Job description

About the Role

As a member of the nuclear engineering team, you will become the responsible engineer for a key component of the Antares reactor design such as reactivity controls and instrumentation, radiation shielding, fuels, materials, thermal hydraulics, safety, or licensing. 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.

Roles and Responsibilities
  • Assist with neutronics modeling and simulations using MCNP, Serpent, or SCALE
  • Support Multiphysics analyses (thermal-hydraulics, heat transfer, structural mechanics)
  • Participate in experimental validation of simulation results
  • Collaborate with senior engineers on iterative design tasks
  • Contribute to documentation and regulatory reporting
  • Participate in hardware demonstrations and prototype testing
Basic Qualifications
  • Bachelor's degree in Nuclear Engineering or related technical field
  • Familiarity with neutron transport software (MCNP, Serpent, SCALE)
Preferred Skills & Experience
  • Familiarity with Python or similar programming language
  • Coursework or internships involving Multiphysics modeling
  • Interest or experience in microreactors, heat pipe cooled reactors, or other advanced reactors
  • Exposure to fast-paced project environments
  • Proven ability to quickly learn new technical concepts
  • Strong communication skills
Pay Ranges

Nuclear Engineer I: 120k-135k

Nuclear Engineer II: 135k-165k

Your actual level and base salary will be determined on a case‑by‑case basis and may vary based on the following considerations: job‑related knowledge and skills, education, and experience.
