Welding Engineer
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 Team
As a Welding Engineer II at Antares, you will support the development, qualification, and production of welded hardware for our reactor systems. You will own welding processes from early design and material selection through procedure development, qualification, manufacturing, inspection, and final acceptance. This role requires a strong understanding of welding metallurgy, fabrication processes, and weld quality—particularly for stainless steels, nickel-based superalloys, and other materials used in high-temperature and demanding environments. You will work closely with design, materials, manufacturing, quality, and external suppliers to ensure welded assemblies meet performance, reliability, and regulatory requirements.
The ideal candidate combines sound welding fundamentals with a hands-on, practical approach to manufacturing. You should be comfortable working directly with welders and technicians, troubleshooting issues on the floor, and developing scalable processes for first-of-a-kind reactor hardware.
