About Mercor: Radiation Safety OfficerCompany: MercorCompensation: $65-$75 per taskCommitment: ContractLocation: RemoteReferral Reward: Earn up to $250 per successful referral.Referral Link: https://t.mercor.com/tcmpZAbout the work
Mercor is assembling a panel of radiological safety 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.
You will:
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 isotope underpins cancer therapy and industrial radiography; the same shielding calculation protects a worker and conceals a source. A model that refuses a routine dose 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.
Background we're looking for
We're looking for people who have held the licence, not just worked under it — the person of record for acquisition, inventory, transfer and disposal. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same shielding calculation protects a worker and conceals a source. 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):
Named RSO on a broad-scope licence — programme management, source inventory, regulatory compliance
RSO or deputy RSO at a university, hospital or research institute running a mixed radionuclide and sealed-source programme
Industrial or irradiator RSO — Category 1 and 2 sealed sources, radiography, gauging, sterilisation
Licensing and compliance specialist — NRC, Agreement State or national regulator submissions, amendments and inspections
Radiation protection manager accountable for ALARA, audits, training and incident reporting across multiple authorised users
What this role demands beyond technical depth
This is writing-intensive work. Every judgment you make needs a written rationale that a non-specialist can follow. Prior technical writing, published research, or expert witness experience is a strong signal; please include a sample or link. You will also be reading and writing about misuse scenarios in your field for sustained periods. We brief experts on this in advance, and you can pause or step away at any point without penalty.
Before you apply
Your work here will not involve, and must not draw on, classified or export-controlled information, or anything covered by an NDA or prepublication review obligation. If you hold such obligations you may still be a good fit; tell us in your application and we will scope the work accordingly.
We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.

Background we're looking for
We're looking for people who have done the measurement and the dose planning themselves, in a facility where getting it wrong mattered — survey, assay, contamination control, work planning. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same shielding calculation protects a worker and conceals a source. 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):
Operational health physicist at a DOE site, national laboratory or reactor facility — survey, assay, contamination control
Internal dosimetry or bioassay specialist — intake assessment, dose reconstruction, committed dose
Decommissioning and D&D health physicist — characterisation surveys, MARSSIM, release criteria
Accelerator or reactor health physics — activation products, neutron fields, shielding design and verification
Dose planning for high-hazard work — RWP development, ALARA reviews, hot-cell and glovebox operations

Background we're looking for
We're looking for people who have assessed how Category 1 and 2 sources actually get stolen, shielded or moved — the security and vulnerability side of a licensed programme, not just its paperwork.

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):
Security or vulnerability assessment of licensed facilities holding Category 1 and 2 sources
Physical protection design and review — detect, delay, assess and respond; insider threat considerations
Source recovery, consolidation or security-upgrade programmes for disused and orphan sources
Regulatory security inspection and compliance — 10 CFR 37 or national equivalents
Transport security for radioactive material — routing, escort, tracking and chain of custody
