Bilingual Spanish STEM Expert (PhD) — AI Safety

Official role description

About the role

We're hiring PhD-level scientists who are proficient bilingual speakers (English & Spanish) 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 Spanish. No prior AI/ML experience is required

we'll train you on the workflow.

What you'll do • Write expert-level prompts in Spanish 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 Spanish, 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 Spain 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.
