About The Position

Peak Energy is seeking an experienced Embedded Software Engineer to support the development of our gigawatt-scale sodium-ion energy storage system. This role will focus on building real-time embedded firmware for critical ESS hardware and controls infrastructure. This role exists to help accelerate firmware development, hardware bring-up, and system integration as we scale our ESS platform. You will work across embedded software, electrical engineering, and systems teams to develop reliable, production-oriented firmware for safety-critical applications. You’ll contribute to embedded architecture decisions, prototype development, validation efforts, and field support while helping establish disciplined engineering and development practices across the stack. The ideal candidate thrives in fast-paced environments, enjoys solving low-level technical challenges, and takes ownership from prototype through deployment.
