• As a Principal Capacitor Design Engineer at Helion, you will lead the design, development, and scaling of custom high-voltage, pulsed-power capacitors that are core to Helion’s fusion generators. You will own capacitor architecture from first principles through high-volume manufacturing, driving breakthroughs in energy density, reliability, and cost. You will provide deep technical leadership to engineering, manufacturing, and production teams as Helion transitions from prototype builds to the world’s first fusion power plant. You will provide technical leadership, organize work, set priorities, and advance Helion’s mission to deliver clean power in a reliable and cost-effective manner. This role is onsite at our headquarters in Everett, WA.
• Lead the full lifecycle of capacitor development—requirements definition, physics-based modeling, internal design, materials selection, prototyping, testing, and scaling into high-throughput manufacturing
• Drive the development of low-inductance, high-reliability pulsed capacitors capable of
