FirmwareEngineer

Fuse Energy is a forward-thinking renewable energy startup on a mission to deliver a terawatt of renewable energy - fast. We're combining first-principles thinking with cutting-edge technology to build a radically better energy system. We raised $170M from top-tier investors including Multicoin, Balderton, Lakestar, Accel, Creandum, Lowercarbon, Ribbit, Box Group and strategic angels like Nico Rosberg, the Co-Founder of Solana and GPs behind Meta, Revolut, Spotify, Uber and more. We’re creating a fully integrated energy company: from developing solar, wind and hydrogen projects to real-time power trading and distributed energy installations. By selling directly to consumers, we cut out the middleman, lower costs and pass on savings to customers. But we’re not stopping there. We’re also building the Energy Network: a decentralised platform of smart devices that rewards users in Energy Dollars for electrifying their homes, shifting usage to off-peak hours, and helping balance the grid. This network strengthens grid stability - a critical foundation for scaling AI data centers and other energy-intensive industries. ### Responsibilities * Develop low-level firmware and drivers for microcontrollers and embedded peripherals (SPI, I2C, UART, DMA, ADC, etc.) * Design and implement real-time control software and embedded algorithms for energy devices * Write, test, and debug embedded C/C++ firmware running on bare-metal or RTOSbased systems * Collaborate with hardware, systems and controls teams to define firmware requirements and test plans * Participate in code reviews, write documentation and contribute to the continuous improvement of firmware practices * Assist in board bring-up, profiling and debugging using tools like oscilloscopes, JTAG/SWD, and logic analysers * Implement and maintain bootloaders, linker scripts and firmware deployment pipelines **Requirements** * 2+ years of experience in embedded systems or firmware engineering * Strong proficiency in C, with expe
