Senior/ Staff STA Engineer

Job Title

Senior/ Staff STA Engineer

Role Summary

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 various teams to debug violations and drive ECO-based optimizations through tapeout.

Experience Level

Mid-level; 4–12 years of experience in Static Timing Analysis (STA) and timing closure.

Responsibilities

Key responsibilities include:

• 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.
• Collaborate 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.

Requirements

The desired qualifications are:

• Strong understanding of CMOS fundamentals, timing concepts, and semiconductor design flow.
• Hands-on experience with setup/hold analysis, and various timing violations.
• Experience with timing constraints development and debugging.
• Familiarity with timing closure techniques and ECO methodologies.
• Knowledge of SDC and timing exceptions
• 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.

Education Requirements

Not specified.
