Bilingual French STEM Expert (PhD) — AI Safety - review AI outputs in your specialty
Listed on Mercor as “Bilingual French STEM Expert (PhD) - AI Safety”
What this actually is
You design problems that stump current AI models, evaluate AI reasoning against the correct answer, write rubrics, and provide expert feedback. Often the highest-paid category because the expertise pool is small. The platform title (Bilingual French STEM Expert (PhD) - AI Safety) reflects the rate band and the expertise required, not the day-to-day work.

About the role
We're hiring PhD-level scientists who are proficient bilingual speakers (English & French) to help make advanced AI models safer. You'll apply your scientific expertise to evaluate and strengthen how these models handle specialized technical topics in French. No prior AI/ML experience is required - we'll train you on the workflow.
What you'll do
- Write expert-level prompts in French across specialized scientific topics.
- Evaluate and annotate model responses for scientific accuracy, helpfulness, and appropriate handling of sensitive content.
- Apply structured guidelines to classify prompts and conversations.
What we're looking for
- A PhD in chemistry, biology, or a closely related field - ongoing or completed - with the depth to write prompts across chemical, biological, or radiological and nuclear subject areas.
- Native or near-native fluency in French, plus business-level written English.
- Deep familiarity with modern laboratory and computational techniques in your subfield.
- Sound judgment around scientific safety and the responsible handling of dual-use information.
Nice to have
- Based in France or the wider Western Europe region. This is a preference, not a requirement - applicants based elsewhere are welcome.
- Radiological and nuclear coverage from a chemistry background is welcome - radiochemistry, nuclear chemistry, energetic materials, or radiation physics all qualify.
- Demonstrated depth in a specific subfield rather than broad coverage - for example organic or inorganic synthesis, molecular biology, microbiology, virology, or genetics.
- Research or coursework touching on chemical safety and security, biosafety and biosecurity, or hazardous-materials handling.
- Experience reviewing, grading, or red-teaming technical content.
Project Timeline
- Start date: Immediate
