Job Descriptions Hardware Engineering Roles

(Mid-Senior & Lead/Principal)

Hardware Engineer (MidSenior Level)

Position & Location: Multiple openings at various levels in Hardware and Firmware Engineering (5 years of experience).

Location: Kolkata, India

Scope: Work on platforms and products deployed globally.

Role Overview

As a Hardware Engineer, you will be a key contributor in the design, development, and validation of hardware systems for next-generation smart metering products. This includes RF design, antenna optimization, and wireless connectivity (Cellular, NB-IoT, CAT-M1, sub-GHz RF). You will lead hardware design projects, collaborate with cross-functional teams, and ensure designs meet performance, cost, quality, and regulatory compliance requirements.

Responsibilities

Hardware Design & Development

Design and develop smart water, electricity, and gas meters with Cellular, NB-IoT, CAT-M1, and RF communication systems.

Conduct sub-GHz RF circuit design, RF front-end optimization, and antenna matching/tuning.

Perform impedance matching, RF link budget analysis, and RF simulation (ADS, HFSS, CST, or equivalent tools).

Prepare Design Documents, WIS, and BoM.

Develop low-power, high-reliability, and cost-optimized PCB designs including PCD layout for RF modules.

Collaborate with firmware engineers to ensure system integration and communication protocol compliance.

Conduct RF and EMC performance validation as part of product qualification.

Prototyping & Testing

Develop and validate RF prototypes, optimizing antenna and wireless performance against product specifications.

Execute RF test performance measurements: conducted & radiated tests, sensitivity, selectivity, power output, harmonics, spurious emissions.

Validate antenna radiation patterns, return loss (S11), VSWR, and efficiency.

Perform signal integrity tests, power analysis, and component characterization.

Conduct failure analysis on RF & digital circuits, collaborating with QA for resolution.

Project Management

Manage hardware/RF design projects from concept to production release.

Lead design reviews, DFMEA/DFT/DFA/DFM/PFMEA activities.

Mentor and guide junior engineers in RF design best practices.

Support certification activities for global regulatory standards (ETSI, FCC, TRAI, BIS).

Execute design pilots and oversee transfer to manufacturing.
