Internship Nuclear Design provides hands-on training for students or recent graduates, focusing on learning design principles. Nuclear Engineers are full-time professionals responsible for designing, analyzing, and maintaining nuclear systems. Internships serve as a stepping stone to a career in nuclear engineering, which involves more responsibility and advanced tasks.

What kinds of projects or tasks can an intern expect to work on in a Nuclear Design internship?

As a Nuclear Design intern, you can expect to work on a variety of projects that support senior engineers in designing and analyzing nuclear systems. Typical tasks include assisting with computer simulations, preparing technical reports, and supporting safety assessments. Interns often collaborate with multidisciplinary teams to solve engineering challenges and may participate in meetings to discuss design modifications. This hands-on experience helps interns develop practical skills and gain insight into the workflow of nuclear engineering projects.

What are Internship Nuclear Design positions?

Internship Nuclear Design positions are entry-level roles for students or recent graduates interested in the field of nuclear engineering and design. These internships provide hands-on experience in designing nuclear systems, reactors, or components under the supervision of experienced engineers. Interns typically assist with technical analysis, computer modeling, safety reviews, and documentation related to nuclear projects. The aim is to develop practical skills and gain industry insight, often leading to future career opportunities in nuclear engineering.

What are the key skills and qualifications needed to thrive as an Internship Nuclear Design, and why are they important?

To thrive as an Internship Nuclear Design, you generally need a background in nuclear engineering or a related field, with strong analytical and problem-solving abilities. Familiarity with industry-standard simulation software (such as MCNP or SCALE), CAD tools, and a basic understanding of regulatory and safety systems is often required. Strong teamwork, attention to detail, and effective communication skills help interns contribute meaningfully and learn from experienced professionals.

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.
Culture
At Antares, we like to specifically tie each role to our founding document's set of values-here are the top five cultural values we think you should believe at your core to be successful:
  • Think in Systems - Energy and Defense are complex ecosystems with numerous stakeholders with competing priorities, conflicting policies, perverse incentives, and emergent and path-dependent properties. First principles thinking alone is insufficient. 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
  • Obsess over the End User - The customer and end user are often not the same. We will never build globally competitive commercial products if we lose sight of our end users and their entire interaction with the product life cycle
  • Be Unconstrained by Convention - Our only limits are the laws of physics. Many, even experts, will say what we are working on is impossible. They said the same about SpaceX reusing rockets. Generationally impactful companies, by definition, must accomplish the seemingly impossible. If it were easy, it would have already been done. Never shy away from a solution because it has never been tried before, and never choose to do something because that's "how it's always been done"
  • Go Where the Work Is - Never miss a chance to meet a customer, user, or stakeholder face to face, even if that means hopping on a plane. If you can't make it, find a teammate who can channel your intentions and go in your place. Deep work can be done from anywhere, but we believe teams are built in person, and aim to maximize our time together
  • Operate in the Grey - Embrace nuance in pursuit of truth. Question every fundamental assumption
