Embedded Software Engineer Intern - Fall 2026

Redwood Materials is localizing a global battery supply chain that integrates recovery, reuse, and recycling to drive the energy transition. As an Embedded Software Engineering Intern, you'll work with engineers on real-time firmware for power conversion units, gaining hands-on experience in embedded systems and contributing to the development of software-defined energy solutions.

What you'll do:

• Support the design and implementation of bare-metal software for power electronics, gaining exposure to PWM generation, ADC synchronization, and timing logic
• Assist in developing and testing drivers for microcontroller peripherals (SPI, CAN, Ethernet) under the guidance of senior engineers
• Work with power electronics controls engineers to understand how controls theory translates into embedded code running on Cortex-R and Cortex-M architectures
• Get exposure to how our power conversion firmware interfaces with real 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
• Help maintain software build scripts and write testable code, gaining experience with CI/CD pipelines used to validate firmware before it reaches the lab
• Learn to profile and debug embedded code, developing familiarity with tools like oscilloscopes, logic analyzers, and JTAG/SWD debuggers
• Contribute to documentation and testing processes that support taking embedded systems from prototype toward production

What they're looking for:

• Currently pursuing a BS or MS in Electrical Engineering, Computer Engineering, Computer Science, or a related field
• Coursework or project experience in C, C++, or Rust; comfort reading and writing low-level code
• Some exposure to embedded systems, microcontrollers, or digital logic through coursework, personal projects, or prior internships
• A safety-conscious mindset, strong attention to detail, and eagerness to learn how real-time, safety-critical software is built
• Familiarity with concepts like SPI, I2C, UART, or CAN is a plus, even if only from classwork or personal projects
• Exposure to battery management systems (BMS) and energy storage fundamentals through coursework or projects is a plus, though not required
• Any experience with build tools (Make, CMake), version control (git), or hands-on lab work with debugging hardware
