In this remote, hourly contractor role, you will design complex, challenging mathematics problems intended to test and stretch the limits of advanced AI models, and evaluate how well those models reason through them. Tasks are intentionally difficult and time-intensive, typically requiring three or more hours each to construct, solve, and document fully. Tasks may include:

• Designing original, high-difficulty mathematics problems that probe the boundaries of current AI reasoning, including problems that SOTA models are likely to solve incorrectly
• Developing complete, rigorous solutions and step-by-step reasoning that serve as reference answers
• Evaluating AI-generated solutions for mathematical correctness and reasoning quality, identifying errors in method, conceptual gaps, and weak justification, and explaining corrections clearly in writing
• Rating and comparing AI responses based on correctness, rigor, and adherence to the prompt

Profile Requirements

• Master's degree or higher in Mathematics; PhD strongly preferred
• Deep mathematical expertise with strong command of formal reasoning and proof construction, and the ability to construct novel, non-trivial problems
• Ability to articulate complex mathematical concepts and corrections clearly and accurately in writing
• Full professional English proficiency
• Exceptional attention to detail
• Reliable and self-directed, with consistent output quality on complex, time-intensive tasks in a remote, asynchronous workflow

Preferred Experience

• Prior experience with AI data training, annotation, or model evaluation
• Background in mathematics research, competition mathematics, or academic instruction
