AfterQuery builds the expert evaluation data that frontier AI labs use to measure and improve their models. We are hiring radioactive materials and health physics experts as contractors to help make AI models safer in their domain.

What You Will Actually Do

Author prompts and scenarios that probe the boundary between safe and unsafe requests in your field

Review and classify prompts written by other experts as protected or unsafe

Write the domain analysis behind each judgment: why a prompt is acceptable, or where it crosses a line and why

Revise your work based on structured reviewer feedback

Who This Is For

Master's degree or higher in health physics, radiochemistry, nuclear engineering, or a closely related discipline





Citizen of a Five Eyes country: United States, United Kingdom, Canada, Australia, or New Zealand

Physically located in one of those five countries while doing the work

Experience as a radiation safety officer, health physicist, or radiochemist, or in radioactive source or waste management is a plus, not a requirement

Contract and pay

$150/hr equivalent, paid at $85 per approved task

Fully remote and asynchronous, on your own schedule
