Senior Engineer - STA

Job Title

Senior Engineer - STA

Role Summary

Work on static timing analysis (STA) and timing signoff for SoC IP at the block/subsystem level. The role sits within the Design Engineering organization and interfaces with Physical Design, RTL/Design, DFT, and constraint teams to achieve timing closure across modes and corners.

Experience Level

Senior - the posting specifies 2–4 years of relevant experience.

Responsibilities

Primary duties focus on timing analysis, constraint development, and closure activities.

• Develop and validate timing constraints for functional and test modes.
• Perform timing analysis and drive timing closure at block and subsystem levels.
• Analyze setup and hold violations; coordinate fixes with Physical Design and RTL/Design teams.
• Support timing ECO generation, implementation, and validation.
• Generate and review timing reports across modes and corners; debug timing/constraint issues.
• Support timing signoff activities and handoffs.

Requirements

Must-have technical skills and experience.

• Solid understanding of STA fundamentals: setup/hold, clocking, timing exceptions, and constraints.
• Hands-on experience with STA tools such as PrimeTime or Tempus.
• Basic understanding of Physical Design flow: placement, CTS, routing, and timing closure.
• Familiarity with timing ECO techniques (cell sizing, buffering, Vt swaps) and MMMC timing analysis.
• Scripting skills in TCL, Perl, or Python for automation and data analysis.
• Ability to analyze timing data, debug issues, and collaborate across PD, RTL/Design, DFT, and constraint teams.
• Good communication and problem-solving skills.
• 2–4 years of experience in Physical Implementation, STA, or Timing Signoff.
• Nice-to-have: knowledge of advanced technology nodes.

Education Requirements

Not specified.
