Senior Static Timing Analysis (STA) Developer

Job Details:

Job Description:

We are seeking an experienced Senior Static Timing Analysis (STA) Developer to architect, design, and optimize next-generation timing analysis engines for advanced ASIC and FPGA design flows. This role is ideal for someone who has deep expertise in STA algorithms, large-scale EDA software development, and performance-driven optimization. You will play a key role in building industry-leading STA solutions capable of handling massive SoC designs, complex clocking structures, and modern multi-threaded compute environments.

Key Responsibilities

Core STA Engine Development

• Architect and develop high-performance STA engines for ASIC and FPGA design flows.
  
• Enhance graph-based timing analysis algorithms to support complex clock trees, timing exceptions, and multi-domain clocking.
  
• Improve path search algorithms to reduce memory footprint and accelerate timing path generation.
  
• Ensure high correlation and competitive performance relative to industry-leading STA tools.
  

Performance, Scalability & Optimization

• Identify and eliminate runtime bottlenecks across timing and logic optimization flows.
  
• Optimize PPA-critical components to achieve best-in-class accuracy and runtime balance.
  
• Implement advanced data structures, dynamic memory management, and disk-caching strategies to support extremely large IC designs (100M+ gates, thousands of clock domains).
  
• Drive multi-threading enhancements and parallelization strategies for modern compute architectures.
  

Software Infrastructure & Debugging

• Refactor and modernize codebases to improve maintainability, scalability, and multi-thread performance.
  
• Build robust debugging and diagnostic infrastructure to capture detailed customer-side failure information.
  
• Rapidly root-cause and resolve complex timing and infrastructure issues based on limited customer feedback.
  

Cross-Tool Integration & EDA Ecosystem Support

• Develop and maintain interfaces between STA engines and synthesis, P&R, and other EDA tools.
  
• Ensure data integrity and compatibility across internal and external toolchains.
  
• Collaborate with synthesis and optimization teams to deliver cohesive end-to-end timing closure solutions.
  

Customer & Product Support

• Support customer tape-outs by ensuring STA robustness, accuracy, and runtime efficiency.
  
• Work with field teams to diagnose customer issues and deliver timely fixes or enhancements.
  
• Contribute to product roadmap discussions based on customer needs and industry trends.
