Helion is a fusion power company on a mission to build the world's first fusion power plant, enabling unlimited clean electricity. Founded in 2013 and headquartered in Everett, WA, the company has raised $1.5 billion from leading investors including Sam Altman, Mithril, Capricorn Investment Group, Thrive Capital, LightSpeed Venture Capital, and SoftBank. Helion's prototype, Polaris, has achieved record-breaking plasma temperatures of 150 million degrees Celsius (13 keV), and the company is advancing toward its next-generation fusion machine, Orion.
As an Electrical Systems Engineer, you will define and develop the electrical hardware that powers and controls Helion's next-generation fusion machines. Working at the architecture level, you will ensure electrical subsystems—including power distribution, controls interfaces, sensors, and communication networks—function together as a coherent and reliable platform.
Key responsibilities include:
- Contributing to the architecture and design of electrical subsystems, ensuring alignment with overall machine requirements and operational goals
- Defining, maintaining, and managing system and subsystem requirements with clear traceability from top-level objectives to implemented hardware
- Developing and maintaining Interface Control Documents (ICDs) that define electrical, controls, and mechanical interfaces between subsystems and suppliers
- Supporting verification planning and execution, ensuring requirements have clear verification methods and participating in testing activities
- Working hands-on during hardware bring-up and prototyping, diagnosing and resolving issues across electrical hardware, controls systems, and subsystem interfaces
- Collaborating closely with electrical, controls, mechanical, and test teams to ensure designs function correctly within the overall machine
- Supporting integration of new hardware and subsystems during development and commissioning
- Contributing to system documentation and engineering processes, including requirements management, design reviews, and integration planning
This role blends architecture development, requirements ownership, and hands-on hardware work, and is well-suited for engineers who enjoy working across disciplines while remaining closely connected to the physical system.
**REQUIREMENTS:**
- Bachelor's or Master's degree in Electrical Engineering or a related field
- 3+ years of experience in electrical systems engineering, integration, test, or hardware development
- Experience contributing to system or subsystem architecture, including defining electrical subsystems and their interactions
- Experience developing and managing technical requirements and Interface Control Documents (ICDs)
- Ability to read and interpret electrical schematics, wiring diagrams, and interconnect documentation
- Hands-on experience with hardware bring-up, troubleshooting, and root cause analysis using standard lab instrumentation such as oscilloscopes, DMMs, and logic or spectrum analyzers
- Experience working with cross-disciplinary engineering teams including electrical, controls, mechanical, and test
- Strong technical documentation and communication skills, including the ability to clearly capture requirements, interfaces, and design decisions
- Experience working with hardware suppliers or external partners to define technical requirements and review deliverables
**DESIRED SKILLS:**
- Experience in aerospace, automotive, robotics, energy systems, or other safety-critical, high-reliability industries
- Familiarity with large-scale electrical hardware systems, including power distribution, sensing, and controls integration
- Knowledge of high-voltage or high-current electrical systems, including grounding, protection, and EMI/EMC considerations
- Experience with requirements management and PLM tools such as Flow, Jama, DOORS, Teamcenter, or Confluence
- Exposure to system safety and reliability methods, including FMEA, FMECA, or fault analysis
- Experience supporting or executing system-level integration testing, including instrumentation, automation, and data analysis
- Familiarity with electrical interconnect systems and harness manufacturing standards such as IPC/WHMA-A-620 or related industry practices
- Comfort operating in fast-paced development environments where both engineering rigor and development speed are required
- Demonstrated ownership of hardware development efforts from concept through deployment, including coordination with suppliers and cross-disciplinary teams
