks by their deadlines during active project phases.
Requirements
- Demonstrated competitive-programming background through a public profile, Codeforces rating, or IOI, ICPC, or national-olympiad achievement.
- Fluent contest C++ knowledge, including STL and complexity analysis, plus comfort writing Python.
- Ability to explain why a solution is wrong and construct an input that breaks it.
- 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.
- Experience setting or testing problems for contests, using testlib, or creating LLM code-benchmark or evaluation data is preferred.
Benefits
- Remote, part-time, project-based freelance work rather than permanent employment.
- Estimated workload of around 10–20 hours per week during active project phases, without a guaranteed workload.
- Paid per accepted task, with rates based on qualification tier and efficiency, up to the equivalent of $90 per hour.
