Helion is building the world's first fusion power plant to deliver clean, reliable, and abundant electricity to the grid. Backed by Lightspeed, Peak XV and SoftBank VF.
About the role
For a power electronics engineer, that makes this a rare kind of role. You'll take designs from concept through bring-up, commissioning, and operation on a working fusion machine, owning real outcomes, not a narrow slice of someone else's system. Small teams and fast build-test-learn cycles mean your decisions reach hardware in weeks, not years.
What they're looking for
- A degree in Electrical Engineering or a related field, or equivalent hands-on experience
- A solid grounding in power electronics fundamentals: switching topologies, semiconductor device selection (IGBTs, MOSFETs, thyristors/SCRs), gate drive, magnetics, thermal design, and loss analysis
- Proficiency with PCBA design (Altium, KiCad, or equivalent) and circuit simulation (SIMetrix, PLECS, LTspice, PSIM, or equivalent)
- Strong hands-on lab skills: bench bring-up, characterization, and debugging with oscilloscopes, DMMs, and related instrumentation
- Comfort working across the hardware–firmware boundary, familiarity with real-time interfaces such as EtherCAT and with FPGA or embedded monitoring is an asset
- High-voltage or pulsed-power experience is welcome but not required. We actively support strong power electronics engineers in growing into our high-voltage and pulsed-power work
More about this role
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.
Fusion happens in the power electronics. At Helion, plasma is compressed to fusion conditions by pulsed electromagnetic fields, so the machine's performance is,...
