Radiological Source Security Specialist

What You'll Do6

• Write single-turn prompts from your radiological security background and label each one benign, dual-use, or adversarial.
• Test model outputs against the stated policy standard and decide if each response handled the request in the right way.
• Draft the reference answer for every prompt, including the technical basis for the judgment.
• Explain your calls in plain language so a reader without radiological training can follow the reasoning.
• Review misuse scenarios in your specialty across long writing sessions, with breaks allowed when needed.
• Flag any prompt or response that touches on information you cannot discuss due to NDA, export control, or prepublication review.

Requirements9

• Hands-on work assessing how Category 1 and 2 sources can be stolen, shielded, or moved within a licensed programme.
• Ability to separate a routine professional question from one that seeks harmful operational detail.
• Experience with physical protection design or review, including detect, delay, assess, and respond tactics and insider threat factors.
• Background in source recovery, consolidation, or security upgrades for disused and orphan sources.
• Knowledge of regulatory security inspection and compliance, such as 10 CFR 37 or a national equivalent.
• Familiarity with transport security for radioactive material, covering routing, escort, tracking, and chain of custody.
• Strong technical writing, published research, or expert witness work, with a sample or link ready.
• Red-teaming experience is a plus, including work against AI models or in security vulnerability assessments.
• No reliance on classified, export-controlled, NDA-covered, or prepublication-review material; disclose any such obligations.

Who Should Apply

Ideal candidates have assessed real Category 1 and 2 source security, not just filled out compliance paperwork. You can read a technical request, spot when it crosses from training or safety into theft, shielding, or movement planning, and defend that call in writing. A background in physical protection, source recovery, transport security, or 10 CFR 37 inspections fits well, and prior red-teaming or model evaluation helps. This role suits specialists who enjoy sustained writing about misuse scenarios; it is less suitable for generalists, policy-only reviewers, or anyone who cannot share a writing sample. Applications often score low when the candidate lists broad regulatory knowledge without concrete source security work, or when they skip the required writing sample and rationale example.
