Principal Software Engineer - Embedded/Firmware

Job Summary

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.

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).
