Timing Constraints Engineer

Responsibilities

• Develop and validate timing constraints (SDC) for functional and test/DFT modes (scan shift/capture, at-speed/test clocks, JTAG/MBIST as applicable).
• Own constraints correctness and completeness at SoC level and block/subsystem level, ensuring clean constraint handoff and consistent intent across modes.
• Drive timing analysis support and closure activities by partnering with STA/signoff owners to resolve constraint-related violations
• Create, review, and maintain timing exceptions (false paths, multicycle paths, case analysis, clock groups, disable timing) with clear rationale and traceability.
• Enable IP integration timing signoff readiness by ensuring reusable, clean, and modular constraint collateral for integrated blocks.
  
  

Required Skills and Experience

• 2–6 years of experience in Physical Implementation and Signoff methodologies, with strong exposure to timing constraints for functional + test modes.
• Proven experience supporting timing closure at SoC and block levels (constraints ownership, violation triage, exception strategy, signoff readiness).
• Solid understanding of IP integration flows and timing signoff expectations (constraint packaging, mode consistency, clocking intent, exceptions).
• Experience working on advanced technology nodes, preferably sub-7nm, with awareness of signoff requirements.
• Strong data analysis and presentation skills (summaries, dashboards, signoff readiness reporting).
• Well versed in Tcl and at least one scripting language (Python/Perl) for automation and data processing.
• Demonstrated experience collaborating across silicon engineering groups and working with EDA vendors to debug tool/flow issues and close gaps.
• Strong communication and problem-solving skills; ability to drive issues to closure across teams.
