Antares, Los Angeles
As a Space Mechanical Design Intern, you will contribute to the mechanical design and development of Antares reactor and power systems, with a particular focus on space applications. You will work on hardware ranging from space radiators and power conversion components to reactor mechanical systems, taking projects from early design and manufacturing concepts through integration and testing.
You will also evaluate how Antares systems could be deployed across different applications, translating customer operating conditions into technical requirements and concepts of operation. This role offers exposure to both detailed hardware development and the system-level engineering required to deploy nuclear power systems in space and terrestrial applications.
To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.

Internships at Antares are anything but ordinary. You'll work alongside our team as we design, build, and test fission microreactors built to deliver reliable energy for critical missions on Earth, in space, and underwater.
Our interns contribute to real work from day one. Depending on your role, you may touch hardware, write and test software, support manufacturing and operations, or help build the systems that allow Antares to move quickly as we scale. You'll work alongside engineers, operators, and other experts solving challenging problems—and you'll leave your internship with hands-on experience that's difficult to find anywhere else.
We work hard, move quickly, and take pride in what we're building. If you're excited to learn by doing and want to contribute to the next generation of nuclear energy, we'd love to have you join us next summer.
We will be running two separate cohorts to accommodate students on both semester and quarter schedules:
Cohort #1
Cohort #2
All internship roles are based at our Torrance headquarters and require interns to work onsite five days per week. We will not be considering candidates for remote or hybrid arrangements.
Interns will receive a relocation and housing stipend as part of their offer package.
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:
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.
The Antares team hails from SpaceX, the White House, the Pentagon, the Department of Energy, MIT, Rigetti Computing, General Atomics, Relativity Space, Ursa Major, and National Laboratories like Idaho, Oak Ridge, Los Alamos, and Savannah River. Antares has raised over $600M in venture capital from top-tier investors and has hundreds of million-dollars on contract with the military services, NASA, and the Department of Energy.
