About the role

Custom Logic Design and STA engineer role in Apple’s Analog/Mixed Signal Design team. Focus on timing analysis, STA constraints, and design of analog/mixed-signal custom logic in high-speed chips, collaborating with RTL, CAD, and verification teams.

Responsibilities

  • Custom design timing closure ownership throughout the entire project cycle.
  • Develop and implement STA constraints from specs.
  • Perform block- and chip-level static timing and noise analysis.
  • Design and characterize transistor- and gate-level custom digital circuits in mixed-signal chips.
  • Work with RTL and custom design teams on timing changes and propose correct-by-construction designs and methodologies.
