Staff Space Electrical Engineer

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.

• Own the electrical system level architecture of our testbed and space nuclear reactors.
• Design and assess electronics and control systems for harsh environments (e.g., space, nuclear).
• Lead integration, bring-up, and troubleshooting across hardware, firmware, and test infrastructure.
• Produce and review controlled technical documentation (schematics/wiring, safety inputs, hazard/FMEA-style analyses, test procedures/reports).
• Evaluate multi-OS or embedded control environments for real-time signal acquisition, ensuring minimal downtime or interference.
• Coordinate with regulators regarding design basis for instrumentation loops, including fail-safe architecture or redundancy.
• Own the relevant Documented Safety Analysis (DSA) inputs that address electrical system hazards or potential single-point failures.
• Participate in each formal design review cycle, ensuring electrical/I&C sections are complete, accurate, and documented.
• Support the hazard analysis process, identifying possible electrical or instrumentation failure modes and how they're mitigated.
• Verify that the final design meets or exceeds relevant standards for safety-class or safety-significant equipment.

• Bachelor's degree in Electrical Engineering, Control Systems Engineering, or a related field.
• 8+ years in designing and analyzing electrical and/or instrumentation systems, ideally in nuclear, aerospace, energy, or industrial automation.
• Familiarity with electrical requirements for regulated environments, including wiring codes, control logic documentation, and safety classification.

• Experience with power electronics and/or power conversion systems
• Master's degree or higher in Electrical/Controls Engineering.
• Experience designing and employing electrical systems in space and/or nuclear radiation environments.
• Understanding of electronic component/system testing for space environments (vacuum, radiation, etc.), and relevant MIL and NASA/ESA standards.
• Prior experience in nuclear or defense sectors with knowledge of relevant I&C codes (IEEE 379, IEEE 497, etc.).
• Working knowledge of GDE-987 design review steps and DOE-1189 hazards classification.
• Experience with advanced control system architecture or SCADA in high-reliability contexts (aviation, nuclear, or automotive safety).
• Strong communication skills to explain complex control loops and design rationales to both engineers and regulators.

• Flexibility to support hardware development milestones—including occasional weekend or long-hour pushes.
• Willingness to travel for test campaigns or supplier engagement, as needed.

• 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:

• Think in Systems
  - Energy and Defense are complex ecosystems with numerous stakeholders with competing priorities, conflicting policies, perverse incentives, and…
