Job Title: SerDes Circuit Design Engineer

We are seeking an experienced SerDes Circuit Design Engineer to join our team at Apple. As a key member of our high-speed SerDes team, you will be responsible for designing and developing next-generation high-performance wireline transceivers.

About the Role

In this role, you will work closely with cross-functional Analog Mixed-Signal design teams to create state-of-the-art IPs for Apple's world-leading system-on-chip (SOC). You will be challenged to make best-in-class designs that surprise and delight Apple customers.

Key Responsibilities
  • Design and develop high-performance and high-speed AMS circuits used in SerDes PHY
  • Evaluate different circuit topologies for specific product requirements
  • Work with multi-functional teams to create and drive block-level specifications, mixed-signal implementations, and behavioral modeling
  • Deliver IP views and ensure they meet quality standards
  • Interact with peers and management to communicate progress, discuss new ideas, and drive new implementations/concepts
Requirements
  • Deep understanding of AMS design with experience in high-speed serial links
  • Solid understanding of designing AMS circuit blocks, including Bandgap, biasing circuits, LDO regulators, amplifiers, comparators, switched-cap circuits, ADCs, DACs, Oscillators, Filters
  • Understanding of analog mixed-signal concepts like mismatch mitigation, linearity, stability, low-power, and low-noise techniques
  • Deep understanding and experience with digitally assisted analog design concepts (e.g., background calibrations, LMS-based adaptive loops)
  • Proven experience working on system and architecture teams to drive block-level and IP requirements
  • Proven track record working with large teams and guiding junior engineers
  • Experience with high-speed digital circuits (e.g., serializer, deserializer, counters, dividers, etc.) with solid understanding of digital design concepts
  • Experience and proven understanding of Tx/Rx equalization techniques and circuits (e.g., CTLE, DFE, de-emphasis) for 20+ Gbps NRZ and PAM applications
  • Experience with EQ adaptation methods and circuit interactions to improve PPA
  • Solid understanding of CDR architectures and implementations
  • Experience in Analog Mixed-Signal circuit modeling and performance evaluation (e.g., SystemVerilog, Matlab, Python, VerilogAMS)
  • Hands-on experience to drive lab testing, debug, and data analysis
  • Hands-on experience in advanced CMOS technologies, design with FinFet technology
  • Hands-on experience with AMS IC development from definition to high-volume production, including layout supervision, bench evaluation, correlation, and characterization
Preferred Qualifications
  • Concepts of timing closure and related industry tools (e.g., Nanotime, Primetime)
  • Concepts of IP delivery and quality checks
  • Knowledge of common high-speed SerDes protocols (e.g., PCIe, USB, DP, MPHY)
  • Skills in scripting and automation to improve efficiency
Education & Experience

BSEE with 10+ years of proven experience. Apple is an Equal Opportunity Employer that is committed to inclusion and diversity.
