Mathematics Expert - (Brazil)

Role overview Create advanced mathematics problems and verified solutions for AI training and evaluation. The work focuses on testing deep reasoning through original, reproducible tasks with one objectively checkable answer.

Responsibilities - Develop challenging problems grounded in mathematical research, modeling, proof, applied, or computational work. - Ensure each problem has a single determinate answer and provide a complete, checked solution. - Explain reasoning clearly and produce technically precise, well-written English materials. - Use Python or other suitable tools to support computational workflows where needed.

Requirements - A master’s or PhD in mathematics or a closely related field. - Research or industry experience in mathematical modeling, proof-based reasoning, applied mathematics, or computational mathematics. - Strong Python skills and familiarity with scientific libraries such as NumPy, SciPy, or pandas. - Understanding of algorithms, numerical methods, and computational approaches. - Ability to create original, difficult problems and communicate technical reasoning with care.

Nice to have - Experience with symbolic mathematics, theorem provers, optimization solvers, or similar tools. - Experience designing olympiad-, graduate-, or research-level problems, or evaluating model reasoning and technical assessments.

Benefits and work setup - Remote, part-time contract requiring about 20 hours per week. - Planned project duration of two months, with potential extension; immediate start indicated. - Compensation listed as up to $40 per hour.
