Helion at a glance
Helion is building the world's first fusion power plant to deliver clean, reliable baseload electricity straight from fusion, no steam turbine required.
Helion designs and builds pulsed, field-reversed-configuration fusion machines that fire and compress plasmas to fusion temperatures and then recover the energy directly as electricity, skipping the steam-turbine step used by most other fusion and nuclear designs. Its long-term fuel is deuterium plus helium-3, aimed at smaller, cheaper, factory-buildable plants that supply always-on carbon-free power to the grid.

Summary
Design, test, and optimize high-voltage power systems for fusion generators, including energy delivery, recovery, and grid-tie infrastructure. The role involves leading system architectures, mentoring engineers, and ensuring cost-effective, scalable solutions for clean energy delivery.
Job description
About Helion
We are a fusion power company based in Everett, WA, with the mission to build the world's first fusion power plant, enabling a future with unlimited clean electricity. Our vision is a world with clean, reliable, and affordable energy for everyone.
Since Helion's founding in 2013, we have raised $1.5 billion from long-time investors such as Sam Altman, Mithril, and Capricorn Investment Group as well as new investors including Thrive Capital, LightSpeed Venture Capital, SoftBank, and others to propel us forward. Our current prototype, Polaris, has reached record-breaking plasma temperatures of 150 million degrees Celsius (13 keV). Helion is continuing to iterate and on the path to the world's first fusion power plant, Orion.
This is a pivotal time to join Helion. You will tackle real-world challenges with a team that prizes urgency, rigor, ownership, and a commitment to delivering hard truths – values essential to achieving what no one has before. Together, we will change the future of energy, because the world can't wait.
What You Will Be Doing:
You will support the core energy management systems that power Helion’s fusion generators. Your work will focus on high-power electrical systems including energy delivery to pulsed magnetics, energy recovery systems, internal redistribution networks, and grid-tie infrastructure. You will design, commission, and optimize systems that are foundational to delivering clean, low-cost electricity to the world. You will report to the Senior Manager of Electrical Engineering and this is an onsite role located at our Everett, WA office.
You Will:
- Design, test, troubleshoot, and support high-voltage power systems for pulsed magnetic coils
- Oversee design, procurement, construction, and commissioning of systems delivering <1 ms pulses up to 5 MA and 40 kV
- Develop system architectures and collaborate with designers on schematics and installation drawings
- Lead design reviews to validate cost-effective, scalable, and reliable solutions
- Support commissioning and lifetime operation of generator power systems, identifying paths to optimize future builds
- Apply rigorous engineering practices, including ownership of cost, schedule, and resource planning for assigned projects
- Mentor electrical engineers and collaborate with cross-functional teams to build technical capability across Helion
Required Skills:
- 8+ years experience in power electronics, solving complex electrical engineering problems from design to delivery
- Bachelor’s or Master’s degree in Electrical Engineering, Physics, or a related field
- Experience designing, fabricating, installing, and testing electronic systems
- Strong knowledge of solid-state switching technologies and power components such as IGBTs, MOSFETs, and SCRs
- Technical depth in engineering principles, codes, and practices with experience coordinating deliverables to meet milestones
- Advanced troubleshooting skills with standard benchtop tools (oscilloscopes, E-loads, pulse generators, spectrum analyzers) and PCB design software
- Proficiency with tools such as Microsoft Office, LTSpice, SIMetrix/SIMPLIS, Altium, and MATLAB
