We have an immediate need for an expert Physical Design Engineer to drive a high-speed design across the finish line. You will be working on a 1GHz AES hard macro targeted for the GlobalFoundries 12LP (12nm FinFET) process node. The design is nearly complete; your primary objective upon joining will be the final cleanup of 7 remaining DRC/ERC errors, completing fill insertion, and executing the final Calibre signoff checks for tape-out.
Core Technical Environment & Ongoing Responsibilities: Beyond this immediate milestone, you will take ownership of the RTL-to-GDSII flow for our next-generation SoCs, pushing the limits of Power, Performance, and Area (PPA).
  • Implementation: Execute block-level and top-level physical design (floorplanning, CTS, routing) using the Synopsys Fusion Design Platform (Fusion Compiler).
  • Timing & Signoff: Drive STA, parasitic extraction, and timing closure across multiple corners using PrimeTime and StarRC.
  • FinFET Optimization: Address 12nm FinFET challenges including advanced routing rules, EM/IR-drop analysis (Ansys RedHawk), and complex SDC constraint management.
  • Verification: Perform DRC, LVS, and antenna checks using Calibre and Synopsys IC Validator (ICV).
  • Automation: Maintain robust Tcl, Python, or Perl scripts to automate workflows.
Qualifications:
  • 10+ years of industry experience in ASIC physical design with successful tape-outs on advanced FinFET nodes (14nm/12nm/7nm).
  • Deep expertise in rapid DRC/LVS/ERC closure and final tape-out procedures.
  • Hands-on mastery of Synopsys Fusion Compiler (or ICC2) and PrimeTime.
  • Strong scripting skills (Tcl, Python, Bash).
  • Preferred: Direct experience with the GlobalFoundries 12LP/12LP+ node and Mentor Calibre.

The anticipated annual base salary for this position is between $150,000 to $165,000, which also includes a comprehensive benefits package.

Full-Time Benefits:
• 15 days of PTO per calendar year
• 10 paid Holidays per calendar year
• Comprehensive Medical Benefits: Company covers 80% of premiums for Employee and Dependents
