What You Will Be DoingOur power electronics work spans three focus areas. Depending on your background, interests, and level, you may go deep in one or work across several - many of our engineers own problems that touch all three.
Controls & protection for the power stage. Design the low-voltage electronics that command, monitor, and protect the pulsed-power circuits - EtherCAT-networked control boards that command charge and dump, synchronize triggering across many switches, capture high-speed diagnostics inside a high-voltage environment, and drive the fault protection that keeps a multi-megajoule system safe. This spans precision analog sensing, digital logic, FPGA-based monitoring, driver circuits, and dynamic snubbing.
High voltage & pulsed power. Design, build, and commission the pulsed-power systems that compress plasma to fusion conditions - capacitor banks, switching (thyristor/SCR and solid-state), triggering, and protection at kilovolt and kiloampere scale with sub-millisecond pulses. Characterize components under real pulsed conditions and turn test data into design guidance the team relies on.
Power electronics design. Design the power-conversion hardware that charges, controls, and recovers energy across the machine - high-efficiency converters, chargers, and energy-recovery circuits. Select devices, design magnetics and thermal paths, and optimize for efficiency, density, and manufacturability as we scale from prototype toward a production power plant.
Required Skills- A degree in Electrical Engineering or a related field, or equivalent hands-on experience.
- Demonstrated experience designing and building power electronics or power-conversion hardware - from schematic through board bring-up, debug, and test. (The depth and independence we look for scale with level: from owning defined circuits and boards, to owning complex, loosely-defined systems, generating requirements for others, and setting technical direction.)
- 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.
Tools matter less than capability. If you've done the equivalent work in a different tool or stack, tell us - we care about what you can design and debug, not which software you learned it in.
