Overview

As a Codeforces Problem Setter, you will design original competitive programming problems that do not exist on any judge. Your work creates Reinforcement Learning Environments that test a model's ability to solve hard algorithmic challenges. Each task involves writing a problem, a correct reference solution, and a test suite that catches wrong approaches. You will also review other contributors' problems and flag ambiguous cases. This is a remote contractor role requiring 15+ hours per week.

What You'll Do7

Create competitive programming problems that are not found on Codeforces, AtCoder, or other judges.
Write a correct reference solution and verify it against the problem constraints.
Build a test suite with edge cases, maximum constraints, and tests that break plausible wrong solutions.
Implement checkers for problems that accept multiple valid outputs.
Document the intended solution, complexity, and reasoning behind your test cases.
Review problems from other contributors for correctness and test coverage.
Flag problems that are ambiguous or have unintended solutions.

Requirements6

Strong competitive programming record on Codeforces, AtCoder, ICPC, IOI, or equivalent.
Advanced C++ skills for writing reference solutions and checkers.
Deep algorithmic knowledge and 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.

Preferred Qualifications1

Prior experience as a problem setter, tester, or checker on a major platform.

Who Should Apply

Competitive programmers with a strong contest record and advanced C++ skills who enjoy crafting original algorithmic problems. You should be detail-oriented, able to work independently, and available for at least 15 hours per week.

Salary Insight
