Design Engineer - STA

Broadcom is seeking a Design Engineer for their Custom Silicon Design Team in Fort Collins, Colorado. This role focuses on Static Timing Analysis (STA) for advanced ASICs in deep sub-micron technologies, including 3nm and smaller process nodes. The engineer will be responsible for chip-level timing architecture, analysis, and closure for high-performance SoC designs in AI, computing, and networking products, working from concept through production.

Must Have

• Develop, validate, and maintain timing constraints for complex SoC designs across multiple modes and corners.
• Perform static timing analysis (STA) using industry-standard tools such as Synopsys PrimeTime or Cadence Tempus.
• Define and execute timing signoff methodologies, including process corners, derates, and uncertainties.
• Conduct pre- and post-route timing analysis, quality of results (QoR) evaluations, and closure verification.
• Generate and validate timing ECOs to achieve signoff-quality closure across PVT corners.
• Automate timing flows and analysis using Tcl and scripting languages such as Perl or Python.
• Collaborate with physical design, synthesis, and clock teams to ensure timing convergence and cross-domain consistency.
• Analyze and debug timing violations, signal integrity issues, and clock network challenges.
• Support power and performance optimization through informed timing analysis and constraint tuning.
• Ensure full compliance with timing signoff checklists, methodology, and documentation.
• BS in Electrical or Computer Engineering with 12+ years of relevant experience, or MS with 10+ years of relevant experience.

Good to Have

• Proficiency in Python, Perl, or Ruby.
• Hands-on experience with Synopsys and/or Cadence STA tools.
• Exposure to advanced STA techniques, including POCV/SOCV/LVF, PBA, and SPICE correlation.
• Knowledge of timing libraries (CCS/ECSM/NLDM) and multi-input switching (MIS) effects.

Perks & Benefits

• Medical plan
• Dental plan
• Vision plan
• 401(K) participation including company matching
• Employee Stock Purchase Program (ESPP)
• Employee Assistance Program (EAP)
• Company paid holidays
• Paid sick leave
• Vacation time
• Paid Family Leave
