Los Angeles, US · Full-time · $180,000 – $250,000

About this role

At Antares, our long-term mission is to make clean energy abundant from Earth to the Asteroid Belt. We’re fueled by advanced nuclear energy to strengthen military, solve climate crisis, and expand humanity in space. We’re building mass-producible, inherently safe, deployable microreactors for terrestrial, underwater, and space use.

As Antares’ expert on turbomachinery, you will take ownership of the entire closed Brayton power conversion system. Perform detailed mechanical design, rotordynamic/structural analysis, and testing. Ensure multiple year system reliability and manufacturability.

The R&D 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 and over $4M in government funding. Formed in 2023, the team drives innovative nuclear solutions.

You will design, analyze, build, and test turbopumps for Antares reactors. Collaborate with test, controls, and quality engineers while owning critical components. Lead issue resolution, root cause investigations, and design improvements for performance and cost reduction.
