Math work for AI
AI Training Jobs for Mathematicians
Measured from 79 distinct advertised rates, across 11 platforms. 9 of the 97 open roles here state no hourly rate; 9 advertise only a maximum ("up to $X/hr"), which is excluded.
AI labs pay mathematicians and statisticians by the hour to write hard problems a model gets wrong, grade its step-by-step reasoning and proofs, and formalize proofs in Lean 4 so a computer can check them. 97 roles for mathematicians are open right now on 15 platforms, including Anyone AI, Invisible and Alignerr. Every role is checked against its platform's job board daily.

Before you apply
Most roles start with a timed math assessment, and the best-paid ask for a master's or PhD, or for Lean 4 experience on the formalization roles. Many are posted for one country or ask for a second language, so check the listing before you start. A legitimate platform never charges you to apply.

Frequently asked questions
How much do math AI training jobs pay?
Across the 79 distinct hourly rates posted for roles for mathematicians right now, typical pay runs from $40 to $130 an hour, with a median of $65. The highest posted rate is $200 an hour, at Alignerr. 9 of the 97 open roles for mathematicians state no hourly rate, so check each listing.
Do I need a PhD in math?
Not for every role. The math expert roles ask for a strong math degree and a timed assessment; the research roles ask for a master's or PhD; the proof formalization roles ask for Lean 4 experience. Each listing states the degree and the countries it accepts.
What does a mathematician do in AI training?
You write hard problems with verified solutions that a model gets wrong, grade its step-by-step reasoning and proofs, and formalize proofs in Lean 4 so a computer can check them. It is remote, hourly contract work, and the hours depend on the project.
Are there roles for statisticians?
Yes: statistics and econometrics roles are a list of their own on this page. You check a model's statistical reasoning, experiment design and models, and write the analysis a statistician would sign off on.
Are these jobs legitimate?
They are posted by established AI data platforms (Anyone AI, Invisible, Alignerr and Rise Data Labs among them), and each platform's page here covers whether it is legit, how it vets people and how it pays. A legitimate platform never charges you to apply or to get work.
