About Commonwealth Fusion Systems:

Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.

Combining decades of research, top talent, and new technologies, we’re designing and building commercially viable fusion power plants. And we're working with policymakers, suppliers, and many others to build the energy industry of the future.

We’re in the best position to make it happen. Since 2018, we’ve raised $4 billion of capital, making us the largest and leading fusion company in the world.

Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team.

If that’s you and this role fits, we want to hear from you.

Join the power movement as a Staff Electrical Engineer

We are looking for a Staff Electrical Engineer to serve as the lead electrical hardware authority for our next-generation R&D and processing equipment. In this role, you will own the end-to-end electrical design of complex machinery—focusing heavily on 480

VAC power distribution, electrical safety, signal integrity, sensor instrumentation, and control panel architecture.

You will bridge the gap between high-power electrical infrastructure and machine-level controls. While your primary mastery lies in electrical design, schematic capture, component selection, and shop-floor commissioning, your working knowledge of PLCs, field buses, and industrial automation will allow you to seamlessly bring first-of-a-kind hardware to life alongside our software and mechanical teams.

• Lead Electrical System Architecture: Architect complete power and electrical hardware platforms for complex R&D tools, managing power distribution, low-voltage DC systems, cable harness design, and power conditioning. Implement (ANSI/RIA
  15.06/OSHA compliant) control reliable safety systems for safeguarding industrial equipment
• Schematic Design & Drafting: Create, modify, and approve comprehensive electrical schematic packages (one-lines, multi-line, I/O diagrams, panel layouts, cable schedules) in AutoCAD Electrical per NFPA 79, NEC, and UL 508A standards
• Instrumentation & Sensor Integration: Sizing, specify, and integrate power supplies, circuit protection, VFDs, servo drives, safety relays, and precision sensors (thermocouples, pressure transducers, vacuum gauges, flow meters)
• Signal Integrity & EMI/EMC Mitigation: Design robust grounding, shielding, and isolation schemes to protect sensitive analog/digital measurement signals in high-power, electrically noisy, and high-magnetic field environments
• Hardwired & Control Safety Systems: Implement ANSI/RIA 15.06 and OSHA-compliant electrical safety circuits, interlocks, light curtains, and emergency stop systems to protect personnel and high-hazard industrial hardware
• Hardware Commissioning & I/O Checkout: Lead hands-on electrical testing, ring-out, power-up, and I/O validation on the tool floor using multimeters, oscilloscopes, and basic PLC diagnostics
• Controls & Software Support: Assist controls engineers in configuring EtherCAT/industrial field buses, verifying drive parameters, and debugging basic PLC code (Structured Text/TwinCAT) or HMI screens during tool bring-up
• Vendor & Panel Shop Direction: Manage external panel build shops and electrical contractors; specify panel construction details, manage component BOMs, and lead Factory Acceptance Testing (FAT)

• Education: Bachelor’s degree in Electrical Engineering (BSEE) or Mechatronics Engineering required (Master’s preferred)
• Experience: 10+ years of dedicated electrical engineering experience designing power distribution, electrical cabinets, and hardware architectures for complex industrial or R&D…
