Nuclear Science & Engineering Expert (AI Safety)

Only for specialist roles: ML research, atmospheric modeling, bioinformatics, COBOL, and audit accounting positions require verifiable credentials, usually a PhD, master's degree, or 5+ years of professional experience. AfterQuery's domain screeners check credentials before confirming an assignment, so listing a degree without the matching experience won't get you through. Generalist reviewer roles have a lower bar but come up less often.

Usually 2 to 3 weeks at 10 to 20 hours a week. AfterQuery re-hires specialists for new projects when AI labs need their field, so plan for it as short, well-paid contracts.

The model already knows the basics. It needs help with hard edge cases, the judgment calls a senior professional in the field gets right.

Tasks are slow and careful. One task can take 45 to 60 minutes of checking citations or calculations, and you're judged on quality more than speed.

You check AI answers to STEM questions, correct their errors and write expert reasoning. As a Nuclear Science & Engineering Expert (AI Safety), you're hired for that judgment, so hands-on STEM experience matters.

This role lists a master's degree. The domain assessment usually matters more, and if you pass it the degree is often secondary. Some platforms check credentials, so list your qualifications accurately.

This role is open only to people based in Australia, Canada, New Zealand, the United Kingdom, and the United States. The limit is usually about where the platform can legally hire, so applying from elsewhere rarely leads to an offer. Check the description for tax or right-to-work rules before you apply, since they can differ by country.
