Senior Hardware Design Engineer

Tips: Provide a summary of the role, what success in the position looks like, and how this role fits into the organization overall. Role: Network Hardware Engineer Location: San Jose, CA – Onsite Start Date: Immediate Availability Background Check: MANDATORY Role Overview We are seeking an experienced Network Hardware Engineer to support the architecture, design, validation, and bring-up of next-generation high-performance routers, network switches, and 800G-class networking platforms . The ideal candidate will have strong hands‑on experience with high-speed digital hardware, SerDes, SI/PI analysis, power architecture, PCB design, and board‑level validation. Key Responsibilities Define hardware architecture for next‑generation router and network switch products. Analyze and design high‑speed interfaces, including 800G line cards and complex high‑speed SerDes interfaces . Perform requirements analysis and select key components such as Processor SoC, DDR, GPU, FPGA, network switch ASICs, PCIe switches, clocking, and power‑management devices . Drive hardware architecture, high‑level design, critical component selection, schematic capture, and design analysis. Develop PCB stack‑up requirements based on board thickness, signal speed, impedance, and power architecture requirements. Perform pre‑and post‑layout Signal Integrity (SI) analysis , including: High‑speed eye diagram analysis Overshoot/undershoot analysis Crosstalk analysis DDR batch simulation SERDES interface simulation Perform Power Integrity (PI) analysis , including voltage‑drop, current‑density, plane‑noise, and decoupling analysis. Conduct thermal analysis of high‑power/hot‑spot components and determine appropriate heatsinks, thermal pads, and other thermal solutions. Collaborate closely with software, PCB layout, mechanical, applications, and system engineering teams to resolve design issues. Lead board bring‑up, electrical validation, and signal‑quality testing . Design and validate power‑management circuits/devices and perform stress testing and board‑level functional validation. Validate hardware performance under various corner‑case and operating conditions. Troubleshoot board‑level hardware issues and drive corrective actions through product development and validation. Mandatory Skills Strong hands‑on experience with board bring‑up and electrical validation . Experience performing signal‑quality testing and validation of high‑speed circuits. Experience designing and validating power‑management devices/circuits . Hands‑on experience with stress testing and board‑level functional testing . Strong understanding of high‑speed digital hardware, PCB design, SI/PI, and hardware debugging. Preferred Technical Background Router, switch, networking, server, telecom, or high‑performance computing hardware. High‑speed interfaces such as 800G Ethernet, SerDes, PCIe, DDR, Ethernet PHYs, and high‑speed clocks . Signal Integrity / Power Integrity tools and simulation methodologies. Hardware architecture and schematic design. PCB stack‑up, impedance control, high‑speed routing, and post‑layout analysis. Thermal and power analysis. Experience with complex networking ASICs, FPGAs, SoCs, and PCIe switches. Ideal Candidate The strongest candidate would typically have 8–15+ years of hardware engineering experience with significant hands‑on work in networking equipment, routers/switches, high‑speed boards, or telecom/server platforms . Candidates who have progressed from Hardware Design Engineer → Senior/Lead Hardware Engineer → Hardware Architect are particularly relevant. #J-18808-Ljbffr
