  • Define package specifications, bump map and ball map, interposer requirements, and mechanical constraints.
  • Define substrate stack‑ups, bump pitch, ball pitch, routing, via structures, and material choices for performance and manufacturability.
  • Perform high-speed signal escaping, routing and power distribution network design.
  • Manage subcontractors and work directly with TSMC and/or OSAT on bumping, substrate options, and advanced packaging flows.
  • Partner with IC design, physical design, SI/PI, and board teams to ensure package requirements meet system‑level needs.
  • Evaluate emerging packaging technologies and drive adoption for next‑generation products.
  • Support package‑level bring‑up, failure analysis, debug and qualification.

Required Skills & Qualifications

  • B.S./M.S. in Electrical Engineering or related field.
  • Experience with multi‑die package design and UCIe (AP/SP) integration.
  • Understanding of substrate materials, stack‑ups, and mechanical constraints.
  • Familiarity with SI/PI concepts to collaborate effectively with electrical teams.
  • Experience managing packaging subcontractors.
  • Experience interfacing with TSMC/OSAT for bumping and packaging options.
  • Knowledge of package modeling tools (HFSS, Sigrity, or similar) is a plus.
