Competitive Programming Expert - Freelance AI Trainer

About the Role
the company connects 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. In this role, you will be building competitive-programming problems and their automatic graders (test cases and checkers) used to train advanced AI coding models. Your contributions will involve creating problems, writing both correct and deliberately-wrong solutions, and designing tough test cases to catch subtly-broken code. Your work is essential to ensuring the training signal is trustworthy.
