About the position We create high-quality STEM training data for frontier AI models. Our data is used directly in training and evaluation pipelines at leading AI labs to improve model reasoning in technical domains. We are looking for experts in Mathematics to design rigorous, deterministic problems that are genuinely challenging for state-of-the-art AI systems. Each problem must have exactly one verifiable correct answer and be submitted together with a complete, verified solution.

Responsibilities

• Design advanced mathematical problems for frontier AI training and evaluation
• Create deterministic problems with exactly one correct answer
• Write complete, verified solutions and clearly document the reasoning process
• Develop problems that test deep mathematical reasoning, not just memorization
• Ensure all outputs are technically precise, reproducible, and well-written in English Requirements
• PhD Students or Graduated PhDs in Mathematics or a closely related field
• Strong research or industry experience involving mathematical modeling, proof-based reasoning, applied mathematics, or computational mathematics
• Ability to design original, difficult problems that mirror real mathematical workflows
• Excellent attention to detail and technical writing skills in English Nice-to-haves
• Background in olympiad-level, graduate-level, or research-level problem design
• Experience evaluating model reasoning, benchmarking, or technical assessment design Apply To This Job
