About the role

Role focused on timing closure for highly complex GPU designs within Apple’s Silicon Engineering group. Drive STA activities, collaborate across RTL, Architecture, Synthesis, DFT, and Physical Design, and support tapeout and post-silicon activities to ensure high-quality silicon and timing convergence.

Responsibilities

  • Lead different STA activities at the same time by working with functional collaborators
  • Identify dependencies and roadblocks for different STA items very early on and ensure a smooth execution of timing closure
  • Participate in analysis leading to the definition of next generation products
  • Interact with RTL, architecture teams to understand physical design constraints related to timing and be the central point of contact to provide these to backend design flows
  • Work with Synthesis and Physical Design teams to implement the best design optimized for power, performance and timing
  • Setting up all DFT modes and making sure all test features are properly timed
  • Assemble the top level design for STA ensuring accurate analysis by reviewing all the logs and reports
  • Create and maintain scripts and automation to ensure high quality STA reports and work with other teams for timing closure
  • Run ECO flows on the design and responsible for close timing
  • Drive and support tapeout activities by running a full suite of signoff checks to ensure a high quality silicon for manufacture
  • Work with CAD and Vendors to constantly improve the flow and bring in groundbreaking features to the analysis flows
  • Work with post silicon teams and product engineering for silicon debug activities

Qualifications

  • Bachelors degree in Computer Science or Computer Engineering + 10 years relevant experience
  • Experience in STA and leading timing closure efforts
  • Experience with STA concepts such as cross-talk, OCV, noise, etc.
  • Experience with scripting languages like TCL, Python, Perl, shell scripting etc.
  • Experience working with EDA tools and exposure to their APIs
