Responsibilities
You will be an early member of a product design team, responsible for the detailed power electronics design, prototype, and launch into high-volume production of an efficient, cost effective, highly manufacturable, and technologically leading-edge power converter
You can create highly accurate time-domain control and thermal models of your circuits to inform software and mechanical development, and while your core specialty is high-power circuitry design, you have a working understanding of microprocessor selection, electrical insulation, and thermal interface
Knowing how important circuit board layout is in high-power conversion, you're willing to jump in and do the most critical parts of the powertrain layout yourself
