Role Title:Nuclear & Radiological Security Expert

Role Type:Contractor

Location:Remote

our partner is engaging Nuclear & Radiological Security Experts to support a customer’s initiative focused on defining standards for nuclear-safety evaluations, information abstraction, and escalation protocols. In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.

Scope of Work

  • Define evaluation scope and standards for nuclear and radiological safety, nonproliferation, and security.
  • Develop frameworks for safe abstraction of sensitive or classified information in technical contexts.
  • Establish robust escalation thresholds and protocols for handling nuclear security risks in research and operational scenarios.
  • Contribute expert guidance on benchmarking nuclear and radiological risk assessments, ensuring effective nonproliferation safeguards.
  • Review, refine, and validate technical guidelines for nuclear/radiological safety in support of advanced-model training.
  • Collaborate with multidisciplinary stakeholders to ensure safety standards protect national and global security interests while enabling legitimate scientific progress.
  • Document best practices and decision rationales for information security and compliance in nuclear domains.

Preferred Qualifications

  • 5+ years of relevant experience in nuclear physics, radiological safety, nonproliferation, or nuclear safeguards (ideally 8–20 years for senior contributors).
  • Advanced degree, professional certification, or equivalent operational experience in nuclear or radiological domains.
  • Proven background with government agencies, national laboratories, regulatory bodies, or academic research in nuclear security or policy.
  • Thorough understanding of nonproliferation frameworks, international safeguards, and weapons-relevant controls.
  • High credibility and recognition in nuclear or radiological safety communities.
  • Exceptional written and verbal communication skills, with the ability to translate complex technical topics for diverse audiences.
  • Experience contributing to or overseeing security evaluations, compliance protocols, or risk assessments within sensitive technical environments.

This is a 100% remote contract role, open to applicants worldwide in the countries the employer accepts.

Pay
At the published rate, 10 hours a week would be about $500–$900 and 20 hours about $1,000–$1,800 before tax. Hours depend on the project, so treat this as a ceiling, not a promise.
Openings
20 openings means this is a high-volume project. You are not competing for one seat: if you pass the test, there is room for you.
Location
Open worldwide in the countries the employer accepts. Payments usually go out through services like PayPal or Wise, so check one of them works in your country.
Credentials
The listing asks for 5+ years of experience. Put it in the first line of your profile: reviewers screen for it before anything else.
Timing
This listing is new today. Projects can close once they have enough people, so it is worth applying while it is open.
Test tips for doctors
  • Lead every review with patient safety: flag dangerous dosing, missed red flags and contraindications first.
  • Cite the guideline you rely on (WHO, NICE, specialty society) when you correct the AI.
  • Keep answers at the level of a specialist colleague, not a patient leaflet, unless the task says otherwise.
