Senior Electrical Engineer, Pulsed Power

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 $600 million from investors such as Sam Altman, Mithril, and Capricorn Investment Group 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).

Now we are working toward Polaris, which will be the first machine to demonstrate electricity from fusion, making this a great time to join Helion! Bring your skills, experiences, and determination to make a difference in the world. Together, we can make a future with unlimited clean electricity from fusion a reality.

What You Will Be Doing

We are hiring an Electrical Engineer to support the core of the world's first fusion generator machine. You will support the main pulsed-energy drive systems for the magnetics, the energy recovery and re-distribution networks, the diagnostics, and the controls. You will also develop novel ways to measure and acquire this data from high noise, high field, and high voltage environments. You will report directly to our Electrical Engineering Manager at our Everett, WA office.

You Will:

• Lead the development and commissioning 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 for system upgrades
• Select components to develop cost-effective, scalable, and reliable design solutions and lead design reviews of developed systems
• Collaborate with end-users and operators of power systems to complete commissioning efforts and survey opportunities to upgrade designs
• Produce plans, typically long-term, for solution development, documentation, and deployment while meeting several compliance, reporting, and safety standards following established engineering procedures in an evolving environment
• Produce cost and schedule estimates related to the electrical system design, procurement, and installation
• Develop technical requirements and work scopes for suppliers and subcontractors while functioning as an advisor or project leader providing direction to less experienced professional staff

Required Skills

• 7+ years of experience in power systems engineering or in high-power, high-voltage pulsed DC systems up to 40kV, especially within the system requirement and design phases
• Experience in design, fabrication, installation, and test of high-voltage electronics
• Mastery of 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, 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 like oscilloscopes, Eloads, FRA, Arb waveform generators, pulse generators, spectrum analyzers, DVMs, schematic capture, and PCB design software
• Experience with Microsoft Suite, LTSpice, SIMtrex/Simplis, KiCAD, Altium, Matlab

Benefits and Compensation

Our total compensation package includes generous equity and benefits, including but not limited to:

• Medical, Dental, and Vision plans for employees and their families
• 31 Days of PTO (21 vacation days and 10 sick days)
• 13 Paid holidays, plus company-wide winter break
• Up to 5% employer 401(k) match
• Short term disability, long term disability, and life insurance
• Paid parental leave and support (up to 16 weeks)
• Annual wellness stipend
