Competitive Coder

About the role

In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. As an expert you will be creating Reinforcement Learning Environments which test an AI model’s ability to solve complex competitive programming problems. You will be tasked with creating a unique custom problem absent from all existing online judges, creating a reference solution and creating a robust test suite.

Responsibilities

• Design and implement checkers for competitive programming problems with multiple valid outputs, ensuring accuracy and robustness.
• Evaluate and validate participant submissions against complex problem statements sourced from platforms like Codeforces.
• Collaborate with the customer's team to fine-tune problem requirements and clarify ambiguous scenarios.
• Develop clear, maintainable code in C++ to assess diverse outputs and edge cases efficiently.
• Document checker logic and communicate intricacies or edge cases in both written and verbal form.
• Provide feedback to problem setters and reviewers on potential improvements to test cases and checkers.
• Stay updated with evolving competitive programming standards and incorporate best practices into checker development.

Requirements

• Expertise in competitive programming and coding problem analysis.
• Advanced proficiency in C++ for implementing robust checker solutions.
• Strong analytical abilities to interpret complex problem constraints and multiple solution paths.
• Exceptional written and verbal communication skills; ability to articulate technical details clearly.
• Meticulous attention to detail in code validation and output consistency.
• Experience working independently in a remote, collaborative environment.
• Commitment to producing high-quality, well-documented code under tight deadlines.

Preferred Qualifications

• Prior experience as a problem setter, tester, or checker on major competitive programming platforms.

Pay

Compensation is output-based; experts are paid per task that meets the project specifications.

Schedule
