Job Summary

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 visionary and especially talented SerDes Circuit Designer. As a member of our dynamic group, you will have the rare and rewarding opportunity to craft upcoming products that will delight and inspire millions of Apple's customers every single day. Apple Silicon Engineering is seeking qualified SERDES designers to work on the next generation SERDES PHYs for Apple's world-leading systems-on-chip (SOCs). You will be part of a growing analog/mixed-signal team involved in design and productization on leading-edge CMOS process technology nodes.

Key Qualifications

The ideal candidate should have experience in high-speed serial links with expertise in the following: Very knowledgeable about high-speed SerDes protocols (e.g., PCIe, USB, SATA, etc.). Strong knowledge of analog CMOS designs and topologies.

Experience with Tx/Rx equalization techniques and circuits. Experience with high speed digital circuit (e.g., serializer, deserializer, counters, dividers, etc.) design, analysis and verification (e.g., STA, formal verification). Experience in analyzing link jitter budget for high-speed serial links and creating block level requirements. Knowledge of different CDR architectures.

Experience in lab testing of high-speed serial links and defining equipment needs. Experience in the following areas is helpful: Able to think outside of the box and come up with creative solutions.

Static timing analysis tools (e.g., Nanotime, Primetime, etc.). Modeling of CDR and adaptive loops (using C, Matlab or Python, etc.). Able to create VerilogA/AMS behavioral models. Knowledge of ESD requirements.


IN THIS ROLE, THE KEY RESPONSIBILITIES ARE THE FOLLOWING:Ownership of analog and digital circuits used in SerDes PHY, including evaluation of different circuit topologies for specific product requirements (e.g., Rx, CDR, Tx, bias generator, clock generation and distribution, etc.). You will interact with cross-functional teams to define requirements/specs (e.g., modeling, package, board, DFT, ESD, etc.). Create block-level specifications based on link-budget, behavioral modeling, and transistor-level feasibility. Work closely with mask design to implement layout view of designs.

Generation/QA of various IP Kit views/files for release to IP consumers. Defining production/bench-level testplans. Hold design reviews of blocks with peers/management to show design meets spec targets and requirements.


The minimum requirements for this role are an MSEE plus 7 years' experience or PhD with 5 years relevant experience.
