Competitive Coder

Build original competitive programming environments that help evaluate and improve next-generation AI systems. You will create complex, real-world coding challenges, reference solutions, and robust test suites that measure an AI model''s ability to reason through difficult problems.

• Create unique custom competitive programming problems that do not appear on existing online judges.
• Develop reference solutions and comprehensive test suites for each problem.
• Design and implement accurate, robust C++ checkers for problems with multiple valid outputs.
• Evaluate submissions against complex problem statements, including those sourced from platforms such as Codeforces.
• Work with the customer team to refine requirements and resolve ambiguous scenarios.
• Write maintainable C++ code that efficiently handles varied outputs and edge cases.
• Document checker logic and communicate technical details and edge cases clearly in writing and conversation.
• Provide feedback to problem setters and reviewers on test-case and checker improvements.
• Apply evolving competitive programming standards and best practices to checker development.

• Expertise in competitive programming and coding problem analysis.
• Advanced C++ proficiency, including building reliable checker solutions.
• Strong analytical ability to interpret complex constraints and multiple solution paths.
• Excellent written and verbal communication skills.
• Meticulous attention to code validation and output consistency.
• Ability to work independently in a remote, collaborative environment and deliver high-quality, well-documented work under tight deadlines.
• Prior AI experience is not required.
• Preferred: experience as a problem setter, tester, or checker on major competitive programming platforms.

• Remote independent-contractor engagement.
• Commitment of at least 15 hours per week.
• Work is output-based and paid per task that meets project specifications. Completion time may vary based on experience and workflow.
• Minimum weekly task-submission requirements apply.

$45 to $65 per hour.

Selected candidates should be prepared to begin their first tasks within 24 to 48 hours after completing the required onboarding steps. This role is currently closed and is not accepting applications.
