Remote | Competitive Coder — $45–$65/hour

We are sharing a specialised consulting opportunity for experienced Competitive Coders with strong expertise in C++, algorithmic problem solving, checker development, test design, and competitive-programming evaluation to contribute to an advanced AI training and reinforcement-learning project. Selected professionals will create original competitive-programming problems, develop reference solutions, build robust test suites, and design evaluation environments that test an AI model's ability to solve complex algorithmic tasks. The work requires advanced C++ proficiency, strong competitive-programming judgement, and careful validation of constraints, outputs, and edge cases. No prior experience in AI is required. Key Responsibilities Problem & Environment Design Create original competitive-programming problems not duplicated from existing online judges Define clear problem statements, constraints, expected behaviour, and measurable success criteria Design reinforcement-learning environments for evaluating model-generated solutions Ensure tasks are technically rigorous, deterministic, and objectively verifiable Reference Solutions, Checkers & Testing Develop efficient reference solutions in C++ Design custom checkers, including support for multiple valid outputs Build comprehensive test suites covering edge cases, boundaries, and adversarial scenarios Validate checker behaviour against correct and intentionally flawed solutions Prevent false positives and false negatives in evaluation Algorithmic & Submission Evaluation Analyse solution paths, complexity trade-offs, and alternative algorithms Review participant or model-generated submissions for correctness Identify logical, algorithmic, implementation, and performance issues Evaluate handling of constraints, edge cases, and output requirements Distinguish valid alternative solutions from incorrect reasoning Review & Documentation Review problem statements, checkers, and test cases for ambiguity or weaknesses Provide actionable feedback to problem setters and reviewers Document checker logic, edge cases, and technical decisions clearly Communicate algorithmic reasoning in written and verbal formats Ideal Profile Strong competitive-programming background Advanced C++ proficiency Deep understanding of algorithms and data structures Strong checker and test-case design skills Ability to analyse complex constraints and multiple valid solution paths Excellent debugging, validation, and edge-case analysis skills Strong attention to correctness and output consistency Ability to write clear and maintainable C++ code Strong written and verbal communication skills Comfortable working independently in a remote environment Prior experience as a problem setter, tester, or checker on major competitive-programming platforms is highly advantageous No prior AI-training or model-evaluation experience is required Engagement Details Part-time independent contractor engagement Fully remote Expected commitment: 15+ hours per week Displayed compensation range: $45–$65/hour Actual compensation structure is output-based, with payment made per task that meets project specifications Task completion time may vary depending on experience and workflow Minimum weekly submission requirements apply; the source does not specify the exact number of required tasks Work will involve competitive-programming problem design, C++, checkers, reference solutions, test suites, reinforcement-learning environments, and AI-generated code evaluation Roles are typically filled within approximately 48 hours Selected experts are expected to begin initial tasks within approximately 24–48 hours after onboarding Project scope, task difficulty, algorithms, evaluation criteria, and testing requirements may evolve depending on project needs Work must be completed without using confidential, proprietary, restricted, private-contest, or otherwise protected problem content or source code belonging to any employer, contest platform, client, research organisation, or other third party About the Platform This opportunity is available through 24-MAG LLC.
