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 Engineering Intern
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 stagesand battery management systems ensuring our energy storage solutions are safe efficient and capable of stabilizing the worlds most demanding grids.
As an Embedded Software Engineering Internyoullwork alongside our engineers on the real-time firmware that drives our power conversion hands-on exposure to the intersection of silicon and power helping write and test low-level code that controls high-speed switching manages thermal safetyinterfaces withbattery packsand communicates with broader site infrastructure. This isa great opportunityto apply whatyouvelearned in coursework to real embedded systems that ship at scale with mentorship from experienced engineers along the way.
Responsibilities will include:
- Real-Time Control Firmware: Support the design and implementation of bare-metal software for power electronics gaining exposure to PWM generation ADC synchronization and timing logic.
- Low-Level Architecture:Assistin developing and testing drivers for microcontroller peripherals (SPI CAN Ethernet) under the guidance of senior engineers.
- Hardware-Software Collaboration: Work with power electronicscontrolsengineers to understand howcontrolstheory translates into embedded code running on Cortex-R and Cortex-M architectures.
- Battery Management Systems: Get exposure to how our power conversion firmware interfaces withreal battery packs including cell voltage/temperature monitoring state-of-charge and state-of-health estimation and the communication protocols BMS units use to report status and safety limits.
- Build & Test: Helpmaintainsoftware build scripts and write testable code gaining experience with CI/CD pipelines used tovalidatefirmware before it reaches the lab.
- System Debugging: Learn to profile and debug embedded code developing familiarity with tools like oscilloscopes logic analyzers and JTAG/SWD debuggers.
- Documentation & Process: Contribute to documentation and testing processes thatsupport takingembedded systems fromprototypetoward production.
Desired Qualifications:
- Background: Currently pursuing a BS or MS in Electrical Engineering Computer Engineering Computer Science or a related field.
- Programming Foundations: Coursework or project experience in C C or Rust; comfort reading and writing low-level code.
- Embedded Interest: Some exposure to embedded systems microcontrollers or digital logic through coursework personal projects or prior internships.
- Communication Protocols: Familiarity with concepts like SPI I2C UART or CAN is a plus even if only from classwork or personal projects.
- Battery Systems Knowledge: Exposure to battery management systems (BMS) andenergy storage fundamentals through coursework or projects is a plus though notrequired.
- Curiosity & Rigor: A safety-conscious mindset strong attention to detail and eagerness to learn how real-time safety-critical software is built.
- Bonus Qualifications: Any experience with build tools (MakeCMake) version control (git) or hands-on lab work with debugging hardware.
