About the Role
Mercor is assembling a panel of nuclear materials and safeguards experts to red-team frontier AI models. The goal is to test whether a model can correctly judge the misuse potential of a technical request — answering legitimate questions fully while refusing genuinely dangerous ones.
What You'll Do
- Write challenging single-turn prompts in your domain, labelled across three levels: benign, dual-use, and adversarial.
- Evaluate the responses that come back against a defined policy standard, and judge whether each was handled correctly.
- Write the reference answer — what a correct response looks like, and the technical reasoning for why.
- This domain lives on the dual-use line more than most. The same material-balance calculation that closes an inspector's account can be used to hide what is missing from it; the same fuel-cycle step that supplies a power reactor is the one a proliferation pathway runs through. A model that refuses a routine accountancy question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.
You're a Good Fit If You
- We're looking for people who have verified nuclear material rather than read about it — inspection regimes, accountancy, and the judgment calls that come with an unresolved discrepancy. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same material-balance figure that closes an account can be used to conceal a diversion. You will be writing prompts that sit exactly on that line, then judging whether the model held it.
- Examples of relevant backgrounds (ideally with red-teaming experience):
- IAEA, Euratom or state-system (SSAC/RSAC) inspector — inspection planning, verification, reporting
- Material accountancy — facility declarations, inventory change reports, MUF evaluation and resolution
- Additional Protocol implementation — declarations, complementary access, information analysis
- Safeguards instrumentation and containment/surveillance — NDA measurement, seals, unattended monitoring
- Safeguards-by-design work or safeguards policy analysis at a laboratory, regulator or ministry
- What this role demands beyond technical depth
