About the role

  • 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.
  • You will be responsible for bringing new products from white-space R&D to global scale, ensuring our code is as resilient as the hardware it controls.
  • In accordance with California pay transparency laws, the salary range for this position is listed below.

Responsibilities

  • Our Embedded Software team is responsible for the intelligence that drives our power stages, ensuring our energy storage solutions are safe, efficient, and capable of stabilizing the world's most demanding grids.
  • As an Embedded Software Engineer, you will be the architect of the real-time firmware that drives our power conversion units.
  • You will live at the intersection of silicon and power, writing the low-level code that controls high-speed switching, manages thermal safety, and communicates with the broader site infrastructure.
  • Design and implement bare-metal software applications for power electronics, focusing on high-resolution PWM generation, ADC synchronization, and complex timing logic.
  • Develop and optimize drivers for microcontroller peripherals (SPI, CAN, Ethernet) and architect memory-efficient, multi-core processing strategies for real-time targets.
  • Collaborate with power electronics controls engineers to translate controls theory into deterministic, high-performance code running on Cortex-R and Cortex-M architectures.
  • Maintain robust software build procedures and scripts.

Requirements

  • Background: A BS or MS in Electrical Engineering, Computer Engineering, or Computer Science, combined with 2+ years of experience in firmware engineering and a proven track record of shipping new products at scale.
  • Embedded Mastery: Expert proficiency in Rust or C with deep experience debugging complex embedded systems using oscilloscopes, logic analyzers, and JTAG/SWD debuggers.
  • Silicon Expertise: Extensive experience with ARM Cortex-M and Cortex-R architectures, including low-level system architecture, multi-core memory optimization, and bare-metal task management.
  • Experience with test automation and CI/CD is essential.

Nice to have

  • A safety-centered mindset with experience implementing functional isolation and ensuring freedom from interference (FFI) in complex, multi-core software environments.
  • Familiarity with UL certification standards for energy storage systems is a significant plus.
  • Practical experience with digital protocols such as I2C, UART, SPI, CAN/CAN-FD, and Ethernet.
  • Safety-Critical Development: A safety-centered mindset with experience implementing functional isolation and ensuring freedom from interference (FFI) in complex, multi-core software environments.
  • Communication Protocols: Practical experience with digital protocols such as I2C, UART, SPI, CAN/CAN-FD, and Ethernet.

Compensation

  • $180,000 - $237,500 USD
  • Compensation will be commensurate with experience.

Company info

  • Founded in 2017, 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.
  • We are at the precipice of a global energy transition.
  • At Redwood Materials, we are moving beyond battery recycling to build the most advanced, circular energy ecosystem on the planet.
  • Our goal is to move the industry away from static, hardware-heavy infrastructure toward agile, software-controlled energy assets.
  • While others build "black box" hardware, we are building software-defined power systems.
