Help define how AI can triage and fix signoff violations.
What We’re Looking For
5+ years of physical verification or signoff experience on production tapeouts.
Deep experience with Calibre or IC Validator.
Experience with RedHawk or Voltus for IR/EM analysis.
Strong understanding of foundry rule decks at advanced nodes.
Tcl, Python, or SVRF scripting.
