Job description
We are seeking an experienced Embedded / Firmware Developer (3–8 years) to design, develop, and maintain high-performance firmware for next-generation smart metering solutions. In this role, you will focus on 3-phase meter development, metrology calibration, and advanced communication protocols to strengthen our core development team. Key Responsibilities Firmware Design: Develop, test, and debug low-level embedded software using C/C++ on micro controllers (e.g., ARM Cortex, TI, Renesas). Metering & Metrology: Implement and calibrate metrology algorithms for accuracy in 1Ph and 3-phase energy measurement. Protocol Integration: Integrate and maintain DLMS/COSEM communication protocols and smart grid standards. Tamper Management: Design firmware logic for robust tamper detection, anti-theft mechanisms, and event logging. Hardware Interfacing: Write drivers for SPI, I2C, UART, ADC, RTC, and external flash memories. Contribute to the design and implementation of new features and functionality. Participate in code reviews and provide feedback on best practices. Troubleshoot issues related to hardware, software, and system integration. Required Qualifications Experience: 3 to 8 years of hands-on experience in embedded C/C++ firmware development. Domain Expertise: Proven track record in the electricity metering industry (specifically 3-phase meters). Protocol Knowledge: Deep understanding of the DLMS/COSEM protocol stack. Core Skills: Solid experience with metrology processing, power management, and tamper-handling logic. Tools: Proficiency with oscilloscopes, logic analyzers, and hardware debuggers (JTAG/SWD).
