Job description

Role Title: Nuclear & Radiological Security Expert

Role Type: Contractor

Location: Remote

Our team 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.
