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 recent 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).
