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 current 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).
