Power Electronics Engineer, R&D

Own the electrical design of the machine’s power path: the DC bus, the inverter, the motor drive, and the amplifiers driving the magnetic bearings around the rotor.

Specify and integrate the drive for a high-speed hermetic motor, including the switching, thermal, bearing-current and insulation questions that follow from running a machine fast.

Design the power and protection scheme for the test benches and the load bank, so a machine can be run to full rating and its output absorbed or regenerated.

Take the electrical scope through EMC, harmonics and arc flash to an installation that is safe to work on and safe to sign off.

Own electrical safety in the test cell, including the procedures the technicians and test engineers work to around live buses and stored energy.

The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would .

You’ve designed a high-power converter or motor drive that got built, and you were there the first time it drove a real load.

You’ve integrated a drive with a motor somebody else designed, and dealt with what the drive then did to the machine and to everything sharing the bus.

You’ve chased an EMC, harmonic or bearing-current problem to its actual cause instead of adding a filter and hoping.

You’ve written electrical safe work practices and then enforced them on people who found them inconvenient.

You’ve powered up a test cell or a first-of-a-kind installation, and you were the one who decided it was safe to close the breaker.

Bonus: High-speed and magnetic-bearing drive systems. Electric propulsion and aerospace power systems (eVTOL, satellite EPS, electric pump-fed engines). 800 V class DC architectures and wide-bandgap devices (SiC, GaN). Test cell power and safe practice around energized work (test benches, load banks, regenerative drives).

We are committed to pay equity and transparency.
