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
