Principal Hardware Engineer

Job Summary

We are looking for a Lead/Principal Hardware Engineer with strong hands-on experience in smart electricity meter hardware design and development. The role will involve owning the end-to-end hardware design and validation of single-phase and three-phase electricity meters, including Whole Current (WC), Low-Tension Current Transformer (LTCT), and High-Tension Current Transformer (HTCT) variants. The successful candidate will be responsible for schematic design, multi-layer PCB design, metrology circuits, power supplies, hardware bring-up, debugging, validation, and supporting EVT/DVT/PVT builds through production.

Responsibilities

• Lead the design and development of metering hardware based on energy measurement AFE/ICs, for single-phase and three-phase applications.
• Design current-sensing front ends appropriate for WC, LTCT, and HTCT meter variants using shunts, current transformers (CTs), and Rogowski coils, as applicable.
• Perform schematic capture and multi-layer PCB design using Altium Designer and/or Cadence OrCAD/Allegro, Mentor PADS, or KiCad.
• Own component selection, BOM development, PCB stack-up definition, design-for-manufacturing (DFM), and design-for-test (DFT) activities.
• Design and validate metering power supplies, including SMPS and/or capacitive dropper power supplies, as applicable to the product architecture.
• Implement surge, ESD, EFT, and other protection mechanisms required for reliable meter operation and regulatory compliance.
• Lead hardware bring-up, debugging, characterization, and validation, activities from prototype through production.
• Plan and execute EVT, DVT, and PVT builds in collaboration with EMS/CM partners.
• Define and support the development of production jigs, fixtures, automated/manual test stations, and hardware validation setups.
• Work closely with firmware, software, mechanical, manufacturing, quality, and certification teams to resolve hardware and system-level issues.
• Support regulatory and certification testing, including accuracy, type testing, EMC/immunity, surge, ESD, and environmental qualification.

Requirements

• Required Qualifications B.E./B.Tech/M.E./M.Tech in Electronics Communication Engineering (ECE), Electrical Electronics Engineering (EEE), or a related discipline.
• 6+ years of relevant experience in electronics hardware design, preferably with significant experience in smart electricity meters or metering equipment.
• Demonstrated experience taking hardware products through the complete development lifecycle, from architecture and schematic design through PCB development, prototype bring-up, validation, certification, and production.
