The job description

About the Role

What if your deep knowledge of mathematics could directly shape how AI reasons through the world's most complex problems? We're looking for Mathematics Researchers to help train and improve cutting-edge AI models — designing rigorous problems, evaluating solutions, and pushing AI reasoning to its limits.

This is a fully remote, flexible contract role built for mathematicians who want to do meaningful, intellectually stimulating work on their own schedule. If you hold a Master's or PhD in Mathematics and love the elegance of a well-constructed proof or a cleanly solved problem, this role was made for you.

What You'll Do

Develop, solve, and review advanced mathematical problems with real-world relevance and conceptual depth
Apply your expertise in algebra, calculus, statistics, discrete mathematics, or related areas to design challenging, rigorous problem statements
Evaluate AI-generated mathematical reasoning and outputs for correctness, clarity, and rigor
Collaborate asynchronously with AI researchers and domain experts to improve model performance
Ensure mathematical precision and depth across all deliverables
Work independently on task-based assignments — fully on your own schedule

Who You Are

Holder of a Master's or PhD in Mathematics or a closely related field
Deep expertise in one or more core areas: algebra, calculus, statistics, or discrete mathematics
Experienced with Python, MATLAB, or Mathematica for research or applied projects
Naturally rigorous — you care about correctness, precision, and the quality of mathematical argument
Clear, effective written communicator who can explain complex ideas with accuracy
Fluent in English

Nice to Have

Prior experience with data annotation, data quality, or AI evaluation systems
Background in academic research, mathematical publishing, or technical writing
Familiarity with AI tools or machine learning concepts
Experience working across multiple mathematical subfields

Why Join Us

Work on cutting-edge AI projects alongside leading research labs
Fully remote and flexible — work when and where it suits you
Freelance autonomy with the structure of meaningful, intellectually engaging work
Apply your graduate-level expertise to problems that directly shape the future of AI reasoning
Potential for ongoing work and contract extension as new projects launch
