Requirements
- Strong competitive-programming background demonstrated by a public profile, 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 a solution is incorrect and construct an input that breaks it.
- Strong written English at the C1+ level.
- Applicants must provide competitive-programming handles and current or peak ratings, problem-setting experience, and IOI, ICPC, or olympiad history.
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 deadlines and acceptance criteria.
- Paid per accepted task, with rates determined by qualification tier and task efficiency.
