• 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.
