Competitive Programming Expert - Freelance AI Trainer

About the Role
We connect specialists with project-based AI opportunities for leading tech companies, focused on testing, evaluating, and improving AI systems. Participation is project-based, not permanent employment.
This opportunity involves building competitive programming problems and their automatic graders (test cases + checkers) used to train advanced AI coding models. You'll create problems, write both correct and deliberately-wrong solutions, and design the tough test cases that catch subtly-broken code, ensuring that the training signal is trustworthy. To apply, share your competitive programming handle(s) + current/peak rating, any problem-setting experience, and IOI/ICPC/olympiad history.

What You'll Do

• Write original algorithmic problems — clear statement, sound constraints, an intended solution
• Write correct solutions in C++ and Python
• Write realistic wrong solutions (common mistakes) to test against
• Build and harden test cases: generators, edge cases, stress and
