About the Role

Seeking a senior engineer and technical leader with deep expertise in hardware and CAD flow development to own and drive Apple's AMS (Analog/Mixed-Signal) simulation methodology. You will architect, lead, and continuously evolve the AMS simulation methodology and tooling strategy for analog, RF, interconnect, PMIC, and memory design teams. Your leadership will directly shape customer experiences through the delivery of state-of-the-art processors.

Responsibilities

  • Architect, develop, maintain, and enhance AMS (Analog/Mixed-Signal) simulation methodology and solutions for analog, RF, and mixed-signal designs.
  • Provide flows/methodologies for different tool sets across various technology nodes.
  • Collaborate closely with design teams.
  • Drive and coordinate efforts to develop and validate AMS/co-simulation flows.
  • Ensure ease of use, speed up design validation, and guarantee functional silicon.
  • Mentor engineers, influence technical direction, and lead small development teams to deliver novel and complex CAD solutions.
  • Define how design engineers interact with and leverage mixed-signal simulations and design verification workflows.
  • Lead the application of LLMs/AI agents to CAD software development, test generation, debugging, and team-wide efficiency improvements.
  • Lead small software development teams to design and deliver novel, complex CAD applications.

Requirements

  • Bachelor's degree in Computer Science, Electrical Engineering, Computer Engineering, or related field.
  • 10+ years of relevant AMS (Analog Mixed-Signal) industry experience.
  • Strong proficiency in Python, Perl, C/C++, or TCL programming.
  • Deep, hands-on experience with mixed-signal co-simulation tools and methodologies.
  • Expert-level experience with mixed-signal simulation implementation including discipline resolution, binding, IE setup, Connect Modules, AMSD blocks, wreal, TCL probes, real number modeling, UDNs, etc.
  • Proficiency with behavioral and functional circuit description languages including SystemVerilog, VerilogA, Verilog, Verilog-AMS, VHDL.
  • Strong understanding of custom IC designs and transistor description formats (SPICE, DSPF, schematics).
  • Advanced skills in object-oriented programming, data structures, algorithms, system architecture, command-line and GUI interaction, testing/coverage, and revision control.
  • Deep expertise in Virtuoso Schematic Editor, PDK content, CDF properties, hierarchy editor, SKILL code, netlisting, and Analog Design Environment (ADE).
  • Exceptional communication and presentation skills with a demonstrated ability to influence technical direction at senior and executive levels.
  • Proven track record of driving quality and productivity improvements at an organizational level.
