Sr. Staff Physical Design Timing Engineer (STA)

About this role

Responsibilities

• Drive the STA sign-off for our flagship Silicon photonics chips at various technology nodes.
• Analyze fab guidelines and work with the methodology team to incorporate sign off corners, margins, and derates into timing analysis flows and methodologies.
• Collaborate with the architecture, RTL, and DFT teams to analyze the timing complexities and develop consolidated timing modes and constraints for synthesis, along with PnR and chip timing sign-off flows.
• Analyze and understand the tradeoffs between power/performance and area goals to drive them into overall chip implementation flows.
• Run full-chip STA and accurately project the timing summary across scenarios.
• Leverage Tempus/PrimeTime to automate timing ECO generation for effective closure and support physical design implementation.
• Document best practices and lessons learned to drive continuous improvements in future projects.
• Qualifications:
• Bachelor’s degree in Electrical Engineering or Computer engineering
• 12 years of Physical Design experience, with a minimum of 5 years hands-on experience in ASIC STA and timing constraints development, timing closure with Cadence or Synopsys tools
• Experience in driving timing closure by effectively managing on-chip variation derates, optimizing multi-mode multi-corner constraints, and implementing robust clock tree building strategies
• Well versed with scripting languages like TCL and Python, PERL, or Shell
• Strong problem solving skills with attention to every technical aspect
• Be a strong team player with clear and precise communication skills
• Preferred Qualifications:
• Master’s degree in Electrical Engineering or Computer engineering
• A minimum of 8 years of hands-on experience in ASIC STA and timing constraints development, timing closure with Cadence or Synopsys tools
• We offer competitive compensation. The base salary range for this role determined based on location, experience, educational background, and market data.
