Responsibilities
- Develop and maintain the physical protection design and Design Basis Threat (DBT) assessment for our lead-cooled fast reactor
- Identify and classify vital areas, target sets, and security-related structures, systems, and components in line with defense-in-depth principles
- Design physical protection systems — detection, delay, and response — and perform vulnerability and path analysis against the applicable DBT
- Support graded-safeguards categorization of HALEU fuel (typically Category II or III) and coordinate with material control & accountability and protective-force planning
- Prepare physical protection plans, security analyses, and technical submittals for DOE authorization, and support interactions with DOE (and NRC where applicable)
- Handle Safeguards Information (SGI) and Unclassified Controlled Nuclear Information (UCNI) appropriately
- Stay current with security methodologies, the evolving threat landscape, and international standards (IAEA Nuclear Security Series)

- Master's degree in engineering, physics, security systems engineering, or a related field
- 5–10 years in nuclear security, physical protection, or security engineering for nuclear or comparable critical facilities
- Experience with security assessment methodologies: DBT analysis, vulnerability assessment, target set identification, and physical protection system design
- Working knowledge of the US framework: DOE O 470.3 (Graded Security Protection), DOE O 474.2 and DOE-STD-1194 (material control & accountability / graded safeguards), and 10 CFR Part 73; plus the IAEA Nuclear Security Series (e.g. INFCIRC/225)
