The role requires hands-on experience in end-to-end hardware product development, from concept and design through validation, certification, manufacturing, and production support. Please find the detailed job responsibilities and required skills below.
Responsibilities:
· Design and develop analog, digital, and mixed-signal hardware for Digital/Numerical Protection Relays (IEDs) from concept through production.
· Design precision analog front-end circuits for CT/PT current and voltage measurement, signal conditioning, amplification, filtering, and high-resolution ADC interfaces.
· Design isolated AC/DC and DC/DC power supplies, SMPS, and protection circuits with appropriate thermal and reliability considerations.
· Develop embedded hardware using ARM/DSP processors, FPGAs, ADCs, memory interfaces, and industrial communication peripherals.
· Perform schematic design, component selection, design calculations, PCB review, and hardware validation.
· Design and implement communication interfaces, including 100/1000BASE-T Ethernet (RJ45), fibre-optic Ethernet, RS422 and RS-485, with support for industry-standard protocols such as IEC 61850, IEC 60870-5-103, and DNP3
· Ensure compliance with IEC 60255, IEC 61000, IEC 61850, CE, EMC/EMI, and other applicable industry standards through design verification and testing.
· Perform hardware debugging, root cause analysis, design verification, type testing, and field failure investigations using standard laboratory equipment.
· Support manufacturing, product release, engineering documentation, BOM management, and production issue resolution throughout the product lifecycle.
· Develop reliable, high-performance, and maintainable hardware designs with a focus on manufacturability, component lifecycle, and long-term product support.
· Stay current with emerging hardware technologies, components, and design practices to continuously improve product performance and quality.
Skills and Qualifications:
· B.E./B.Tech or M.E./M.Tech in Electronics & Communication, Electrical, Instrumentation, or related discipline with 10 to 15 years of hands-on experience in hardware design and product development.
· Strong expertise in Analog & Power Electronics, including CT/PT interfaces, signal conditioning, ADCs, isolated power supplies, and embedded hardware.
· Hands-on experience with ARM/DSP processors, FPGAs, DDR/NOR/NAND Flash, Ethernet, RS422, RS485 and industrial communication protocols such as IEC 61850, IEC 60870-5-103, and DNP3.
· Proficiency in Cadence OrCAD Capture, Cadence Allegro PCB Designer, LTspice EDA Tools and schematic design, PCB review, hardware validation, and debugging using standard laboratory equipment.
· Good understanding of EMC/EMI, electrical isolation, surge protection, reliability engineering, and compliance with IEC 60255, IEC 61000, and other relevant industry standards.
· Experience in Digital/Numerical Protection Relays, Substation Automation, Smart Grid, or Electrical Power System products with strong analytical, troubleshooting, documentation, and cross-functional collaboration skills.
