  • Build automation frameworks using Python and Tcl to support synthesis through signoff.
  • Perform hands-on Physical Design and PNR, including floorplanning, placement, CTS, routing, and timing closure.
  • Develop and optimize EDA tool flows for timing analysis, extraction, EM/IR, and physical verification.
  • Support block-level implementation from synthesis through GDSII signoff.
  • Improve design quality, automation, and flow efficiency.
  • Collaborate with design, verification, and engineering teams to support ASIC development and tapeout.

Required qualifications

  • Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field
  • 5+ years of experience in ASIC Physical Design, CAD methodology, or design automation
  • Strong understanding of physical design implementation and RTL-to-GDSII methodologies
  • Experience developing or maintaining Physical Design CAD flows
  • Hands-on experience with PNR, timing closure, and physical design signoff
  • Proficiency in Python and/or Tcl scripting
  • Experience with Cadence and/or Synopsys physical design tools
  • Experience with advanced semiconductor process nodes (7nm or below)

Nice to have

  • Master's degree
  • Experience with 3nm or more advanced process technologies
  • Experience building automated CAD flows from synthesis through signoff
  • Familiarity with Cadence Innovus, Tempus, Genus, Synopsys ICC2, Fusion Compiler, and PrimeTime
