Senior Hardware Engineer – High-Speed Design & Validation

Key Responsibilities: Design and develop complex hardware solutions for networking and other high-performance products. Perform schematic design, component selection, hardware architecture, and design reviews. Work with high-speed interfaces including SERDES (>25G), PCIe Gen 5 and above, and associated protocols. Design and integrate low-speed interfaces such as SPI, I2C, MDIO, SMBus, and related management interfaces. Work with optical interfaces including QSFP, QSFP-DD, and OSFP. Design and validate DDR5 and SSD/NVMe PCIe-based interfaces. Develop and analyze complex power supply architectures for networking products. Use Cadence toolchain for schematic capture, PCB/CAD design, and related hardware development activities. Perform board bring-up, hardware debugging, validation, and qualification. Conduct detailed hardware failure analysis, root-cause analysis, and corrective actions. Develop and execute hardware validation and qualification plans based on functional specifications. Collaborate with firmware, software, mechanical, thermal, manufacturing, and system engineering teams. Support prototype development, design verification, manufacturing, and production issues. Document design decisions, test results, failures, root causes, and corrective actions.
