Bilingual Croatian STEM Expert (PhD), AI Safety

$48 - $52 per hour
Part-time

Mercor

About the role

We're hiring PhD-level scientists who are proficient bilingual speakers (English & Croatian) 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 Croatian. No prior AI/ML experience is required, we'll train you on the workflow.

What you'll do

  • Write expert-level prompts in Croatian 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 Croatian, 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 Croatia or the wider Eastern 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.
