About the role

Senior / Principal Power Integrity Engineer to own and drive power delivery strategies for 2.5D/3D heterogeneous integration, focusing on robust, low-noise, high-efficiency PDNs for AI compute infrastructure leveraging co-packaged optics, silicon photonics, and chiplet architectures.

Responsibilities

  • Define and implement power integrity architectures for 2.5D/3D heterogeneous integration, including chiplet-based designs, interposer/substrate scaling, on-package voltage regulation, multi-rail PDN topologies, decoupling strategies, and power-aware thermal co-design.

Qualifications

  • Deep expertise in power integrity for high-performance semiconductors, with strong knowledge of PDN design principles, frequency-domain analysis, transient response, on-chip/off-chip decoupling, IR drop/EM analysis, and noise mitigation techniques.
  • Proven track record leading power integrity efforts in advanced packaging environments, including 2.5D/3D integration, chiplets, silicon interposers/bridges, FOWLP, CoWoS, hybrid bonding, or similar technologies.
  • Bachelor’s degree in Electrical Engineering, Physics, or related field + 10+ years relevant industry experience; or Master’s/PhD + 7+ years related experience.
  • Hands-on proficiency with PI simulation tools (Ansys, Cadence/Sigrity, Keysight ADS, Apache/RedHawk, or equivalents) and correlation to silicon measurements.
  • Strong understanding of chip-package-system interactions, high-speed signaling impacts on PDN, power-aware design for AI/HPC workloads, photonic interconnects and optical engines, and reliability failure mechanisms (e.g., EM, TDDB under high current densities).
  • Demonstrated ability to lead complex, cross-functional programs across global teams, foundries, OSATs, and suppliers.
  • Excellent communication, presentation, and documentation skills to influence stakeholders and drive technical alignment.
