About the role

  • The ideal candidate has a mix of industry and academic experience, and has worked in a team-oriented environment to mature nuclear concepts.
  • While you may have a specialty, you're not afraid to operate as a generalist in a growing organization.
  • Coordinate validation and verification activities

Responsibilities

  • Lead complex neutronics modeling and Multiphysics analysis
  • Responsible nuclear engineer for design and integration of components as assigned
  • Develop and implement modeling and simulation methods and tools
  • Lead cross-disciplinary integration efforts across neutronics, thermal-hydraulics, structural mechanics, materials, and reactor operations to ensure design margins are maintained across all Figures of Merit (FOMs) and safety-critical performance metrics
  • Identify and define validation, verification, qualification, and testing requirements across engineering disciplines, including opportunities to leverage startup, commissioning, and power ascension testing data for model development and design maturation

Requirements

  • Deep experience with and understanding of MCNP, Serpent, or SCALE
  • Experience with Multiphysics simulations and methods (thermal-hydraulics, structural, heat transfer), reactor kinetics, safety analysis, or integrated systems modeling
  • Deep understanding of reactor shielding design, radiation transport analysis, and variance reduction methodologies, including experience with ADVANTG, MAVRIC, Attila4MC, or equivalent tools
  • Experience performing integrated nuclear-thermal-mechanical analyses for reactor structures and components, including structural graphite, high-temperature steels, and other advanced reactor materials
  • Strong systems engineering mindset with the ability to work effectively across disciplinary interfaces and identify data needs for validation, verification, qualification, and licensing activities
  • Experience planning and executing experimental programs to generate qualification data, including leveraging commissioning and power ascension campaigns to supplement analytical and modeling efforts
  • Think probabilistically and then take action. "If you want to be certain, then you are apt to be obsolete." Over-optimizing the components often degrades the system
  • If you can't make it, find a teammate who can channel your intentions and go in your place.

Nice to have

  • Preferred Skills & Experience:

Skills

  • Advanced programming proficiency (Python, C++, or similar)
  • Strong leadership and mentorship skills
  • Demonstrated success in regulatory processes (DOE, NRC, DoD)
  • Previous experience at dynamic tech companies or startups
  • Experience with advanced reactor transient and systems analysis tools such as SAM, AGREE, PARCS, or equivalent nuclear systems codes
  • Experience with reactor commissioning, startup testing, power ascension testing, and operational readiness activities for nuclear systems
