201 jobs for "Signal Integrity Engineer"

At Apple, we push the boundaries of what's possible and nowhere is that more evident than in the infrastructure that powers our most ambitious technologies. The Data Center Hardware Engineering Team designs and delivers the high-performance compute solutions that underpin Apple's services and products at scale. From custom silicon to full-system integration, our work ensures that Apple's global infrastructure is fast, efficient, and built to last. Every system we ship reflects our relentless commitment to engineering excellence and our belief that great hardware is the foundation of great experiences.

The Hardware System Integration team is central to this mission, owning the design and realization of customized compute platforms from concept through mass production. We're looking for a Hardware System Integration Engineer who thrives in a highly collaborative environment, enjoys working across disciplines, and is energized by the challenge of bringing cutting-edge server hardware to life.

Description

As a Hardware System Integration Engineer, you will contribute to the end-to-end hardware engineering lifecycle for high-performance server compute designs from specification and schematic capture through board bring-up, validation, and factory build support. Working alongside senior engineers on the team, you will grow into board-level design ownership while partnering closely with mechanical, power, software, firmware, silicon, manufacturing, and reliability teams to ensure design requirements are met with precision and at scale. This role demands both technical depth and strong communication skills to drive alignment across a broad set of stakeholders.","responsibilities":"Hardware system design and schematic capture for server main logic boards and companion boards, including board layout guidance and design constraint management

Perform signal integrity simulation, board bring-up, and hands-on debug from the system level down to the component or circuit level

Develop and maintain functional specifications, validation plans and 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, manufacturing, and reliability teams to balance design tradeoffs and meet program requirements
