SoC Timing (Static Timing Analysis/STA) Engineer, HBM

Key Responsibilities 

• Responsibilities will include, but are not limited to:

  • Own end-to-end chip-level static timing analysis and sign-off across all checks, modes, corners, and voltage and temperature conditions.
  • Develop, maintain, and validate sign-off quality Synopsys Design Constraints (SDC) for clocks, resets, high-bandwidth memory (HBM) interfaces, design for test (DFT), and configuration logic.
  • Drive timing closure at block, subsystem, and full-chip levels through critical path analysis, engineering change orders (ECOs), and close collaboration with physical design on placement, clock tree synthesis, and routing.
  • Perform multi-mode, multi-corner (MMMC) analysis including clock domain crossing timing, on-chip variation (OCV, AOCV, POCV), and advanced-node timing methodologies.
  • Lead signal integrity and crosstalk analysis, identify noise-induced timing issues, and partner with physical design teams on mitigation strategies.
  • Build and maintain static timing analysis automation and flows using Python and Tcl for reporting, regression tracking, quality of results dashboards, and sign-off readiness.
  • Conduct post-silicon timing correlation while defining and driving organization-wide static timing analysis methodology, sign-off standards, timing closure best practices, readiness reviews, and tape-out sign-off gates, clearly communicating timing status, risks, and closure plans to design leads and senior management.
  • Mentor and grow junior engineers, contribute to design documentation and timing sign-off artifacts, and collaborate cross-functionally with Physical Design, RTL Design, Verification, Design for Test, Product Engineering, and Test teams to ensure timing requirements are met throughout the design cycle.

  Minimum Qualifications:

  • 10+ years of hands-on experience owning chip-level static timing analysis and full timing sign-off on multiple tape-outs at 5nm or below.
  • Deep expertise with industry-standard static timing analysis tools such as Synopsys PrimeTime and/or Cadence Tempus.
  • Expert understanding of advanced timing concepts including multi-mode multi-corner analysis, on-chip variation, signal integrity, and power-aware timing.
  • Proven ability to develop and manage complex hierarchical SDC constraints for large systems on chip with multiple clock and power domains.
  • Proficiency in Python and/or Tcl scripting for timing flow automation, constraint management, and quality of results reporting.

  Preferred Qualifications:

  • Experience with high-bandwidth memory (HBM), dynamic random-access memory (DRAM), or memory-centric system-on-chip designs.
  • Exposure to design for test timing, including scan, memory built-in self-test (MBIST), and Joint Test Action Group (JTAG) interfaces.
  • Experience with chiplet-based or three-dimensional integrated circuit designs and die-to-die interface timing methodologies.
  • Familiarity with foundry process design kits, Liberty timing models, and advanced noise and variation modeling.
  • Strong communication skills with the ability to present timing status, risks, and sign-off readiness to cross-functional teams and senior leadership.
