At Apple, we work every single day to craft products that enrich people’s lives. Do you love working on challenges that no one has solved yet? Do you like changing the game? We have an opportunity for a forward-thinking and unusually hardworking IC Designer. As a member of our dynamic group, you will have the rare and rewarding opportunity to craft upcoming products that will delight and encourage millions of Apple’s customers every single day.

Description
In this role, you will work on the development of high-performance and high-speed AMS circuits used in SerDes PHY, including evaluation of different circuit topologies for specific product requirements (e.g., Rx, CDR, Tx, bias generator, high-speed clock generation and low-jitter distribution, phase interpolator, DLL, VCO) with best in class power, performance, and area (PPA).

You will work with cross-functional teams (e.g., architecture, SIPI, packaging, board design, DFT, ESD) to create block-level specifications and execute on transistor-level implementation and behavioral modelling. You will drive mask design to implement layout view of designs. You will closely work with SOC teams to deliver IP views and make sure they meet the quality standards. While developing these sophisticated IPs, on regular basis you will interact with your peers/management to communicate progress and discuss new ideas making it a lively and interactive work environment.

Preferred Qualifications
PhD/master’s degree in Electric Engineering or relevant experience
