Full Chip STA Engineer
Job Description
Position: Full Chip STA Engineer
Location: San Jose, CA
Duration: Full Time Permanent
Key Responsibilities:
Own full-chip STA for full chip programs.
Develop, refine, and validate top-level SDC constraints including clocks, generated clocks, virtual clocks, I/O timing, false/multicycle paths, and hierarchical timing interfaces.
Perform timing analysis across complex setups, capturing specific corner definitions, derates, and signoff criteria.
Drive timing closure through close interaction with physical design teams across floorplanning, CTS, P&R, and ECO cycles.
Debug timing issues arising at block, subsystem, and full-chip level; guide design teams to provide RTL/PnR fixes.
Review and integrate SDC constraints from multiple IP and subsystem owners; ensure alignment with methodology.
Provide justification for timing exceptions and validate them against real design intent.
Execute timing signoff checks including SI, OCV/AOCV, uncertainty modeling, waveform compliance, IO/PHY timing, and asynchronous interface handling.
Support full-chip integration, clocking architecture reviews, and hierarchical STA closure.
Participate in timing methodology improvements and contribute to internal scripts and flows.
Required Skills & Experience:
12+ years of hands-on experience in Static Timing Analysis and SDC constraint development.
Proficiency with TCL scripting and automation of STA flows.
Solid understanding of physical design, including CTS, placement, routing, useful skew, and ECO timing strategies.
Strong debugging skills and ability to resolve critical timing issues under tapeout schedules.
Experience in advanced technology nodes (e.g., 7nm, 5nm) with signoff exposure.
