Synopsys PrimeTime STA Engineer Jobs: Browse Timing Roles
PrimeTime is the tool that signs off timing at the end of nearly every tapeout. If a chip ships, PrimeTime almost certainly cleared its setup and hold margins first. That makes it one of the few EDA platforms where deep, demonstrated proficiency reliably moves you up the candidate list.
These roles want more than a passing knowledge of the GUI. Hiring managers look for engineers who run MCMM timing analysis across the full corner set, validate SDC constraints against the real design intent, and handle crosstalk-aware SI analysis without flooding the report with false violations. ECO-guided closure is the daily work: read the violation, pick the fix, and feed the patch back to Innovus or ICC2. PrimeTime PX for power estimation is a plus that shows up more often at senior and staff levels. For the broader role category, see STA engineer jobs.
Most of the demand sits at companies that run Synopsys-primary signoff flows. Large fabless shops like Apple, Nvidia, Qualcomm, and AMD staff dedicated timing teams, and IDMs such as Intel do the same. AI accelerator startups hire PrimeTime specialists too, often because a single timing closure miss can slip a tapeout by weeks. Knowing whether a company runs a Cadence-primary, Synopsys-primary, or mixed-vendor flow before you apply helps you target the interview prep that actually matters.
Timing signoff is close enough to the layout that PrimeTime experience tends to travel with broader physical design work. In the US, timing and signoff roles commonly post in the $150K to $210K base range, with staff-level total comp running higher at large fabless companies. The salary guide for semiconductor jobs has more detail by level and region.
If you have done a full tapeout in PrimeTime, lead with that. Which blocks you closed, what QoR you recovered, how you debugged a nasty SI or variation issue: that story carries far more weight than a tool list.

FAQ
What PrimeTime analysis modes should STA engineers know
Setup and hold analysis, multi-mode multi-corner (MCMM) timing, signal integrity crosstalk analysis, AOCVM and POCV variation modeling, and ECO mode for targeted fixes. PrimeTime PX for dynamic power and PrimeTime ADV for advanced-node variation are usually expected at senior and staff levels.
How is PrimeTime used in ECO flows
PrimeTime flags violations in its analysis reports, and ECO mode generates targeted netlist fixes such as cell swaps, buffer insertions, and wire sizing without a full re-synthesis. Those ECO patches get implemented in the physical design tool, Innovus or ICC2, and timing is re-run to confirm closure.
What is the difference between AOCVM and POCV
AOCVM applies a single derating factor to model on-chip variation across clock and data paths. POCV uses a statistical distribution, which is more complex but less pessimistic. Advanced-node designs typically sign off with POCV to keep timing margins accurate without piling on extra pessimism.
