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 Role
The Government Affairs Manager is in charge of helping Antares leadership execute our DC-based strategy for engaging federal stakeholders from Congress, the Pentagon, NASA, the Department of Energy, and the Department of Homeland Security. The government affairs manager will closely monitor all events in Washington, DC, and recommend how the CEO and the Head of Federal Strategy and Policy should engage to allow Antares to capture federal business opportunities, enact legislation that removes obstacles to the development of the advanced nuclear energy industry, and enhance Antares’ reputation within the Beltway.
