Senior Firmware Engineer

We're seeking a Senior Firmware Engineer to join our team. As a key member of our engineering team, you will develop low-level firmware and drivers for microcontrollers and embedded peripherals. You will design and implement real-time control software and embedded algorithms for energy devices. Your expertise will help us build a radically better energy system.

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 RTOS-based 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

Requirements:

• 5+ years of experience in embedded systems or firmware engineering
• Strong proficiency in C, with experience writing firmware for microcontrollers
• Hands-on experience with common MCU peripherals: SPI, I2C, UART, DMA, timers, ADCs, Flash, CAN, etc.
• Experience working with real-time systems and embedded development toolchains (e.g., GNU, IAR)
• Familiarity with version control and tooling (e.g., Git, Docker, CI pipelines)
• Ability to work with hardware debugging tools (oscilloscopes, logic analysers, JTAG/SWD)

Bonus:

• Experience with power electronics or grid-connected converter controls
• Knowledge of control systems and digital signal processing (FIR, IIR, FFT)
• Familiarity with embedded bootloaders, memory maps and linker scripts

Experience with board bring-up and low-level hardware/software integration

Benefits:

• Competitive salary and an equity sign-on bonus
• Biannual bonus scheme
• Fully expensed tech to match your needs
