Codeforces Problem Setter (English)

You will create original algorithmic challenges for use in AI model evaluation. Your work will turn advanced programming ideas into clear problem statements, verified solutions, and tests that separate correct answers from plausible but incorrect ones.

• Design competitive programming problems that are not already available on online judges.
• Write and validate reference solutions in advanced C++ against stated constraints.
• Build tests for edge cases, maximum limits, and common incorrect strategies.
• Implement checkers when a problem allows multiple valid outputs.
• Document intended solutions, complexity, and the reasoning behind test coverage.
• Review contributed problems for correctness, ambiguity, unintended solutions, and test quality.

This is a fully remote, part-time contractor role. You will work independently and meet deadlines while contributing to AI training and model evaluation.

• Time: At least 15 hours and less than 20 hours per week.
• Language: Clear written and verbal English.
• Skills: Demonstrated competitive programming experience and advanced C++ ability for reference solutions and checkers.
• Knowledge: Algorithms, complexity analysis, constraints, edge cases, validation, and output consistency.
• Work style: Ability to work independently and meet deadlines.
