Principal Physical Design Engineer, STA
$143,800 - $230,000 USD yearly
Originally posted 31 October 2026 by the employer.
About the role
As a Principal Physical Design Engineer specializing in Static Timing Analysis (STA) within the ASIC Products Division (APD), you will ensure high-performance ASICs meet timing requirements across operating conditions. The team focuses on full-chip physical implementation and timing closure for custom ASICs across advanced foundry nodes including N7, N5, N3, and N2.
What you'll do
- Own full-chip timing sign-off and final timing closure across PVT corners, authoring and maintaining SDC for functional and test modes.
- Deploy AI/ML automation within STA flows to minimize execution runtime, improve infrastructure efficiency, and implement ML-based corner reduction while maintaining physical coverage.
- Triage violations and isolate root causes using automated workflows and data mining to eliminate timing and design marginalities across clock networks and multi-die boundaries.
- Leverage advanced OCV, SI, and IR-drop concepts to drive timing ECOs and collaborate with RTL, Physical Design, and DFT teams to optimize PPA.
What you'll need
- Bachelor’s degree in Electrical or Computer Engineering.
- 12+ years of hands-on ASIC STA and timing closure experience.
- Expert proficiency in sign-off tools such as PrimeTime or Tempus.
- Expertise in advanced multi-mode multi-corner (MMMC) scenarios and on-chip variation (OCV) management.
- Strong scripting skills in Tcl, Python, Perl, and Shell.
- Experience utilizing AI plugins and data-mining scripts for runtime reduction and reporting.
