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 Thai 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 & Thai) 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 Thai. No prior AI/ML experience is required - we'll train you on the workflow.

What you'll do

  • Write expert-level prompts in Thai 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 Thai, 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 Thailand or the wider Southeast Asia 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.
