About this opportunity
Audit how frontier AI models answer nuclear and radiological questions: classify the request, judge each answer, rank them, and write the one the model should have given. Remote, hourly, first batch about 10 hours. For nuclear professionals with three or more years in the field.
Required skills
- Nuclear physics
- Reactor physics
- Health physics
- Radiation safety
- Dosimetry
- Nonproliferation
- Scientific review
- AI safety review
- Professional English
What you'll do
- Classify each user request as benign, dual-use or adversarial, and say what puts it in that category.
- Judge each of the three model answers as safe or unsafe, with the reasoning written out.
- Rank the three answers against each other on accuracy, safety framing and usefulness.
- Write the reference answer, including where the right response is a partial answer with a clear boundary.
- For dual-use requests, set out the legitimate use case and who should be able to get an answer.
- Catch physics errors that read fluently: wrong cross sections, bad decay chains, misapplied shielding logic, dose calculations that do not hold.
- Flag unjustified refusals on routine professional questions.
- Apply the project rubric consistently and escalate the cases it does not cover.
Requirements
- Degree in nuclear engineering, reactor/nuclear physics, health physics, radiochemistry or closely related
- Minimum 3 years of professional experience in the field
- Based in the US, UK, Canada, Australia, New Zealand or the European Union
- English at C1 or above, written and verbal
- Passes the expert survey before a bootcamp seat is allocated
- Available for the paid bootcamp on Monday and production from Tuesday
- Able to commit roughly 10 hours inside the first batch window, closing Sunday
- Joins the Sovrano Discord before the bootcamp
- Independent contractor, invoices Sovrano directly
Preferred qualifications
- Hands-on work with MCNP, GEANT4 or comparable transport codes, or with nuclear data libraries.
- Safeguards, export control or nonproliferation assessment experience.
- Prior AI red-teaming, evaluation or annotation work.
