About the role

Senior engineer and technical leader responsible for owning and evolving Apple's AMS (Analog/Mixed-Signal) simulation methodology and tooling, across analog, RF, interconnect, PMIC, and memory design teams. Leads architecture, development, and adoption of CAD automation and mixed-signal verification workflows, mentors engineers, and drives cross-functional initiatives to deliver validated IP in silicon.

Responsibilities

  • Own and define the direction and roadmap for a state-of-the-art mixed-signal simulation methodology across multiple technology nodes and diverse circuit/IC types
  • Serve as the primary technical authority for custom/transistor-level circuit design teams, taking end-to-end accountability for functional behavior, performance verification, and analog/digital interface integrity
  • Lead the investigation, architecture, and org-wide adoption of novel CAD automations — driving impact that scales beyond individual projects
  • Own and manage the strategic relationship with third-party EDA tool vendors — defining requirements, driving tool improvements, and holding vendors accountable to Apple's quality and performance standards
  • Lead resolution of the most critical and ambiguous technical challenges, leveraging deep expertise, creative problem-solving, and cross-functional influence
  • Define and champion the strategy for bridging the analog and digital domains, establishing best practices adopted across design teams
  • Proactively own risk identification and systemic mitigation across design quality — architecting durable solutions that close structural gaps in simulation and modeling methodology
  • Mentor and technically guide junior and mid-level engineers, elevating team capability and fostering a culture of engineering excellence
  • Lead small software development teams in the design and delivery of novel, complex CAD applications

Qualifications

  • 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 industry-standard AMS tools including Cadence (Xcelium, Verisium/Indago, SimVision, AMS Designer), Synopsys (VCS, Verdi), or Siemens (Questa, Symphony)
  • Deep knowledge of analog simulation tools such as Cadence Spectre, Synopsys PrimeSim/HSPICE/Finesim, or Siemens AFS
  • Proven track record of architecting and delivering solutions to complex simulation accuracy, speed, and capacity challenges at scale
  • 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
  • Demonstrated experience leading the application of LLMs/AI agents to CAD software development, test generation, debugging, and team-wide efficiency improvements
  • 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
  • Demonstrated experience leading small software development teams to design and deliver novel, complex CAD applications
