Competitive Programming Expert for AI Model Training

Apply competitive programming expertise to design unique programming problems, reference solutions, and robust test suites that become reinforcement learning environments for training and evaluating next-generation AI models. This remote contractor role focuses on creating and validating complex, competitive-programming style challenges that assess an AI agent''s reasoning and solution correctness. No prior AI experience is required, subject matter and coding skill are what matter.

• Create original competitive programming problems not present on existing online judges, and produce reference solutions.
• Design and implement checkers that correctly handle problems with multiple valid outputs, ensuring accuracy and robustness across edge cases.
• Build comprehensive test suites to validate diverse submissions and corner cases.
• Evaluate and validate participant submissions against complex problem statements, including tasks sourced from platforms like Codeforces.
• Write clear, maintainable C++ code to assess outputs and handle performance constraints.
• Document checker logic and explain intricacies and edge cases in writing and verbally.
• Collaborate with customer teams to refine problem requirements and resolve ambiguities.
• Provide feedback to problem setters and reviewers to improve test cases and checker behavior.
• Stay current with competitive programming standards and incorporate best practices into checker and test development.

• Proven expertise in competitive programming and coding problem analysis.
• Advanced proficiency in C++ for implementing reliable checker solutions.
• Strong analytical skills to interpret complex constraints and multiple valid solution paths.
• Exceptional written and verbal communication skills, able to explain technical details clearly.
• Meticulous attention to detail for code validation and consistent output handling.
• Experience working independently in a remote, collaborative setting, and delivering high-quality, well-documented code under tight deadlines.
• Preferred: prior experience as a problem setter, tester, or checker on major competitive programming platforms.

• Engagement type, contractor.
• Minimum commitment, 15 hours or more per week.
• Location, fully remote.
• Output expectations, experts must meet minimum submission requirements. A minimum weekly task submission requirement applies; the source did not specify the exact number.
• Start timeline, roles are typically filled within 48 hours. If selected, you are expected to begin your first tasks within 24 to 48 hours after completing onboarding.

• Listed rate range, $45 to $65 per hour.
• Primary payment structure, output-based. Experts are paid per task that meets project specifications. The time needed to complete a task varies by experience and workflow.

• No prior AI experience required, domain and coding expertise are the focus.
