Health Physicist - Ai Trainer

$150 per hour

AfterQuery 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
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 safe 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
Contract engagement, no sponsorship available
