Conduct radiological consequences and control room habitability analyses using accepted regulatory methodologies
Perform reactor pressure vessel and structural component fluence evaluations to support shielding and material assessments
Benchmark analytical models against experimental data and industry guidance to ensure technical defensibility
Prepare technical reports and contribute to licensing documentation, including PSAR, FSAR, and responses to NRC Requests for Additional Information (RAIs)
Participate in technical meetings with internal teams, partners, clients, and the U.S. Nuclear Regulatory Commission
Mentor junior engineers and support the development of analysis standards and documentation best practices

Requirements:

Eligibility to work under U.S. Department of Energy 10 CFR Part 810 export control regulations
Bachelor’s degree in Nuclear Engineering, Physics, or a closely related field with 10+ years of relevant experience
- OR Master’s degree with 8+ years of relevant experience
- OR PhD with 6+ years of relevant experience
Demonstrated experience in radiation shielding design, source term development, and radiological dose assessment
Proficiency with radiation transport and dose analysis tools such as MCNP, SCALE, ADVANTG, GALE, ARCON96, RADTRAD, or equivalent codes
Working knowledge of nuclear power plant operations and radiological protection programs
Familiarity with NRC licensing processes and NUREG‑0800 Chapters 11 and 12 requirements
Strong technical writing, documentation, and communication skills
Programming or scripting experience (e.g., Python) to support analysis automation and data processing
Experience supporting NRC audits, RAIs, and technical review meetings
Experience integrating shielding design with plant layout and multidisciplinary engineering teams
