Antares
About Antares
At Antares, our long-term mission is to make clean energy abundant from Earth to the Asteroid Belt. We’re building mass-producible, inherently safe, deployable microreactors that can be used terrestrially, underwater, and in space. Formed in 2023, Antares has a team from SpaceX, The White House, MIT, Rigetti Computing, The Air Force, General Atomics, Relativity Space, Ursa Major, Ultra Safe Nuclear, and Los Alamos National Laboratory. Antares has raised over $39M in venture capital and over $4M in government funding. About the Team:
The Electrical Engineering team designs, builds, tests, installs, and operates hardware that monitors and controls the reactor, maintains safe operating conditions, and can shut down the reactor if needed. The team also converts core heat into usable electricity and collaborates with other teams to monitor critical parameters for each project. With a First-of-a-Kind (FOAK) reactor design underway, you will help establish testing capabilities for our custom electronics. Role
Senior Electrical R&D Specialist
— to establish and lead a multidisciplinary electrical lab supporting Engineering Development Units (EDUs), demo rigs, prototypes, and integrated test articles. In this role, you will design and build panels and racks, fabricate harnesses and cable assemblies, and develop safe AC, DC, and high-voltage test benches. You will also integrate sensors and DAQ systems, perform hands-on soldering and harnessing, standardize panel and rack designs, implement interlocks and lockout/tagout procedures, and ensure professional lab operations through calibration, ESD control, inventory management, documentation, and clear work instructions. Responsibilities
Install industrial controls hardware in compliance with NFPA 70 (NEC) and NFPA 79 standards. Wire and modify electrical control panels in accordance with UL 508A standards, ensuring layouts meet safety and serviceability requirements. Author LOTO procedures, arc‑flash labels, and PPE selection for energized work, aligned with NFPA 70E. Troubleshoot faulty instrumentation, harnesses, and general electrical systems to restore safe and reliable operation. Maintain the electrical shop, including tools, consumables, calibration of equipment, and the controls hardware inventory. Build, solder, crimp, and verify harnesses and cable assemblies to IPC/WHMA‑A‑620 and IPC‑A‑610 workmanship standards; oversee box builds and PCB integration. Design and operate modular AC/DC benches with protection, interlocks, and measurement capability; safely support high‑voltage bring‑up per NFPA 70E practices. Plan, construct, and operate EDUs, demonstration rigs, and prototype test articles, including bring‑up procedures and integrated instrumentation for data capture. Program and configure industrial controls hardware such as VFDs, motor starters, PLCs, and electronic circuit breakers. Review and redline drawings and technical documentation, and provide design feedback to the engineering team. Use EPLAN to generate reports, bills of material, wire lists, and manufacturing data; manage schematic documentation. Define and enforce panel/rack and harnessing standards (wire color codes, labeling, test points) to drive repeatability and serviceability. Create, maintain, and update assigned tasks for documenting and reporting work in progress and completed activities. Collaborate with mechanical, firmware, and systems engineers to define interfaces, requirements, and integration plans for multidisciplinary test articles. Ensure compliance with EMI/EMC, safety, environmental, and industry‑specific requirements in all test infrastructure and operations. Mentor junior engineers and technicians, and lead small build/test teams to deliver milestones. Prepare compliance doc sets for UL 508A panels and NEC wiring (schematics, BoMs, wire lists, torque/spec sheets). Basic Qualifications
High school diploma or GED 5+ years of work in a relevant field (manufacturing/test/R&D) 4+ years working on electrical control systems Hands‑on panel/rack wiring and harness fabrication (crimping/soldering, continuity/hipot testing) Experience with AC (single/three‑phase), DC, and safe HV bring‑up in a lab/test environment Preferred Skills & Experience
Experience with electrical troubleshooting Experience with schematic comprehension Demonstrated prior experience working with complex systems including cryogenic propellants, high pressure gas systems, hydraulics and/or combustion devices Demonstrated working knowledge of components (valves, regulators, sensors, power supplies) and hands‑on skills (tube fabrication, metalworking, wiring) Demonstrated hardware testing experience with rocket engines, or spacecraft Experience in a startup or agile development environment UL 508A industrial control panel design/build; NEC/NFPA 79 familiarity EPLAN or similar ECAD (e.g., AutoCAD Electrical); ability to generate BoMs/wire lists PLC/VFD (Allen‑Bradley/Siemens), DAQ (NI cDAQ/cRIO or similar), instrumentation & signal conditioning EMI/EMC test awareness and grounding/shielding best practices Ability to create work instructions, calibration plans, and lab safety SOPs (LOTO/ESD) Additional Requirements
Ability to work long hours and weekends as necessary to support critical milestones Location
Torrance, CA — in a 145,000 square foot, brand new facility with open spaces for team collaboration, R&D, and production, and access to major freeways. The facility is located in Los Angeles\' vibrant tech ecosystem alongside many high growth startups and enterprises. Culture
