Hardware Engineer (Mid–Senior Level)
Position & Location : Multiple openings at various levels in Hardware and Firmware Engineering (5–10 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
