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.

Compensation Structure

Compensation is output-based; experts are paid per task that meets the project specifications. The time required may vary depending on your experience and workflow. Minimum submission requirements apply.

Start Timeline & Availability

We typically fill roles within 48 hours and are looking for experts ready to jump in right away. If selected, we expect you to start your first tasks within 24–48 hours of completing onboarding.
