About the role

Senior SI/PI Engineer focused on chip package and PCB design analysis for high-speed mixed-signal systems, including DP2.1, PCIe Gen6, and 100GbE+, with responsibilities spanning PDN design, SI/PI modeling, and cross-functional collaboration.

Responsibilities

  • Work on crafting creative Signal and Power Integrity solutions to complex system design problems
  • System-level power integrity simulations of NVlinks 200Gbs+, PCIe, and other HSIO such as DP2.1/HDMI2.1/CSI/USB4
  • Design and optimize Power Delivery Network (PDN) across interposers, packages, and PCBs
  • SI channel analysis for spec development: DP2.1/HDMI FRL2
  • Constant improvements of SI/PI models through lab measurements
  • Simulation automation, data gathering, analysis and visualization using JMP, MATLAB or similar tools
  • Opportunity to work in dynamic cross-functional role to optimize package, PCB, ASIC, mixed signal circuit
  • Post-layout SI/PI model extraction for project review sign-off

Qualifications

  • BS/MS-Electrical Engineering or equivalent experience
  • 5+ years of industry experience
  • Strong understanding of electromagnetics including transmission line theory and via properties, and the SI/PI/EMI applications; S/Y/Z parameters; discrete signal processing knowledge
  • Hands on use of 3/2.5-D modeling tools like ANSYS HFSS/Q3D/SIwave, Cadence PowerSI
  • Experience with PDN evaluation using layout extraction tools for packages and PCBs and spice-based time domain simulations for power noise
  • Experience with die power delivery modeling – mixed-signal blocks & digital and associated tools like CSM/Redhawk, Raptor-X
