Job Description

We are seeking a highly skilled Analog Mixed-Signal SerDes 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 high-performance analog and mixed-signal circuits used in SerDes PHY.

Key Responsibilities:

  • Design and develop high-speed analog and mixed-signal circuits, including evaluation of different circuit topologies for specific product requirements.
  • Collaborate with cross-functional teams to create block-level specifications and execute on transistor-level implementation and behavioral modeling.
  • Drive mask design to implement layout views of designs.
  • Work closely with SOC teams to deliver IP views and ensure they meet quality standards.

Requirements:

  • Deep knowledge of analog mixed-signal design with experience in high-speed serial links.
  • Solid understanding and experience of designing analog mixed-signal circuit blocks, including bandgap, biasing circuits, LDO regulators, amplifiers, comparators, switched-cap circuits, ADCs, DACs, oscillators, and filters.
  • Proven understanding of analog mixed-signal concepts, including mismatch mitigation, linearity, stability, low-power, and low-noise techniques.
  • Good grasp and understanding of digitally assisted analog design concepts, including background calibrations and LMS-based adaptive loops.
  • Experience with high-speed digital circuits, including serializers, deserializers, counters, dividers, and other related circuits.
  • Knowledge of Tx/Rx equalization techniques and circuits, including CTLE, DFE, and de-emphasis, for 20+ Gbps NRZ and PAM applications.
  • Knowledge of CDR architectures and implementations.
  • Knowledge of lab equipment and testing.
  • Experience in analog mixed-signal circuit modeling and performance evaluation, including SystemVerilog, Matlab, Python, and VerilogAMS.
  • Hands-on experience in advanced CMOS technologies and 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, including Nanotime and Primetime.
  • Experience in lab testing of high-speed serial I/O, debug, and data analysis techniques.
  • Knowledge of common high-speed SerDes protocols, including PCIe, USB, DP, and MPHY.
  • Skills in scripting and automation to enhance efficiency.

What We Offer:

  • Competitive base pay, ranging from $143,100 to $264,200, depending on skills, qualifications, experience, and performance.
  • Opportunity to become an Apple shareholder through participation in Apple's discretionary employee stock programs.
  • Comprehensive medical and dental coverage, retirement benefits, and a range of discounted products and free services.
  • Reimbursement for certain educational expenses related to advancing your career at Apple.
  • Discretionary bonuses or commission payments, as well as other benefits.

Apple is an Equal Opportunity Employer:
