Job Title: Codeforces Problem Setter Job Type: Contractor (15hrs+ a week) Location: Remote
Opportunity Snapshot
Pay: $30 - $100 Commitment: 15+ hours per week Location: Fully remote You’ll need: Strong competitive programming background and advanced C++ Your tasks: Create original competitive programming problems with reference solutions and robust test suites You’ll create Reinforcement Learning Environments that test a model’s ability to solve hard algorithmic problems. Each task means writing an original problem that doesn’t exist on any online judge, a correct reference solution, and a test suite strong enough that a wrong solution fails.
What you’ll do
- Design original competitive programming problems, absent from Codeforces, AtCoder, and all other judges.
- Write a correct reference solution and verify it against the constraints.
- Build a robust test suite: edge cases, maximum constraints, and tests that break plausible wrong approaches.
- Implement checkers for problems with multiple valid outputs.
- Document the problem’s intended solution, complexity, and the reasoning behind your test cases.
- Review problems from other contributors for correctness and test coverage.
- Flag problems that turn out to be ambiguous or have unintended solutions.
What we’re looking for
- Strong competitive programming record — Codeforces, AtCoder, ICPC, IOI, or equivalent.
- Advanced C++ for reference solutions and checkers.
- Deep algorithmic knowledge and the ability to reason about constraints, complexity, and edge cases.
- Meticulous attention to detail in validation and output consistency.
- Clear written and verbal English for documenting problems and edge cases.
- Comfortable working independently and meeting deadlines.
- Prior experience as a problem setter, tester, or checker on a major platform is a strong plus.
