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

OpenTrain AI is hiring for this role.

• Up to $75 per hour, paid hourly as an independent contractor.

• 100% remote

• Part-time independent contractor

• Flexible schedule

Mathematicians can earn up to $75 an hour writing hard problems and judging AI proofs and computations, with no set schedule.

AI systems now attempt research-level mathematics. Mathematicians build challenging problems from real proofs, formal methods and computational work, then explain where the model's answers are rigorous or wrong.

## What you will do

• Build challenging math problems and scenarios from real proofs, formal methods and computational workflows.

• Review AI answers and explain where they are accurate, rigorous or out of line with mathematical practice.

• Bring sound judgment in numerical analysis, optimization, symbolic computation, proof methods or a core field.

• Write structured feedback that helps the AI improve.

## Who this is for

• A PhD in applied or pure mathematics; applicants with depth in two or more core areas are also encouraged.

• Proven depth in one or more of combinatorics, analysis, number theory, geometry, topology, algebra, numerical analysis, optimization, symbolic computation, or proof and formal methods.

• Strong writing, attention to detail, and clear explanations of complex mathematical ideas.

• Work style: Part-time, contractor work with flexible, asynchronous assignments.

• Fluent in English.

• Helpful: theorem provers such as Isabelle, Coq or Lean, symbolic tools such as Mathematica or SageMath, formalizing proofs, or problems beyond what AI can do today.

## Why this is worth your time

• Earn up to $75 per hour for mathematics review.

• Apply your mathematical depth to real AI evaluation work.

• Flexible, part-time contract work with no minimum hours.

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

## Pay and details

• Up to $75 per hour, paid hourly as an independent contractor.

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