Before you apply
This is AI safety work: you test a model, you do not share anything that is classified or controlled. If you hold a clearance or work under export rules, check what you may discuss before you apply, and never bring restricted information into a task. A legitimate platform never charges you to apply.

What does a nuclear or CBRN expert do in AI training?
You probe a model with questions from your field, judge whether its answers are accurate and whether they cross a safety line, and write the reference answers and rules other reviewers grade against. It is remote, hourly contract work, and some of it involves reading hazardous material on purpose.
How do platforms check nuclear and CBRN experts?
Most platforms start with an assessment in your field before any paid work, and each listing says what it asks for. Of the platforms hiring nuclear and CBRN experts now, SuperAnnotate (SME), Mercor, micro1, Sovrano AI and Braintrust run an AI interview (a recorded interview scored by AI) for many roles. SuperAnnotate (SME), micro1, Handshake AI, Braintrust and OpenTrain AI check a government photo ID, usually with a selfie, before you are paid. The section on how each platform checks you quotes each guide with its source.
Are these jobs legitimate?
They are posted by established AI data platforms (SuperAnnotate (SME), Mercor, Invisible and micro1 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.
