Santa Clara Valley (Cupertino), California, United States


Role Number:200316058
As part of our Silicon Technologies group, you’ll help design and manufacture our next-generation, high-performance, power-efficient processor, system-on-chip (SoC). You’ll ensure Apple products and services can seamlessly and efficiently handle the tasks that make them beloved by millions! Joining this group means you’ll be responsible for crafting and building the technology that fuels Apple’s devices. Together, you and your team will enable our customers to do all the things they love with their devices. The Signoff Engineer ensures that all critical, necessary, and appropriate verification and analysis work has been performed on a design before tapeout. In this high-visibility position you will be responsible for the definition, development, and implementation of signoff requirements for PNR construction flows, and analysis for STA, Noise, and Clocks of high-volume state-of-the-art SOC, working with other teams in the organization to verify that the EDA flows and tools are set up and run correctly during the project, and all signoff criteria are met at the end of the project. This role also requires direct interaction with technology, CAD, and design groups to provide frontline support for enablement, enhancement, and debug requests.
