About the role

Engineer to develop, maintain, and enhance AMS (Analog/Mixed-Signal) simulation methodology and tools for analog, RF, interconnect, PMIC, and memory design teams; contribute to CAD automations, co-simulation flows, and interfaces with design workflows to enable efficient mixed-signal verification and IP delivery.

Responsibilities

  • Contribute to the direction and development of a state-of-the-art mixed-signal simulation methodology across many different technology nodes and circuit and IC types.
  • Work directly with world-class custom/transistor-level circuit designers to ensure the expected functional behavior, performance, and interfaces with digital/RTL blocks.
  • Investigate challenges, propose solutions, complete execution, and drive adoption of novel CAD automations.
  • Collaborate with third-party EDA tool vendors to ensure their tools meet our high quality standards and extreme performance needs.
  • Solve critical issues using creativity, knowledge, intuition, and teamwork
  • Support efforts to bridge the gap between analog and digital domains
  • Identify risks to design quality and contribute to solutions that close gaps in design execution using simulation and modeling

Qualifications

  • Bachelor's degree in Computer Science, Electrical Engineering, Computer Engineering, or related field +0 years of experience
  • Experience in Python, Perl, 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
