Preferred Qualifications

High-speed PCB design experience with 10+ layer boards, including PCB material selection and stackup definition Proficiency with schematic entry and high-speed PCB layout constraint management using Cadence tools or equivalent Hands-on PCIe, 100-GbE, USB3/USB4, or similar high-speed serial protocol experience, including compliance testing and protocol analyzer debug Familiarity with computer architecture concepts and hardware design tradeoffs Experience developing automation or data manipulation scripts Master's degree in Electrical Engineering or Computer Engineering 7+ years of relevant industry work experience in hardware or systems engineering

Description

As a Hardware System Integration Engineer, you will own the end-to-end hardware engineering lifecycle for high-performance compute designs — from initial specification and schematic capture through board bring-up, validation, and factory build support. You will serve as a cross-functional partner to mechanical, power, software, firmware, silicon, and reliability teams, ensuring design requirements are met with precision and at scale. This role demands both technical expertise and strong communication skills to drive alignment across a broad set of stakeholders.

Responsibilities

Hardware system design and schematic capture for high-performance compute platforms, including board layout guidance and design constraint management Perform signal integrity simulation, board bring-up, and hands-on debug from system-level down to the transistor level Develop and maintain functional specifications, validation procedures, and integration documentation for complex system designs Execute validation of high-speed digital interfaces (PCIe, Ethernet, USB, DDR, and others) including compliance testing and protocol analysis Partner cross-functionally with mechanical, firmware, software, silicon, and reliability teams to balance design tradeoffs and meet program requirements Support factory builds and sustaining engineering activities through mass production Drive issues to root cause through systematic debugging using EE lab equipment (oscilloscope, logic analyzer, spectrum analyzer, DMM)
