About Redwood Materials
Redwood is localizing a global battery supply chain that seamlessly integrates recovery reuse and recyclingkeeping critical minerals in circulation and driving the energy transition. Founded in 2017were 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.
Embedded Software Engineer Power Electronics
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. Our Embedded Software teamis responsible forthe intelligence that drives our power stages ensuring our energy storage solutions are safe efficient and capable of stabilizing the worlds most demanding grids.
As anEmbedded 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. You willbe responsible forbringing new products from white-space R&D toglobalscale ensuring our code is as resilient as the hardware it controls.
Responsibilities will include:
- Real-Time Control Firmware:Design and implement bare-metal software applications for power electronics focusing on high-resolution PWM generation ADC synchronization and complex timing logic.
- Low-Level Architecture:Develop andoptimizedrivers for microcontroller peripherals (SPI CAN Ethernet) and architect memory-efficient multi-core processing strategies for real-time targets.
- Hardware-Software Synergy:Collaborate with power electronicscontrolsengineers to translatecontrolstheory into deterministic high-performance code running onCortex-RandCortex-Marchitectures.
- Modern Build & Test:Maintain robust software build procedures and scripts. You will write highly testable code and integrate it into a modern CI/CD pipeline to ensure every line of code is validated before it hits the lab.
- System Optimization:Profile and optimize code across multi-core environments ensuringmaximumtask efficiency and minimal latency in time-critical control loops.
- Product Scaling:Leveragea proventrack recordto take embedded systems frominitialprototype to mass-market productionmaintaininghigh standardsfor code quality and reliability.
Desired Qualifications:
- Background:A BS or MS in Electrical Engineering Computer Engineering or Computer Science combined with 2 years of experience in firmware engineering and a proventrack recordof shipping new products at scale.
- Embedded Mastery:Expertproficiencyin Rust orC 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.
- Power ElectronicsLiteracy:A deep understanding of power-specific software requirements specifically high-speed ADC sampling high-resolution PWMs and hardware timers.
- Safety-Critical Development: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.
- Communication Protocols:Practical experience with digital protocols such asI2C UARTSPICAN/CAN-FD and Ethernet. Familiarity with reverse-engineering CAN protocols or developing custom evaluation tools is a significant plus.
- Infrastructure & Automation:Knowledge of software build systems and the ability tomaintainbuild scripts (). Experience with test automation and CI/CD is essential.
- Bonus Qualifications: Experience developing bootloaders implementing secure boot or profiling code on real-time multi-core targets.
