Job description

Nuclear Safety / Integrated Safety Analysis (ISA) Engineer Opportunity - Oak Ridge, TN

I'm looking for an experienced Nuclear Safety / ISA Engineer to play a key role in establishing and maintaining the safety basis for a new complex nuclear facility.

The position offers significant technical ownership, collaboration with multidisciplinary engineering teams, and involvement in a large-scale project through design, licensing, and eventual operational readiness.

Key Responsibilities

• Develop, maintain, and review facility safety documentation, including Integrated Safety Analyses (ISA), Documented Safety Analyses (DSA), and supporting technical assessments.
• Conduct hazard identification, accident analyses, and risk evaluations using methodologies such as HAZOP, FMEA, and What-If analysis.
• Identify and evaluate safety-significant systems, controls, and Items Relied On For Safety (IROFS).
• Assess engineering designs, modifications, and operating procedures for their impact on nuclear safety and regulatory compliance.
• Collaborate with process, mechanical, electrical, controls, and fire protection engineering teams to integrate safety requirements into facility design.
• Support licensing activities, regulatory reviews, technical evaluations, and operational readiness assessments.
• Provide technical guidance on nuclear criticality safety, process hazards, accident prevention, and safety-basis development.

Qualifications

• Bachelor's degree in Nuclear, Mechanical, Chemical, Safety Engineering, Physics, or a related technical discipline.
• 4+ years of experience in nuclear safety engineering, safety analysis, or safety-basis development.
• Experience developing or maintaining ISA, DSA, or equivalent nuclear safety documentation.
• Familiarity with regulatory frameworks such as 10 CFR 70, 10 CFR 830, or equivalent nuclear safety requirements.
• Strong background in hazard analysis, accident scenario evaluation, and engineered safety controls.
• Experience working in DOE nuclear facilities, commercial nuclear power, fuel-cycle operations, or similarly regulated environments.
• Eligibility to obtain and maintain a DOE security clearance.

Preferred Experience

• Experience with nuclear fuel-cycle facilities or other complex nuclear process operations.
• Familiarity with NRC licensing, regulatory inspections, or facility commissioning.
• Knowledge of nuclear criticality safety, chemical process safety, and fire protection requirements.
