Job Summary

The Role:

We are seeking a Power Integrity Simulation Engineer to own the modeling simulation and optimization of the power delivery network (PDN) for our accelerator boards. You will work closely with power board design and package teams to ensure stable lownoise power for highcurrent accelerator SoCs and memory operating at leadingedge process nodes.

Key Responsibilities:

Develop detailed PDN models for accelerator boards (VRM to die) including planes vias decoupling capacitors connectors and packages.
Perform frequencydomain and timedomain PI simulations to:
Optimize decoupling strategy
Control impedance over target frequency ranges
Minimize voltage droop noise and resonances
Collaborate with power and PCB teams to drive layout guidelines and stackup decisions based on PI analysis.
Work with SI engineers to understand coupling between highspeed interfaces and PDN.
Support power design engineers in component selection (VRMs bulk and ceramic caps ferrites etc.).
Correlate simulation results with lab measurements (Bode plots impedance transient response).
Provide PI constraints and signoff criteria for new designs and design revisions.
Document simulation methodologies models and results; create reusable templates and flows for future programs.

Minimum Qualifications:

Bachelors or Masters degree in Electrical Engineering or related field.
3 years of experience in Power Integrity or closely related SI/EMC roles at the board or package level.
Handson experience with PI simulation tools (e.g. CADENCE PowerSI PowerDC OptimizePI VRM simulation (SIMetrix/SIMPLIS) etc.).
Solid understanding of:
PDN design concepts target impedance and decoupling strategies
Transmission line theory return paths and via behavior
Ability to interpret and generate Sparameters and SPICE models.
Experience working with PCB stackup definitions and working with layout teams.

Preferred Qualifications:

Experience supporting highcurrent highpower accelerators CPUs GPUs or FPGAs.
Familiarity with package/board cosimulation flows.
Experience with lab validation of PDN characteristics (vector network analyzers current probes etc.).
Scripting skills (Python MATLAB or similar) for data analysis and flow automation.
