Eos Atomics Electrical Technician/Engineer San Francisco, CA · Full time Company website

Apply for Electrical Technician/Engineer

Eos Atomics is a San Francisco-based startup building commercial fusion technology to solve humanity’s most pressing energy challenge. We are a lean, technical team built for speed, precision, and uncompromised execution.

We design, build, test, and deploy novel systems at record pace. We expect full technical ownership, high scientific rigor, and the curiosity to tackle problems others deem impossible.

We debate openly, test relentlessly, and value ideas over hierarchy. If you want to push the frontier of fusion energy, you belong at Eos Atomics.

The Role

You will own the physical build, integration, and rapid debugging of the electrical hardware powering our fusion devices and test stands. You are the team’s go-to builder—working at the bench and on the device to bring complex schematics to life.

At Eos Atomics, technicians work alongside engineers as equal partners in execution. Your diagnostic instincts, craftsman-level execution, and proactive problem-solving will directly determine our hardware iteration speed and operational uptime.

What You’ll Do

·      Bring-Up & System Debug: Execute end-to-end complex electrical systems—including high-voltage interfaces, precision sensor arrays, power distribution, analog and digital signals processing.

·      Harnessing & Panel Integration: Fabricate, modify, and route custom, high-reliability cable harnesses and control panels for harsh electro-magnetic and high-vacuum environments.

·      Hardware Diagnostics: Diagnose complex system failures using oscilloscopes, logic analyzers, multimeters, and high-voltage test equipment.

·      Design Feedback Loop: Interpret schematics, assembly drawings, and PCB layouts; collaborate directly with design engineers to drive Design-for-Manufacturability (DFM) and reliability improvements.

·      Documentation & Standards: Author clear rework notes, build procedures, and acceptance test plans. Ensure all builds comply with company, state, and federal safety standards.

·      Facility & Test Readiness: Maintain high lab standards via 5S principles, manage critical spares, and support facility power/data drops to ensure maximum test stand readiness.

Required Qualifications

• Extensive hands-on electrical technician experience in a high-rigor environment (aerospace, robotics, automotive, particle physics/national lab, or deep-tech hardware startup).
• Lab Equipment & Diagnostics: Expert proficiency with diagnostic tools including oscilloscopes, multimeters, benchtop power supplies, spectrum analyzers, and hot-air rework/soldering stations.
• Schematic & CAD Literacy: Ability to read and interpret schematics, PCB layouts, BOMs, and assembly drawings; working knowledge of PCB viewer tools (Altium, KiCad, EAGLE, or similar). Demonstrated ability to follow detailed instructions and protocols.
• Harnessing & Interconnects: Demonstrated experience building custom cable harnesses, crimping high-reliability connectors (e.g., Deutsch, Amphenol, Molex), and interpreting complex wiring diagrams.
• Firmware & Bring-Up: Experience flashing firmware and running basic board bring-up scripts using debug probes (J-Link, ST-Link, FTDI).
• Mindset & Ownership: Exceptional attention to detail, proactive problem-solving, and a track record of taking personal ownership over unblocking hardware issues in a fast-paced R&D/Startup environment.

Preferred Qualifications

• High-Voltage / Power Systems: Familiarity with pulsed and DC high-voltage (HV) systems and safety protocols, power electronics, or high-current systems.
• Noise & EMI Mitigation: Understanding of shielding, grounding, and signal integrity best practices in noisy electromagnetic environments.
• DFM / Design Input: Experience providing direct Design-for-Manufacturability (DFM) feedback to electrical design engineers.
• Working experience with machining and fabrication (lathe, mill, CNC, drill press, etc.)

What We Offer

• Competitive Compensation & Equity. Success is shared. Competitive base and meaningful equity in the form of early-stage stock options.
• Benefits: Generous paid leave policy, paid holidays, and a company-wide December break
• Experience: Small team with low barriers to action, solving complex engineering challenges, building real hardware
• Impact: Direct ownership of first-of-a-kind systems without the red tape of traditional research facilities
