Health & Safety; EHS Lead

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 Space

X, 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.

We are seeking an EHS Lead to build and own all environmental, health, and safety programs across our advanced nuclear reactor manufacturing and testing operations. This role spans high-hazard environments including alkali-metal handling, high-temperature testing, welding, machining, electronics manufacturing, and electrical test. You will support our manufacturing operations located in Torrance, CA as well as involvement with environmental and safety needs at our initial reactor test sites.

You will develop scalable safety procedures, training, and compliance systems and ensure readiness for future deployments and eventual decommissioning activities.

Our HQ is in the heart of Los Angeles' vibrant emerging tech ecosystem alongside many other high growth startups and enterprises.

• Think in Systems - Energy and Defense are complex ecosystems with numerous stakeholders with competing priorities, conflicting policies, perverse incentives, and emergent and path-dependent properties. First principles thinking alone is insufficient. Think probabilistically and then take action. “If you want to be certain, then you are apt to be obsolete.” Over‑optimizing the…
