Summer 2026 Engineering Internship

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, Ultra Safe Nuclear, and Los Alamos National Laboratory. Antares has raised over $39M in venture capital from top-tier investors and has over $4M in government funding.

Internships Available

The Summer 2026 class has slots available for the following roles :

• Mechanical R&D / Test Engineering
• Manufacturing Engineering
• Mechanical Design Engineering
• Electrical Engineering
• Software Engineering
• Nuclear Engineering / Physics

Interns will be tasked with small starter projects, and then quickly tasked with a long-duration project that will culminate in a technical deliverable and presentation. You will be integrated and evaluated as if you are a first-year junior engineer, not just an "intern". The bar for success here is high, and the expectation is that you're able to smartly use your mentor and the resources around you to execute on your project and identify more issues and opportunities for improvement.
