• Expertise: Practical experience in numerical methods, optimization, statistics, mathematical modeling, or scientific computation.

About AI training work

AI training is the human work behind systems that learn from examples, including writing, testing, and evaluating model outputs. This role uses specialized mathematical and programming knowledge to create reliable evaluations that show whether AI agents can solve computational problems correctly.
