Lead, Nuclear Criticality Safety

The role

You will build and lead the criticality safety program for a Part 70 fuel cycle facility from the ground up. You will develop criticality safety evaluations and perform analyses using computational tools to ensure regulatory compliance.

What you will do

• Own the criticality safety program end-to-end
• Develop and maintain nuclear criticality safety evaluations (CSEs)
• Perform criticality safety analyses using computational methods and tools
• Serve as the primary technical point of contact for NRC licensing interactions
• Ensure compliance with NRC, DOE, and ANSI/ANS criticality safety standards
• Mentor and provide technical review for other criticality safety engineers
• Conduct audits, inspections, and reviews of facility operations
• Collaborate with engineering, operations, and regulatory teams
• Provide technical guidance and training to personnel
• Investigate criticality safety incidents and develop corrective actions

Required qualifications

• Evidence of exceptional ability
• 8+ years of nuclear criticality safety experience, including direct authorship of criticality safety evaluations at a DOE or NRC-licensed facility
• Bachelor's degree in Nuclear Engineering, Physics, or a related field
• Strong knowledge of criticality safety regulations, standards, and methodologies
• Proficiency in computational tools such as SCALE, MCNP, or similar software
• Ability to perform trade studies and make clear recommendations using first principles and engineering fundamentals
• Strong verbal and written communication skills
• Ability to obtain and maintain required security clearance and access authorization
• Ability to work extended hours and weekends as necessary

Nice to have
