About this role
The STA Engineer is responsible for ensuring robust timing closure and signoff readiness for block- and full-chip designs across all modes and corners. This role owns timing constraint development and validation, performs detailed setup/hold and variation-aware analysis, and partners closely with Synthesis, CTS, Physical Design, and Design teams to debug violations and drive ECO-based optimizations through tapeout.
Responsibilities:
- Perform full-chip and block-level Static Timing Analysis (STA) across all modes and corners.
- Analyze and debug setup, hold, recovery, removal, clock gating, and signal integrity-related timing violations.
- Work closely with Physical Design, Synthesis, CTS, and Design teams to achieve timing closure.
- Develop and maintain timing constraints including SDC creation, validation, and signoff readiness.
- Drive timing closure through ECO implementation and timing optimization.
- Analyze timing impact due to process, voltage, and temperature variations.
- Support timing signoff for pre-layout and post-layout stages.
- Perform cross-functional reviews for timing convergence and provide recommendations.
- Generate timing reports and communicate closure status to project stakeholders. Qualifications
- 7-10 years of experience in Static Timing Analysis (STA) and timing closure for block and/or full-chip designs.
- Strong understanding of CMOS fundamentals, timing concepts, and semiconductor design flow.
- Hands-on experience in setup/hold analysis, path-based analysis, OCV/AOCV/POCV, derates, and MMMC concepts.
- Good understanding of clock tree, clock uncertainty, latency, skew, and jitter.
- Experience in timing constraints development and debugging.
- Strong knowledge of SDC, timing exceptions, false paths, multicycle paths, and case analysis.
- Familiarity with timing closure techniques and ECO methodologies.
- Hands-on experience with industry-standard STA tools such as Synopsys PrimeTime or Cadence Tempus.
- Good scripting skills in Tcl, Perl, or Python.
- Ability to analyze and resolve timing violations independently.
Nice to have
- Exposure to low-power timing analysis and UPF/CPF-aware STA.
- Familiarity with SI-aware timing, Crosstalk analysis, and IR-drop-aware timing closure.
- Knowledge of advanced technology nodes and variation-aware signoff methodologies.
- Exposure to automation and flow development.
- Experience in cross-functional collaboration with PD, RTL, and Signoff teams.
