Senior STA / Timing Constraints Engineer

Job Title

Senior STA / Timing Constraints Engineer

Role Summary

Work on static timing analysis (STA) and timing constraints for IP, subsystem, and full-chip designs within the physical implementation flow. Support timing signoff, constraint development, pre-route timing checks, and ECO-driven timing closure for high-frequency designs.

Experience Level

Senior-level; typically 5+ years of relevant experience in timing constraints and STA for ASIC/SoC designs.

Responsibilities

Primary responsibilities include:

• Develop multi-mode / multi-corner SDC timing constraints compatible with RTL and signoff flows.
• Ensure constraints quality using industry tools and run pre-route timing checks and QoR cleanup to prepare for STA.
• Drive timing closure for sub-chip/subsystem or full-chip, including interface timing and DRV closure.
• Generate timing ECOs using tools such as DMSA/Tweaker and lead ECO implementation to close timing gaps.
• Analyze timing reports to identify both design and constraints-related issues and implement fixes.
• Collaborate with physical design, verification, and DFT teams during signoff and handoff.
• Develop and maintain Tcl/Linux scripts to automate timing flows and EDA tool interactions.

Requirements

Must-have and preferred technical skills:

• Must-have: Strong TCL/scripting skills and experience in Linux-based EDA environments.
• Must-have: Practical experience with STA methodology, corner definitions, SDC constraints, and timing signoff (OCV/AOCV/POCV analysis).
• Must-have: Experience performing timing closure and analyzing timing reports for high-frequency blocks and subsystems.
• Preferred: Experience with Synopsys Design Compiler / PrimeTime, Spyglass, Fishtail, Tweaker, DMSA or similar EDA tools.
• Preferred: Understanding of physical design flow, ECO implementation, and DFT mode requirements for timing signoff.
• Preferred: Experience in flat and hierarchical implementation flows and working on full-chip timing closure.

Education Requirements

Bachelor's or Master's degree in Computer Engineering or Electrical Engineering.
