Nuclear Security Engineer (Physical Protection)

Blykalla is a Swedish developer of advanced nuclear power commercializing its lead-cooled small modular reactor, SEALER, for the US and European markets. The Nuclear Security Engineer will lead physical protection design, Design Basis Threat assessment, security analysis, and authorization support for the reactor's deployment in the United States.

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)

Requirements:

• U.S. citizenship — required for eligibility for a DOE access authorization (see note below)
• Ability to obtain and maintain a DOE L access authorization (Q preferred), and to be granted access to Safeguards Information and UCNI
• 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)
• Strong analytical, problem-solving, and technical-writing skills
• Fluency in English, written and spoken
• United States. The site location will be announced as the program develops. Occasional travel to Stockholm, Sweden and to the site
• An active DOE L or Q access authorization
• ASIS Physical Security Professional (PSP) or comparable credential; involvement in bodies such as INMM
• Experience with HALEU categorization or advanced/non-light-water reactors
• Experience integrating cyber and operational-technology (OT) security with physical protection
• Working knowledge of Swedish and the Swedish framework (SSM, säkerhetsskyddslagen), given our Stockholm headquarters
