Senior Staff STA Engineer

Senior/Staff STA (Static Timing Analysis) Engineer 

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. 

What youll do 

• 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 :

What were looking for 

• 412 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.
