Staff Space Electrical Systems Engineer

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. The Antares team hails from SpaceX, the White House, the Pentagon, the Department of Energy, MIT, Rigetti Computing, General Atomics, Relativity Space, Ursa Major, and National Laboratories like Idaho, Oak Ridge, Los Alamos, and Savannah River. Antares has raised over $600M in venture capital from top-tier investors and has hundreds of million-dollars on contract with the military services, NASA, and the Department of Energy. About the Role As the Staff Space Electrical Systems Engineer at Antares, you will analyze and guide the architecture of power distribution, instrumentation and controls, and hardware-based control systems for our terrestrial and space nuclear reactors/testbeds. You will take ownership of ongoing system-level electrical architecture, R&D testing, and integration efforts, building on existing designs, prototypes, and infrastructure. You will also work together with our Licensing team on hardware regulatory strategy to ensure our multi-platform control systems and electrical networks meet compliance milestones under DOE and NRC and other regulatory specific specifications. Roles and Responsibilities: - 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. Basic Qualifications: - 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. Preferred Skills & Experience: - 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…
