General Application for Engineers

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.

We are continuing to hire talented engineers at Antares for everything from design and analysis, testing, mission management, software development, quality assurance, and operations. If you don’t see an open role that fits your experience but are passionate about creating the future of clean, abundant energy, apply to this general application! Please include a cover letter highlighting your experience, skill sets, and your areas of interest at Antares.

• Bachelors, Masters, or PhD in an engineering discipline or physics.

• Strong interpersonal and collaborative skills, enthusiasm for problem-solving, and desire to optimize modern nuclear design and operation.

• Strong project management skills and effective communication of technical concepts across multi-disciplinary teams.

• Experience in the defense, aerospace, or nuclear industry with a proven track record of high impact / ROI contributions.

• Leadership experience on a project or research team.

• Based in or ability to relocate to Los Angeles to work in person at our Torrance office

• Ability to work long hours and weekends as necessary to support critical milestones

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:

• 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 components often degrades the system

• Obsess over the End User - The customer and end user are often not the same. We will never build globally competitive commercial products if we lose sight of our end users and their entire interaction with the product life cycle

• Be Unconstrained by Convention - Our only limits are the laws of physics. Many, even experts, will say what we are working on is impossible. They said the same about SpaceX reusing rockets. Generationally impactful companies, by definition, must accomplish the seemingly impossible. If it were easy, it would have already been done. Never shy away from a solution because it has never been tried before, and never choose to do something because that's “how it's always been done”

• Go Where the Work Is - Never miss a chance to meet a customer, user, or stakeholder face to face, even if that means hopping on a plane. If you can’t make it, find a teammate who can channel your intentions and go in your place. Deep work can be done from anywhere, but we believe teams are built in person, and aim to maximize our time together

• Operate in the Grey - Embrace nuance in pursuit of truth. Question every fundamental assumption
