* Develop and maintain firmware for embedded systems (ARM Cortex, STM32 or similar)
* Collaborate with electronics, software, and product teams to define firmware architecture
* Implement and optimise real-time control logic, sensor data processing, and communications protocols (e.g. UART, SPI, I2C, BLE, Wi-Fi)
* Write clear, maintainable, and well-documented code in C/C++
* Participate in hardware bring-up, debugging, and performance tuning
* Ensure firmware is robust, efficient, and production-ready
* Support field testing, troubleshooting, and continuous improvements


What you’ll bring


* A degree in Computer Engineering, Electronics, or related field
* Proven and demonstrable experience in embedded firmware development
* Proficiency in C/C++ for microcontrollers and real-time applications
* Familiarity with RTOS, low-power systems, and communication stacks
* A solid understanding of hardware/software integration
* Experience with debugging tools, oscilloscopes, and logic analysers
* A collaborative mindset and a passion for building things that work well


Why join NAIAD?


* £45,000 – £55,000 salary (depending on experience)
* Flexible, hybrid working—the freedom to balance home and office
* 25 days holiday plus bank holidays
* Pension scheme with company contributions
* Annual performance bonus and career development opportunities
* A key role in an ambitious, growing start-up
* A supportive, down-to-earth team working on something exciting
