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

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.

Roles and Responsibilities:

• Develop and maintain comprehensive Job Hazard Assessments (JHAs) for all manufacturing and test operations

• Build and implement safety protocols and procedures for manufacturing, testing, and reactor assembly/operation

• Create and deliver safety training programs, including alkali-metal handling, thermal testing, welding, and electrical safety

• Develop into the company’s Radiation Safety Officer, establishing radiological safety programs, monitoring, and controls

• Maintain the hazardous materials inventory and ensure compliant storage, labeling, and handling

• Manage hazardous waste disposal, including characterization, packaging, manifests, and vendor coordination

• Lead PPE assessments, selection, training, inspection, and lifecycle management

• Conduct EHS audits, inspections, and incident investigations, driving root-cause analysis and corrective actions

• Primary liaison for Antares with city, state, and federal authorities responsible for EHS

Basic Qualifications:

• Bachelor’s degree in Environmental Health & Safety, Engineering, Chemistry, or other STEM field

• 3+ years of EHS experience in industrial manufacturing, high-hazard test environments, nuclear, aerospace, or chemical sectors

• Proven ability to develop JHAs, safety procedures, and multi-hazard training programs.

• Experience with hazardous-materials control, hazardous-waste management, and PPE program development

Preferred Skills & Experience:

• Professional certifications such as CSP, CIH, CHMM, or RSO training/experience

• Experience with radiological work, radiological safety programs, or RSO responsibilities

• Familiarity with alkali-metals, high-temperature testing, or rigging and handling

• Strong communication and training delivery skills across technical and nontechnical teams

• Ability to operate in a dynamic startup environment with high ownership and hands-on execution

Additional Requirements:

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

Location

• The Antares HQ is located in Torrance, CA in a 145,000 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 HQ is in the heart of Los Angeles' vibrant emerging tech ecosystem alongside many other high growth startups and enterprises.

Culture

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
