Mathematics Expert, Part-Time AI Math Task Validation - Remote (United States)

Mathematics Expert, Part-Time AI Math Task Validation - Remote (United States)

• $60–$120 per hour equivalent, paid per accepted task

• 100% remote

• Part-time

• About 15 hours a week, you choose when

AI systems get better at mathematics when experts check both their reasoning and their numbers.

AI training is the human work behind AI systems that learn from worked examples. Teams building these systems need mathematicians who can write and solve hard problems, check each step, and confirm the results with Python and scientific software. Your checks help test whether AI-generated mathematical solutions are correct and reproducible. This is remote, part-time contractor work applying your mathematical expertise to AI training.

What you'll do

• Write, solve and review advanced mathematical tasks used to train AI systems

• Turn mathematical requirements into precise procedures and implement them with Python and command-line tools

• Automate calculations, numerical experiments, parameter sweeps and visualizations, then check the results

• Test special cases and confirm that results are mathematically sound, numerically correct and reproducible

Why this is worth your time

• Earn $60–$120 an hour equivalent while solving and checking advanced mathematical tasks

• Work on AI systems as they learn to reason through mathematics, checking their solutions step by step

• Put Python and scientific software to work on well-defined mathematical problems

• Fully remote and flexible, no fixed shifts, no commute

Who this is for

• Fluent in English

• MS or PhD in Mathematics, Applied Mathematics, Statistics or Operations Research, or in Computational Science, Theoretical Computer Science or another closely related quantitative field

• Or a BS in Mathematics or a related quantitative field, plus 1 to 2 years of professional or research experience focused on mathematics

• Strong expertise in at least one area: applied mathematics, numerical analysis, optimization, probability or statistics, or discrete mathematics, algebra or geometry, or mathematical modeling or dynamical systems

• Practical Python experience in mathematical computation, automation, experimentation or validation

• Familiarity with scientific tools such as NumPy, SciPy, SymPy, SageMath and CVXPY, or pandas, Matplotlib, Jupyter, Julia or GNU Octave, numerical solvers or comparable software

• Helpful background includes command-line mathematical tools, optimization libraries, numerical methods, scientific computing, or reproducible computational research.

• No AI experience needed. You bring the expertise; you create, solve and validate the mathematical tasks.

Pay and details

• $60–$120 per hour equivalent, paid per accepted task as an independent contractor

• Part-time, flexible schedule; fully remote, United States
