Excellent problem-solving, communication, and teamwork skills help you effectively collaborate with multidisciplinary teams and convey complex technical information. These skills are essential for ensuring the safety and regulatory compliance of nuclear facilities, protecting public health, and supporting efficient plant operations.

What are some typical challenges nuclear safety analysis engineers face in their daily work?

Nuclear Safety Analysis Engineers often face the challenge of interpreting and applying complex regulations while conducting thorough safety assessments and evaluations for nuclear systems. Balancing stringent safety requirements with operational efficiency requires a keen attention to detail and the ability to perform in-depth risk analyses under tight deadlines. Collaborating with operations, regulatory, and engineering teams is vital, as new issues and unexpected scenarios may arise that require rapid problem-solving. Successfully managing these challenges ensures both regulatory compliance and the protection of people and the environment.

What is a nuclear safety analysis engineer?

A Nuclear Safety Analysis Engineer assesses and ensures the safety of nuclear facilities by analyzing potential risks, accidents, and system performance. They use computational models and simulations to evaluate reactor behavior under different conditions. Their work ensures compliance with regulatory standards and helps improve operational safety. They collaborate with engineers, regulators, and operators to develop safety guidelines and emergency protocols.

Job description

Deep Fission is a nuclear technology company pioneering the development of a revolutionary deep borehole pressurized water reactor. We recently completed a private placement financing and Alternative Public Offering and are now operating as a public company while maintaining our startup agility and innovation focus. With strategic partnerships in place, strong private and public investment, and active engagement with the U.S. Nuclear Regulatory Commission (NRC), we are executing our next phase of growth as we advance our groundbreaking nuclear technology toward commercial deployment.
Deep Fission is seeking a mid-career Nuclear Safety Analysis Engineer to support the design, development, and safety analysis of our Gravity Nuclear Reactor. Functions within this role include performing accident analyses and safety calculations that support the reactor's safety case across a first-of-a-kind subsurface deployment.
The ideal candidate brings hands-on experience in accident analysis, radiological consequence evaluation, and safety analysis report development within a regulated nuclear environment, and can translate that technical foundation into defensible inputs for licensing submittals and regulatory engagement with the NRC and DOE. This role reports into the Nuclear Safety Analysis organization and works closely with licensing, reactor design, and health physics teams as the company advances toward pilot deployment and commercial licensing.
Key Responsibilities
  • Accident & Safety Analysis
    • Perform and document accident analyses, including design basis accident (DBA) and beyond-design-basis event evaluations, to support the reactor's safety case.
    • Develop and apply nuclear safety analysis methods and codes to evaluate reactivity control, core response, and system behavior under off-normal conditions.
    • Evaluate radiological consequences of accident scenarios in coordination with health physics, incorporating dose assessment inputs into safety documentation.
    • Contribute to probabilistic and deterministic safety analyses supporting design decisions and regulatory submittals.
  • Safety Basis & Licensing Documentation
    • Support development of safety analysis reports (SAR/PSAR), technical specifications, and licensing basis documentation.
    • Support preparation of licensing submittals and responses to NRC and DOE requests for additional information related to safety analysis.
    • Interpret regulatory requirements (e.g., 10 CFR Part 50/52) and translate them into safety analysis inputs and design recommendations.
    • Maintain traceability between safety analysis assumptions, design inputs, and licensing commitments.
  • Technical Collaboration
    • Coordinate with reactor design, health physics, and licensing teams to ensure safety analysis assumptions remain consistent with evolving design.
    • Coordinate with external consultants and national laboratory partners on safety analysis methodology and validation work.
    • Promote a proactive nuclear safety culture across engineering, licensing, and field-based activities.

Required Skills & Experience
  • 7-10 years of relevant experience in nuclear safety analysis or accident analysis within a regulated nuclear environment (commercial nuclear, DOE, national laboratory, or naval nuclear); commercial nuclear background preferred.
  • Demonstrated, hands-on experience performing accident analysis, including design basis accident evaluation.
  • Experience with nuclear safety analysis codes and methods (e.g., MELCOR, RADTRAD, SCALE, ORIGEN, or comparable tools).
  • Bachelor's degree in Nuclear Engineering or a related technical field, with a solid understanding of reactor physics and safety analysis principles.
  • Working knowledge of radiological consequence assessment as it relates to accident analysis (close coordination with health physics expected; CHP credential not required for this role).
  • Strong technical writing skills, with the ability to produce clear, defensible documentation suitable for regulatory review.
  • Must be a U.S. person eligible to meet DOE Export Control requirements under 10 CFR 810.
  • Ability to work independently in a remote-first, cross-functional environment with senior stakeholders.
  • Willingness to travel domestically for team offsites, training sessions, and site visits as required. Approximately 20% travel.

Desired Skills & Experience
  • Direct experience at a commercial nuclear power plant, in a Reactor/Nuclear Safety Analysis or Licensing group.
  • Advanced degree (MS) in Nuclear Engineering or a related field.
  • Direct experience with SMRs, Gen IV technologies, or first-of-a-kind nuclear reactor development.
  • Demonstrated experience navigating NRC or DOE licensing processes, including SAR development and RAI responses.
  • Familiarity with nuclear QA programs (e.g., NQA-1) and compliance documentation.
  • Experience with probabilistic risk assessment (PRA) tools and methods (e.g., SAPHIRE).
  • Proficiency with engineering software tools and AI-enabled platforms.
  • Experience in startup or innovation-driven organizations where scope and process are actively evolving.

Key Competencies
  • Safety Analysis Rigor - Performs sound, well-documented accident and safety analyses that hold up under NRC and DOE review.
  • Technical Depth - Applies reactor physics and systems knowledge to identify and evaluate credible accident scenarios.
  • Adaptability & Problem-Solving - Comfortable operating in first-of-a-kind environments where precedent is limited and methods are actively being established.
  • Stakeholder Influence - Builds trust and alignment across engineering, licensing, health physics, and regulatory stakeholders.
  • Decision-Making - Balances technical rigor with practical judgment to support design and licensing decisions on schedule.
