About the job
Mindrift, in partnership with toloka-ai, offers project-based freelance roles for mathematics and Python specialists interested in supporting AI development for leading technology firms. This contract position is fully remote and based in Uruguay. All applicants should submit their CV in English and specify their English proficiency level.
Role overview
This freelance role centers on creating and validating advanced computational mathematics problems for AI system evaluation. Each project brings unique challenges, requiring contributors to:
- Develop original mathematics problems that mirror real research workflows
- Design problems requiring Python programming to solve, often using libraries like Numpy, SciPy, or Sympy
- Ensure problems are computationally intensive, not solvable by hand in a reasonable time
- Incorporate complex reasoning across fields such as number theory, combinatorics, graph theory, and numerical analysis
- Draw from real-world research or practical applications in mathematics
- Verify solutions using Python and standard mathematical libraries
- Document problem statements clearly and provide accurate, verified answers
Requirements
- Degree in Mathematics (Pure or Applied) or a related field
- Proficiency in Python for numerical validation; experience with MATLAB, R, C, SQL, Numpy, Pandas, SciPy, or similar tools is also valued
- At least 2 years of professional experience in applied mathematics, research, or teaching
- Background in numerical methods and symbolic computation
- Ability to design problems reflecting authentic mathematical research
- Understanding of computational complexity theory
- Strong written English skills at C1 level or higher
