## Description

We, signal integrity team under NHE, are a close-knit, creative, and multi-skilled team where each person is unique, but we bring our talents together to work on the design and development of next-generation Security Firewall products and Campus and Date Center Routing systems. As a Signal Integrity Engineer, you will contribute to PCB board design, simulation, and validation of high speed Serdes, DDR/LPDDR and power delivery network, collaborating with experienced engineers and multi-functional teams.
Your Impact

 * Assist in the design and analysis of high-speed digital and analog systems from concept through to production.
 * Perform signal integrity simulations using industry-standard tools.
 * Model and analyze power delivery networks to ensure signal integrity and system reliability in next-generation hardware.
 * Optimize pre- and post-route signal integrity analysis of PCBs.
 * Support prototype function bring-up, and system-level validation and troubleshooting.
 * Collaborate with hardware, layout, and validation teams to resolve technical issues.
 * Contribute to documentation, data analysis, and correlation of simulation and lab measurements.
