$150 per hourAfterQuery Experts
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

- 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

- Fully remote and asynchronous, on your own schedule
