Power Integrity Senior Staff Engineer

Job Title

Power Integrity Senior Staff Engineer

Role Summary

Senior engineer responsible for leading power integrity (PI) analysis across die, package, and PCB for UCIe PHY and other high-speed I/O systems. Work closely with PHY, package, PCB, and signal integrity teams to define PI targets, validate models, and support silicon bring-up.

Experience Level

Senior — role expects an experienced engineer (seniority indicated by job title). The posting references 5+ years of hands-on experience in Power Integrity or high-speed interface design.

Responsibilities

Lead technical PI activities from requirements through sign-off; collaborate across disciplines to ensure robust power delivery in multi-gigabit interfaces.

• Lead end-to-end PI analysis across die, package, and PCB (VRM to on-die power grid).
• Develop and optimize Power Delivery Network architecture; perform DC IR drop, AC impedance, transient, and resonant analyses.
• Build and validate electrical models for silicon, package substrates, PCBs, decoupling capacitors, and voltage regulators (S-parameters, IBIS, SPICE).
• Define target impedance requirements; analyze simultaneous switching noise, ground bounce, and power-induced jitter.
• Collaborate with package, PCB, signal integrity, and PHY teams to optimize decoupling strategies and power distribution topologies.
• Support silicon bring-up by correlating lab measurements with simulations and refining models.

Requirements

Core technical skills and tool experience required for the role.

• Deep understanding of Power Delivery Network design, including DC IR drop, AC impedance, transient analysis, and resonance mitigation.
• Proven experience with die-package-board co-design for high-speed interfaces (UCIe, PCIe, DDR, SerDes, HBM).
• Proficiency with PI and EM tools such as Cadence Sigrity, Ansys SIwave, Ansys HFSS, Ansys RedHawk-SC, Keysight ADS, or PowerSI.
• Strong working knowledge of S-parameters, IBIS/IBIS-AMI modeling, SPICE simulation, and frequency-domain analysis.
• Scripting experience for automation and data analysis (Python, Tcl, or MATLAB).
• Ability to translate requirements between PHY, package, and PCB teams and to debug model discrepancies.

Education Requirements

Master's or Ph.D. in Electrical Engineering (field specified). The posting pairs this with 5+ years of hands-on experience in Power Integrity or high-speed interface design.
