Staff Engineer - STA

Job Title

Staff Engineer - STA

Role Summary

Lead timing signoff (STA) activities for an SoC or subsystem. Responsible for writing and validating timing constraints, driving signoff through tapeout, and coordinating with frontend, DFT and IP teams. Uses AI tools in STA workflows and contributes to physical-design strategy across technology nodes.

Experience Level

Senior (Staff-level). No explicit years of experience provided in the source.

Responsibilities

Key responsibilities include:

• Lead complete STA timing signoff for subsystem or full-chip through tapeout.
• Develop, refine and validate timing constraints (SDC/constraints) throughout the SOC design cycle.
• Generate and validate SDF and ensure correct timing annotation and correlation.
• Collaborate with Frontend, DFT and IP teams to ensure correct constraints and timing closure.
• Apply AI techniques and tools to improve STA processes and productivity.
• Support signal-integrity (SI) closure and interact with placement, CTS and routing teams.
• Analyze physical-design issues and help define best physical-design strategies per node.

Requirements

Must-have technical skills and capabilities:

• Proven experience leading STA/signoff function for subsystem or SoC.
• Hands-on experience writing and validating timing constraints and SDF generation/validation.
• Knowledge of SI closure practices.
• Familiarity with physical-design flows, including placement, CTS and routing.
• Exposure to advanced process nodes (examples cited: 16nm and 5nm).
• Experience collaborating with Frontend, DFT and IP teams to achieve timing closure.
• Experience using AI in STA activities or willingness to adopt AI-based methods.

Education Requirements

Not specified.
