This is a full-time, onsite role based at our headquarters in Denver, CO.

As an Electrical Engineer - Signal Distribution & Controls, you will apply your skills to own and deliver end-to-end electrical system implementation, including low voltage power distribution and protection, control panels and cabinets, harnessing, and electrical process and interface diagrams (P&IDs). We are looking for engineers who bring strong technical depth, systems thinking, and a commitment to quality to help build the electrical foundation of next-generation fusion systems

Responsibilities

• Own electrical architecture and implementation for assigned subsystems, translating system and control requirements into safe, compliant electrical designs.
• Design and own signal distribution and protection schemes, including grounding, shielding, fault protection, and electrical safety considerations.
• Lead the design of control panels, cabinets, and electrical packaging, with a focus on robustness, serviceability, and scalability.
• Own cable and harness architecture, including interface definition, routing strategy, and documentation.
• Develop and maintain electrical-focused P&IDs and interface diagrams describing power, signal, interlock, and utility interfaces.
• Use P&IDs as a cross-disciplinary communication tool between Electrical, Controls, Mechanical, Safety, and Operations.
• Ensure consistency between P&IDs, schematics, wiring diagrams, harness drawings, and control I/O definitions.
• Produce complete, build-ready electrical design packages, including P&IDs, schematics, wiring diagrams, harness drawings, ICDs, BOMs, and supporting documentation.
• Support design reviews, hazard analyses, safety reviews, system integration, commissioning, and bring-up activities.
• Lead electrical failure analysis and root-cause investigations, driving corrective actions and continuous improvement.
• Design electrical systems, panels, harnesses, and documentation in accordance with applicable internal and industry standards, including IPC/WHMA-A-620, IPC-A-610, IPC-J-STD-001, UL 508A, NFPA 70/79, and ANSI/ISA-5.1 for P&IDs.

Qualifications

• Education: Bachelor’s degree in Electrical Engineering or equivalent.
• Experience: 3+ Years of Experience in Electrical Engineering.
• Demonstrated experience owning electrical system design for complex hardware systems.
• Strong background in power distribution, protection, grounding, and electrical safety.
• Experience designing control panels, cabinets, and electrical packaging.
• Experience creating and maintaining electrical P&IDs, process diagrams, or electrical interface diagrams for complex systems.
• Familiarity with common offerings from large electrical distributors like Rockwell Automation, Siemens, and/or Beckhoff.
• Ability to produce clear, build-ready electrical documentation.
• Familiarity with industry standards applicable to electrical systems, including cable and wire harness standards (IPC/WHMA-A-620), electrical panel standards (UL 508A, NFPA 70/79), and P&ID standards (ANSI/ISA-5.1).
• Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Desired

• 5+ Years of Experience using P&IDs in safety reviews, commissioning, or operational documentation.
• Hands-on experience with harness and cable design.
• Experience supporting system integration, commissioning, and failure analysis.
• Background working closely with controls, mechanical, and systems engineering teams.
