Antares
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 tie each role to our founding document’s set of values. Our top five cultural values are:
Think in Systems – energy and defense are complex ecosystems; first principles thinking alone is insufficient. Think probabilistically and then take action.
Obsess over the End User – the customer and end user are often not the same.
Be Unconstrained by Convention – our only limits are the laws of physics.
Go Where the Work Is – meet customers, users, or stakeholders face to face when possible.
Operate in the Grey – embrace nuance in pursuit of truth; question every fundamental assumption.

Employment decisions are based solely on merit, competence, and qualifications, without regard to race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, mental or physical disability, or any other legally protected status.
