Overview:\n\nDesign, develop, and optimize metrology firmware for single-phase/three-phase energy meters, focusing on energy computation (active/reactive/apparent energy, power, RMS).\n\nKey Responsibilities:\n\n- Take a metrology firmware module from architecture to certified product (IEC/ANSI accuracy class compliance, type testing).\n\n- Perform RMS calculation, power factor analysis, harmonics, sampling theory, and calibration (gain/phase/offset).\n\n- Configure metrology ICs/SoCs (e.g., Analog Devices ADE7xxx/ADE9xxx, STPM3x, Renesas, TI) via register-level programming and SPI/UART/I2C.\n\n- Develop low-level drivers and work with RTOS (FreeRTOS).\n\n- Debug using oscilloscopes, reference meters, logic analyzers, and JTAG/SWD.\n\n- Mentor junior engineers and collaborate with cross-functional teams (hardware, QA, product).\n\nRequirements:\n\n- 10+ years of hands-on embedded firmware experience with C/C++.\n\n- 35 years specifically in metrology/energy-metering firmware development.\n\n- Knowledge of metering standards: IEC 62053-21/22/23, IEC 62052-11, and/or ANSI C12.20.\n\n- Experience with calibration and production test tooling.\n\nNice-to-Have:\n\n- Experience with smart meter protocols (DLMS/COSEM, Modbus, RF mesh, PLC).\n\n- Knowledge of tamper detection algorithms and anti-fraud logic.\n\n- Familiarity with functional safety/security (secure boot, firmware signing).\n\n- Proficiency in MATLAB/Python for algorithm validation.\n\nTeam & Working Model:\n\n- Work alongside a domain expert and metrology consultant.\n\n- Lead/mentor a team of embedded engineers.\n\n- Report to Engineering Manager.\n\nSkills\nEmbedded System, C, Firmware, C++, Device Driver, RTOS, SmartMeter","description_format":"text","description_chars":1668,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-26T00:07:01Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long
