About the Role

We are seeking an engineer with a passion for hardware and strong CAD flow development and collaboration skills to develop, maintain, and enhance AMS simulation methodology and tools for our analog, RF, interconnect, PMIC, and memory design teams. You will enable design engineers to efficiently drive and interact with their mixed-signal simulations and design verification workflows, delivering validated IP in cutting-edge silicon. Your contributions will directly impact the experiences of millions of Apple customers by delivering state-of-the-art processors across the diverse range of Apple products.

Responsibilities

  • Architect, develop, maintain and enhance AMS simulation methodology and solutions for analog, RF, and mixed-signal designs.
  • Work with different technology nodes and provide flows/methodologies for different tool sets.
  • Collaborate closely with design teams.
  • Drive and coordinate efforts to develop and validate AMS/co-simulation flows, providing ease of use, speeding up design validation, and ensuring functional silicon.

Requirements

  • Bachelor's degree in Computer Science, Electrical Engineering, Computer Engineering, or related field.
  • 3+ years of relevant AMS industry experience.
  • Experience in Python, Perl, C/C++, or TCL programming.
  • Experience using mixed-signal co-simulation tools.
  • Experience with industry-standard AMS tools including Cadence (Xcelium, Verisium/Indago, SimVision, AMS Designer), Synopsys (VCS, Verdi), or Siemens (Questa, Symphony).
  • Familiarity with analog simulation tools such as Cadence Spectre, Synopsys PrimeSim/HSPICE/Finesim, or Siemens AFS.
  • Ability to identify and address simulation accuracy, speed, and capacity issues.
  • Experience with mixed-signal simulation implementation including discipline resolution, binding, IE setup, Connect Modules, AMSD blocks, wreal, TCL probes, real number modeling, UDNs, etc.
  • Understanding of behavioral and functional circuit description languages including SystemVerilog, VerilogA, Verilog, Verilog-AMS, VHDL.
  • Familiarity with applying LLMs/AI agents to CAD software development, test generation, and debugging.
  • Understanding of custom IC designs and transistor description formats (SPICE, DSPF, schematics).
  • Fundamentals in object-oriented programming, data structures, algorithms, system architecture, command-line and GUI interaction, testing/coverage, and revision control.
  • Familiarity with Virtuoso Schematic Editor, PDK content, CDF properties, hierarchy editor, SKILL code, netlisting, and Analog Design Environment (ADE).
  • Strong communication and presentation skills.
  • Demonstrated commitment to quality and productivity.
