RADWIN | Chennai, India | Full time The Role RADWIN is looking for a hands-on Senior Hardware Engineer to develop next-generation wireless platforms based on Qualcomm networking SoCs, ARM-based processors, and FPGAs. Reporting to the Platform Group Manager, you will take technical ownership of digital and power hardware development, from architecture and schematic design through board bring-up, validation, and production. You will work closely with RF and antenna, mechanical, software, firmware, compliance, and manufacturing teams. Responsibilities
• Develop hardware architectures, block diagrams, and detailed designs, taking projects from concept through mass production.
• Design processor-based boards using Qualcomm SoCs and other ARM-based processors, including DDR memory, flash, PCIe, USB, Ethernet/SerDes interfaces, clocking, and reset circuits.
• Design power systems, including multi-rail PMICs, DC/DC converters, power sequencing, PoE (PD/PSE), protection circuits, and power budgets for outdoor products operating across wide temperature ranges.
• Develop FPGA board designs, including device selection, pin planning, configuration, high-speed interfaces, and integration with FPGA and firmware engineers.
• Create and maintain schematics in OrCAD Capture. Guide PCB layout, define stack-up and signal
- and power-integrity constraints, and review component placement and routing.
• Perform signal-integrity, power-integrity, and thermal analyses, validating results against lab measurements.
• Bring up and debug complex boards with software and firmware teams using oscilloscopes, logic and protocol analyzers, JTAG, and power analyzers.
• Define and execute hardware design verification tests, including margin, temperature, power, and reliability testing. Support EMC, surge, and safety qualification.
• Work with Qualcomm and other component vendors on reference designs, design reviews, and technical issue resolution.
• Support manufacturing test development,



production troubleshooting, component obsolescence, and design improvements.
• Contribute to design reviews, engineering documentation, and design guidelines, and share technical expertise with other engineers.
