We're looking for an Embedded Firmware Engineer to help design and implement the low-level software that runs on our embedded platforms. You'll develop firmware to interface with microcontrollers, implement real-time control algorithms, and work closely with hardware and systems teams to ensure seamless integration. This role is perfect for someone who enjoys writing high-quality C code, diving into registers and datasheets, and building reliable, production-grade embedded systems.

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 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 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
