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.
As an early member of the Antares supply chain team, you will define and execute the strategic roadmap required for the company to successfully iterate through prototyping and into full-rate production. This will include identifying, qualifying, and developing suppliers across many commodities, proactively maturing fragile or nonexistent supply chains, interfacing with engineering teams to ensure design for manufacturability, and creating the processes and systems necessary to scale our business. As a growing company, you will also have the opportunity to wear many hats and influence areas outside of supply chain.
The ideal candidate will be able to execute in an ambiguous environment, with the ability to efficiently balance many different priorities - you will be part of a small team tackling significant and complex challenges, and will have a key role in contributing to the success of the company both in the short and long-term.
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:

Energy abundance unlocks progress. It powers missions, grows economies, strengthens national security, and expands what’s possible on Earth and beyond. But in the places where power is most critical, it’s often the hardest to deliver. That’s the problem we’re solving.
At Antares, we’re building compact nuclear microreactors to deliver reliable, mobile energy where it’s needed most: remote military bases, austere industrial sites, and, one day, deep space and underwater missions. The U.S. nuclear industry hasn’t seen true momentum in decades. We’re moving it forward with urgency, humility, and a commitment to building what’s needed now.
Our team includes engineers and operators from SpaceX, Relativity Space, Ursa Major, the White House, MIT, Rigetti Computing, and the U.S. Air Force. Backed by over $130M from top-tier investors, we’re focused on shipping hardware not hypotheticals.
