Signal and Power Integrity Engineer

Google Google · Big Tech · Sunnyvale, CA +1

This role focuses on Signal and Power Integrity (SI/PI) engineering for custom silicon solutions in Google's direct-to-consumer products. The engineer will be responsible for chip package design, SI/PI simulation and characterization at chip, package, and system levels, working within a concurrent engineering environment with cross-functional teams. Key responsibilities include driving SI/PI analysis and optimization for HPC, leading the development of next-generation memory interfaces, managing post-silicon validation, and partnering with design teams and vendors to meet electrical requirements.

What you'd actually do

  1. Drive SI/PI analysis and optimization for HPC based on 2.5D/3D technology, influencing product definition, chip floorplan, power tree structures, and netlists.
  2. Lead the development of next-generation memory interfaces and evaluate high-speed interface IP, considering Input/Output Physical Layer (IO PHY), physical design, and SI/PI requirements.
  3. Manage post-silicon validation and qualification of high-speed interfaces for New Product Introduction (NPI), ensuring performance meets production standards.
  4. Partner with chip/system design teams and external vendors to define SI/PI design goals, set chip boundaries, and balance SI/PI and DFM tradeoffs for production closure.
  5. Develop innovative methodologies to enhance simulation accuracy and productivity while providing critical feedback on chip floorplans to optimize routability and signal integrity.
