Job description

About the role

We\u2019re hiring PhD-level scientists who are proficient bilingual speakers (English & Dutch) based in the Netherlands to help make advanced AI models safer. You\u2019ll apply your scientific expertise to evaluate and strengthen how these models handle specialized technical topics in Dutch as it is spoken in the Netherlands. No prior AI/ML experience is required — we\u2019ll train you on the workflow.

What you\u2019ll do

• Write expert-level prompts in Netherlands Dutch 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\u2019re 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 Dutch as spoken in the Netherlands, plus business-level written English.




• Currently based in the Netherlands. This role covers the Netherlands variety of Dutch specifically; a separate role covers Belgian Dutch.




• 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

• 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.
