Power Electronics Controls Engineer, Energy Storage San Francisco, California, United States (San Francisco)

Power Electronics Controls Engineer, Energy Storage About Redwood Materials Redwood is localizing a global battery supply chain that seamlessly integrates recovery, reuse, and recycling—keeping critical minerals in circulation and driving the energy transition. Founded in 2019, we’re delivering low-cost and large-scale energy storage and producing battery materials in the U.S. for the first time, all from batteries we already have. 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. Familiar with high voltage (up to ~1,000 – 2,000VDC and 480VAC) and high power (~10 – 200kW) power converters, you can quantitatively compare and select topologies, control algorithms, semiconductors, and magnetics while respecting engineering constraints (efficiency, cost, reliability, simplicity, etc). You understand both hard- and soft-switched topologies. Responsibilities include: 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.
