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 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. 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. 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 and optimize drivers for microcontroller peripherals (SPI, CAN, Ethernet) and architect memory-efficient, multi-core processing strategies for real-time targets. * Hardware-Software Synergy: Collaborate with power electronics controls engineers to translate controls theory into deterministic, high-performance code running on Cortex-R and Cortex-M architectures. * 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, ensuring maximum task efficiency and minimal latency in time-critical control loops. * Product Scaling: Leverage a proven track record to take embedded systems from initial prototype to mass-market production, maintaining high standards for code quality and reliability. ## Related Videos - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Code to Road in < 12 hours](https://www.wearedevelopers.com/videos/1082-code-to-road-in-12-hours) - [The Gashlycrumb Tinies of AI Networking You Must Know (or Languish!)](https://www.wearedevelopers.com/videos/2067-the-gashlycrumb-tinies-of-ai-networking-you-must-know-or-languish) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [Unleashing the Full Potential of the Arm Architecture – Write Once, Deploy Anywhere](https://www.wearedevelopers.com/videos/940-unleashing-the-full-potential-of-the-arm-architecture-write-once-deploy-anywhere) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) ## Related Articles - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Top Characteristics of a Software Engineer](https://www.wearedevelopers.com/magazine/166-top-characteristics-of-a-software-engineer) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
