The opportunity

Redwood Materials was founded in 2017 by JB Straubel, co-founder and former CTO of Tesla, on a simple but radical idea: the critical minerals powering the energy transition already exist. They just need to come back.

What you'll do

  • Own low-voltage (LV) electrical system architecture for power electronics: products, including the system controller PCBA that coordinates parallel/series-connected power converter modules

  • Design and integrate system controller hardware, including MCU selection,: communication protocols (CAN, Ethernet, etc.), and control logic for module synchronization, current-sharing, and startup/shutdown sequencing

  • Design isolated sensing circuits (current, voltage, temperature feedback) and: auxiliary power supply architecture across LV subsystems (~100W)

  • Design and coordinate protective circuits (breaker/contactor drivers,: hardware interlock/E-stop loops), ensuring insulation coordination and high-voltage safety compliance at the system level

  • Define LV wiring architecture, grounding, and interconnect strategy across: the entire product and sub power modules

  • Lead electrical testing and validation for system controller PCBA and: complete power electronics products, including power cycling, fault analysis, and performance characterization

What they're looking for

  • Collaborate with cross-functional teams (Mechanical, Controls/Firmware,: Validation, Supply Chain, Manufacturing, Reliability, Compliance) to define system requirements, test specifications, and achieve industry certifications (e.g., IEEE 1547, UL 1741)
  • BS or MS in Electrical Engineering, with a focus on embedded systems, controls, or power electronics
  • –5 years of experience in electrical engineering, with a strong focus on: system-level control architecture for power conversion or energy storage products
  • Hands-on experience designing MCU-based system controllers, including MCU: selection, memory/peripheral budgeting, and system-level control for power converters
