Job description

Santa Clara, California, United States Hardware

Do you want to directly impact the performance of every iPhone, iPad, and Mac? You'll push the boundaries of physical synthesis for Apple's cutting-edge processors, solving problems that determine whether our next-generation CPUs, GPUs, and NPUs can deliver breakthrough performance while maintaining industry-leading power efficiency.

Description

You'll own the synthesis challenges that matter most to Apple Silicon. You will apply your hands-on skills in developing, improving and supporting the implementation flow from RTL through GDS signoff. You will be directly responsible to improve physical synthesis techniques through innovative scripts, flows and automation.As the synthesis and flow expert, you'll partner closely with design teams to define what works best for their specific challenges. You'll develop the methodologies, tools, and optimized flows that enable design teams to achieve breakthrough PPA results. You'll push beyond conventional synthesis limits - developing innovative techniques and proving their effectiveness by running full validation flows from RTL through place-and-route and timing signoff to show actual PPA improvements. Your optimizations will directly translate to faster, more efficient Apple devices.You'll work directly with EDA vendors to shape tool roadmaps, build custom solutions for problems that push beyond industry standards, and see your work ship in millions of devices.
