* Implement and ensure compliance with the MID (Measuring Instruments Directive - 2014/32/EU), RED 18031 cyber regulation and other relevant standards.
* Collaborate with hardware engineers on board bring-up, component selection, and system integration.
* Develop low-level drivers for peripherals such as SPI, I2C, UART, ADC, and timers.
* Write clean, readable, and well-documented code, adhering to industry best practices like MISRA C.
* Create and execute unit tests and validation plans to ensure firmware robustness and reliability.
* Debug and resolve complex issues that involve both hardware and software interaction, using tools like JTAG/SWD debuggers, oscilloscopes, and logic analyzers.
* Participate in code reviews to maintain high standards of quality and share knowledge within the team.
* Contribute to technical documentation, including design specifications and test reports.
Technical Skills & Qualifications
Essential:
* Bachelor’s or Master’s degree in Electrical Engineering, Computer Science, or a related field.
* 3+ years of professional experience in embedded firmware development.
* Proven expertise in C/C++ programming for 32-bit microcontrollers, with a strong focus on the STMicroelectronics STM32 series.
* Hands-on experience with real-time operating systems (RTOS), such as FreeRTOS.
* Solid understanding of microcontroller peripherals and communication protocols (I2C, SPI, UART, CAN, etc.).
* Demonstrable knowledge and experience with the MID Directive, BS EN 50470, RED 18031 cyber regulation and Welmec 7.2, particularly its application to active electrical energy meters.
* Proficiency with debugging tools (e.g., GDB, JTAG/SWD debuggers) and measurement equipment (oscilloscopes, logic analyzers).
Advantageous:
* Prior professional experience in the electric meter or sub-metering industry.
* Experience with similar ARM-based microcontroller platforms from vendors such as:
* NXP (LPC series)
