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

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
