Senior High-Speed I/O Engineer

Apple's products touch hundreds of millions of people - and the interfaces that connect them to the world depend on getting every signal right. The Hardware Test Engineering group is the team that makes sure they do. As a Senior High-Speed I/O Engineer, you'll own the design, development, and deployment of metrology and test instrumentation systems for Apple's most advanced hardware, spanning the full breadth of Apple's product portfolio. From the earliest NPI milestones through mass production, your work will directly shape the quality and reliability of products used by people everywhere.

In this role, you will develop and deploy automated instrumentation systems that validate the electrical function and performance of Apple’s high-speed I/O technologies across the entire product lifecycle. You'll partner deeply with System EE, Signal Integrity, Firmware, Software, Silicon Engineering, and Operations to define test strategies, drive instrumentation architecture, analyze complex system behavior, and improve engineering workflows through automation and AI-assisted analytics.

You'll bring the communication skills, analytical rigor, and cross-functional instincts to make those partnerships count. This position requires strong technical depth in high-speed electrical systems, software development, system debugging, and cross-functional leadership to solve challenging engineering problems at scale.
