How much do remote nuclear criticality safety engineer jobs pay per year?

As of Sep 5, 2026, the average yearly pay for remote nuclear criticality safety engineer in the United States is $154,474.00, according to ZipRecruiter salary data. Most workers in this role earn between $146,000.00 and $161,000.00 per year, depending on experience, location, and employer.

What does a remote nuclear criticality safety engineer do?

A Remote Nuclear Criticality Safety Engineer is responsible for ensuring that nuclear processes and materials remain within safe limits to prevent accidental criticality incidents, which can release dangerous levels of radiation. Working remotely, they analyze facility designs, review operational procedures, and assess safety systems to ensure compliance with regulatory standards. They also provide technical guidance, perform risk assessments, and develop safety documentation to support nuclear operations. Their work is essential for maintaining the safe handling, storage, and transport of fissile materials in nuclear facilities.

What are the key skills and qualifications needed to thrive as a remote nuclear criticality safety engineer?

To thrive as a Remote Nuclear Criticality Safety Engineer, you need a strong background in nuclear engineering or physics, criticality safety analysis, and typically a relevant degree or professional certification. Familiarity with industry-standard codes (like ANSI/ANS-8 series), Monte Carlo simulation tools (such as MCNP), and regulatory compliance systems is essential. Strong analytical thinking, problem-solving skills, and clear communication are vital for collaborating remotely and ensuring regulatory adherence. These skills and qualifications are crucial for maintaining nuclear safety, preventing criticality incidents, and ensuring accurate risk assessments in remote work environments.

What are some unique challenges faced by remote nuclear criticality safety engineers, and how can they effectively collaborate with onsite teams?

Remote Nuclear Criticality Safety Engineers often face the challenge of maintaining clear and timely communication with onsite personnel, especially when assessing real-time safety concerns or reviewing facility changes. To be effective, they rely heavily on detailed documentation, virtual meetings, and remote access to site data and modeling software. Building strong relationships with onsite engineers and safety staff is essential for seamless collaboration and ensuring all safety protocols are consistently followed. Proactive communication and regular check-ins help bridge the gap created by physical distance and support thorough safety analysis and compliance.

What is the difference between Remote Nuclear Criticality Safety Engineer vs Remote Nuclear Safety Analyst?

AspectRemote Nuclear Criticality Safety EngineerRemote Nuclear Safety Analyst
CredentialsTypically requires certifications like ANSI/ANS-8, engineering degrees, and nuclear safety trainingOften requires similar certifications, safety training, and analytical skills
Work EnvironmentPrimarily in nuclear facilities, safety reviews, and compliance documentationInvolves safety assessments, regulatory reporting, and risk analysis, often remotely
Industry UsageCommonly employed in nuclear power plants, research reactors, and fuel facilitiesUsed across nuclear regulatory agencies, consulting firms, and industry operators

The main difference is that Remote Nuclear Criticality Safety Engineers focus specifically on preventing nuclear chain reactions, requiring specialized criticality safety expertise, while Remote Nuclear Safety Analysts handle broader safety assessments and regulatory compliance. Both roles require strong technical knowledge and safety certifications, but their focus areas and daily tasks differ within the nuclear industry.

  • Update, improve, and/or create software to satisfy all licensing requirements during the Validation and Verification (V&V) process
  • Incorporate additional 3rd-party programs in our simulation ecosystem as necessary to support licensing
  • Design and execute sensitivity studies to understand the effects and validity of various modeling assumptions, including meshing, physics coupling, transport options, cross section preparation, fission product models, spatial kinetics, etc., and adjust methods as necessary
  • Train and support reactor designers and developers in the use of the design software suite
  • Build and apply methods to assess the propagation of uncertainty and their effect on safety margins
  • Enhance engineering team's ability to build models and make meaningful conclusions from simulation output through input tools, visualization, reports, etc.
Requirements
  • B.S. degree in Nuclear Engineering with 5-20 years of experience
  • M.S. degree in Nuclear Engineering with 3-15 years of experience
  • Ph.D. degree in Nuclear Engineering with 2-10 years of experience
  • Fast reactor physics and design intuition
  • Experience in nuclear design/analysis methodologies including criticality, flux/power distributions, fuel management optimization, reactivity coefficients, shielding, activation, control rod worth, detector response, and uncertainty analysis
  • Knowledge of reactor physics analysis methods (deterministic and stochastic particle transport, isotopic depletion, perturbation theory, nuclear data, kinetics, etc.)
  • Experience with nuclear engineering software such as DIF3D, MC2, PARTISN, MCNP, Serpent, SCALE, PARCS, APA, CASMO, DRAGON, ARMI, etc. preferred
  • Strong computational expertise and programming skills in scientific computing languages (Python, C++, Fortran bonus)
  • Proven ability to automate simulation tools and integrate software
  • Experience with software development tools (IDEs, version control, debuggers, documentation tools)
  • Knowledge of nuclear methodology interaction with the NRC under an ASME NQA-1 compliant QA environment preferred
  • Good understanding of numerical methods and applied mathematics (PDEs, stability, statistics, analysis, dynamics)
  • Strong technical documentation skills
  • Ability to meet aggressive schedules and deliver consistently
  • Self-motivated with a passion for software best practices and teamwork
  • Excellent verbal communication skills
