The opportunity

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 2017, we’re delivering low-cost and large-scale energy storage and producing battery materials in the U.

What you'll do

  • Design high-voltage (800V–1.5kVdc, 480–800Vac) and high-power (10kW–200kW): converters tailored for utility-scale BESS and industrial infrastructure.

  • Conduct comprehensive topology comparison and trade-off analyses evaluating: efficiency, power density, cost, and manufacturability.

  • Perform power-stage component sizing and Si/SiC MOSFET selection based on: loss modeling and thermal management.

  • Design robust gate driver circuits and dedicated gate driver power supplies: to ensure safe, high-frequency switching operations.

  • Lead the design, modeling, and specification of custom magnetic components,: including transformers and inductors utilizing Litz-wire or PCB-winding architectures.

  • Architect the low-voltage (LV) subsystem, including auxiliary power supplies,: sensing circuitry (voltage/current/temperature), and hardware-level protection.

What they're looking for

  • Design and optimize EMI filters, including differential-mode and common-mode: inductors, X/Y-caps, and damping elements.
  • Drive high-voltage, high-power PCB/PCBA layout design, ensuring: clearance/creepage rules and signal integrity under high-noise environments.
  • Review, define, and amend system requirements for power electronics products.
  • Work with the Mechanical Engineering team to optimize cooling methods and: thermal stack-up analysis and product geometry.
