The work

As a Mathematics LLM Evaluation Expert, you will help assess how well AI systems solve advanced mathematics problems. You will work with model-generated solutions, computational tasks, and formal proofs.

Your work will cover mathematics from early undergraduate through doctoral level and require clear written reasoning, careful review, and precise feedback.

  • Design challenging mathematics problems that test multi-step, abstract, and proof-based reasoning.
  • Solve problems independently and write logically structured solutions with clear justifications.
  • Review AI-generated solutions, find mathematical errors or missing arguments, and provide corrections and annotations.
  • Create and validate Python solutions using approved scientific libraries.
  • Translate mathematical problems and proofs into Lean and check that the formal proofs compile correctly.
