Job description

About Us

At Antares, our long-term mission is to make clean energy abundant from Earth to the Asteroid Belt. We’re fueled by the belief that advanced nuclear energy can strengthen our military, solve the climate crisis, elevate global living standards, and expand humanity's presence in outer space. To achieve our mission, we’re building mass-producible, inherently safe, deployable microreactors that can be used terrestrially, underwater, and in space.

Formed in 2023, the Antares team hails from SpaceX, The White House, MIT, Rigetti Computing, The Air Force, General Atomics, Relativity Space, Ursa Major, and National Laboratories like Los Alamos, Idaho, and Oak Ridge. Antares has raised over $130M in venture capital from top-tier investors and has over $13M in government funding.

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.

Equal Opportunity

Antares is an Equal Opportunity Employer.
