About the role

Silicon design role within Apple’s Digital group focused on designing state-of-the-art ASICs and custom digital megacells (e.g., SRAM memories, on-chip sensors, ML accelerators data path) for high performance/low power SOCs. Collaborates across groups to turn innovative ideas into real silicon, with opportunities to drive methodologies and bring new ideas to production.

Responsibilities

  • Develop custom circuits to improve chip power efficiency.
  • Work with power team, PD and architects to define specifications and requirements
  • Perform design, analysis, modeling/simulation, circuit level specifications, schematic capture, spice simulation / margin verification across PVT, statistical design, functional verification and silicon bring up.
  • Work closely with layout team to complete the design and oversee the layout quality.
  • Develop / drive circuit methodology to achieve the highest design quality metrics.

Qualifications

  • BS and a minimum of 3 years of relevant industry experience
  • We are looking for applicants with design experience in advanced technology nodes.
  • Experience in design of low voltages / low power custom circuits.
  • Experience in one or multiple of the following areas is highly desirable: Machine learning accelerators, SRAM circuits, non-volatile memories, weak / moderate inversion circuits, ultra-low power amplifiers, DC/DC converters, digital on-chip sensors, high speed clocking, time to digital converters (TDCs).
  • Deep understanding of deep submicron device physics, leakage mechanisms, technology interactions with device behavior.
  • Solid understanding of device matching, device noise sources (1/f, thermal), extrinsic noise sources (supply, jitter), and their impact on high precision circuit.
  • Ability to conduct experiments during silicon debug, gathering and analyzing data; and utilize scripting to support efficient handling of ATE data.
  • Familiar with mixed signal verification and behavioral models for mixed signal blocks.
  • Proficiency in scripting languages (Python /Perl or others) and CAD automation tools.
  • Knowledge of industry standard circuit and design tools.
