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.
The Operations team supports the day-to-day workplace experience and helps employees, visitors, candidates, vendors, and guests move through the office smoothly and professionally. This role owns the front desk and provides practical support across reception, meetings, supplies, shipping, and general office needs.
We are looking for a friendly, organized, and dependable Receptionist to be the first point of contact for employees, visitors, candidates, and guests at our office. This person will create a welcoming and professional experience for everyone who walks through our doors and help keep the office running smoothly day to day.
The ideal person is proactive, attentive, and comfortable interacting with a wide range of people. You notice the little things, take initiative, and are equally comfortable welcoming an important guest, enforcing a visitor policy, or jumping into an office task that needs to get done.
We are located in Torrance, CA in a 322,000 square foot, brand new facility featuring large open spaces for team collaboration, R&D, and production, as well as easy access to the 405, 105, and 110 freeways. Our facility is in the heart of Los Angeles' vibrant emerging tech ecosystem alongside many other high-growth startups and enterprises.
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.
