Static Timing Analysis Engineer

Santa Clara Valley (Cupertino), California, United States


Role Number:200171774
Join Apple’s growing wireless silicon development. In this highly visible role, as part of a highly talented team you will be at the heart of the wireless chip design effort interfacing with all disciplines (vertical product model) with critical impact in getting functional products to millions of customers quickly.

Key Qualifications

  • The position requires thorough knowledge of the ASIC design timing closure flow and methodology. The ideal candidate will have the following background:
  • At least 5+ years hands-on experience in ASIC timing constraints generation and timing closure.
  • Expertise in STA tools (such as Primetime) and methodologies for timing closure with a good understanding of OCV, noise and cross-talk effects on timing.
  • Familiarity with all aspects of timing closure of high-performance, mixed-signal SoCs in advanced process technology nodes (28nm and below).
  • Knowledge of timing corners/modes and process variations.
  • Knowledge of low-power techniques including clock gating, power gating and multi-voltage designs.
  • Proficient in scripting languages (Tcl and Perl).
  • Strong communication skills are a pre-requisite as the candidate will interface with a lot of different groups (e.g. digital design, verification, DFT, physical design, etc.).
  • Self starter and highly motivated.
  • Familiarity with RTL, synthesis, logic equivalence, DFT, floor-planning, and backend related methodology and tools.


As a Wireless ASIC STA engineer, you will be a part of the Wireless SOC digital design team responsible for providing integrated solutions for wireless chips. Responsibilities include: Full chip and block level timing closure ownership throughout the entire project cycle (RTL, synthesis, and physical implementation). Develop and maintain methodology and flows related to timing verification and closure. Generation of block and full chip timing constraints. Analyze timing reports and utilize scripting techniques to develop insights and drive rapid timing closure. Support digital chip integration work and flows.
