Job Purpose

To own the layout and physical design of our smart energy meters (single-phase, three-phase, and CT/HT variants). You will take designs from schematic to production, working closely with hardware, firmware, EMC, and manufacturing teams to deliver reliable, compliant, and cost-optimized boards for large-scale utility deployments.

Preferred Competency

- RF and antenna layout experience (sub-GHz, 2.4 GHz, cellular).
- SI/PI simulation tools (HyperLynx, Ansys SIwave, Sigrity).
- Experience with PLM/ECN processes and version control for hardware.
- Exposure to high-volume manufacturing, panelization, and test fixtures (ICT/FCT).
- Knowledge of thermal simulation and design for harsh outdoor conditions (high humidity, surge, temperature extremes).
- Basic scripting for design automation (Python, SKILL, or Altium scripts).

Experience: 7-10 years of hands-on PCB design experience, with at least 3-4 years in metering, energy, or industrial electronics.

Key Responsibilities

- Lead PCB layout for mixed-signal smart meter boards, covering metrology (energy measurement AFE/SoC), MCU, power supply (SMPS/capacitive/transformer), communication modules, display, and relay driver sections.
- Plan stack-ups, component placement, routing, and board partitioning to achieve accuracy, noise immunity, and EMI/EMC performance.
- Apply design practices for high-voltage and safety compliance, including creepage and clearance, isolation barriers, surge/ESD protection, and tamper-resistant layouts.
- Design for communication interfaces such as RF mesh, NB-IoT/LTE-M/GPRS, PLC, Wi-SUN,



Zigbee, optical port, and RS-485, including antenna layout and RF keep-outs.
- Run pre- and post-layout checks (DRC, SI/PI where applicable) and support thermal analysis for compact, sealed enclosures.
- Develop and maintain component libraries (footprints, 3D models) following IPC standards.
- Collaborate with mechanical teams on enclosure fit, connector placement, and terminal block integration.
- Release complete manufacturing packages (Gerber/ODB++, BOM, assembly drawings, fabrication notes) and support DFM/DFT/DFA reviews with EMS partners.
- Support prototype bring-up, debugging, failure analysis, and design iterations after EMC and type testing.
- Contribute to cost-down initiatives, alternate component qualification, and design reuse across product platforms.
- Mentor junior designers and enforce layout guidelines and review checklists.

Key Skills:

- Solid proficiency in at least one major EDA tool (Altium Designer, Cadence Allegro/OrCAD, or Mentor PADS/Xpedition).
- Solid understanding of mixed-signal layout: grounding strategies, shielding, low-noise analog routing, and current/voltage sensing paths (shunt, CT, Rogowski).
- Working knowledge of IPC-2221/2222/7351/A-610 and DFM/DFA guidelines.
- Experience with multilayer, HDI, and high-voltage board design.
- Familiarity with relevant standards: IS 16444, IS 15959, IS 13779, IEC 62052/62053, IEC 61000 series, and CEA/BIS requirements.
- Good understanding of EMI/EMC principles and experience fixing failures at pre-compliance or lab level.
