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 over $1 billion from long-time investors such as Sam Altman, Mithril, and Capricorn Investment Group as well as new investors SoftBank and Lightspeed to propel us forward. Our last prototype, Trenta, completed 10,000 high-power pulses and reached plasma temperatures of 100 million degrees Celsius (9 keV). We are now operating Polaris, our next prototype on the path to the world's first fusion power plant.

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 play a critical role in supporting the core electrical energy management systems that power our fusion generators. This includes systems responsible for energy delivery to magnetics, fusion energy recovery, and redistribution networks. This onsite role reports directly to the Senior Manager of Electrical Engineering at our Everett, WA office.

You Will:

Design, test, troubleshoot, and support operation of high voltage electrical power systems for driving pulsed magnetic coils
Oversee design, procurement, construction, and commissioning of high-power electrical systems to drive pulsed coils (<1ms) at currents up to 5MA and voltages up to 40 kV
Develop electrical system architecture and work with designers to produce electrical schematics and installation drawings
Develop cost-effective, scalable, and reliable design solutions via technical peer review through a design review process for each major design project
Collaborate with operators of generator power systems through machine commissioning and, for development machines, through the lifetime of the machine
Demonstrate rigorous engineering practices including management of cost, schedule, and resource estimates as they pertain to your design, build, and delivery timelines

Required Skills:

5+ years experience in power electronics, solving complex electrical engineering problems from design to delivery
Bachelor's or Master's level degree in Electrical Engineering, Physics, or a related technical field
Experience in design, fabrication, installation and test of electrical systems
Strong background with solid state switching technologies and understanding of operating characteristics of power electronic components such as IGBTs, power MOSFETs, and SCRs
Technical expertise in the application of engineering concepts, principles, codes, and theory, and practice with the ability to coordinate workloads to meet established deadlines or milestones with some experience in project leadership
Advanced in electronic troubleshooting systems using standard benchtop tools such as oscilloscopes, Eloads, pulse generators, spectrum analyzers, and PCB design software
Experience with Microsoft Suite, LTSpice, SIMtrex/Simplis, Altium, Matlab
