Senior Power Integrity Engineer for High Speed PDN

Amphenol Corporation; Nashua (NH); On-site; USD 100,000 - 150,000; Full time

Job summary

Amphenol Communications Solutions (ACS), a division of Amphenol Corporation, seeks a Power Integrity Engineer to analyze, simulate, and optimize power delivery networks for high-speed systems. You will collaborate with signal integrity and PCB teams to ensure robust PDN performance and EMI/EMC mitigation.

The role emphasizes hands-on PDN simulations, lab validation, and cross-functional teamwork in Nashua, NH. A strong background in PDN impedance and decoupling is essential.

Qualifications

• Bachelor's degree in Electrical Engineering or related field; Master’s preferred.
• 3+ years of experience in power integrity, signal integrity, or hardware design.
• Hands-on experience with PDN simulation tools (Keysight PIPro, ANSYS Q3D, HFSS, SIwave, Cadence Sigrity PowerSI).
• Experience with SPICE simulation and transient load modeling.
• Strong understanding of PDN impedance, VRM behavior, and decoupling network design.
• Proficiency in PCB stack-up design, power plane resonance control, and capacitor optimization.
• Excellent analytical, communication, and documentation skills.

Responsibilities

• Perform power integrity simulations (AC impedance, DC IR drop, and transient analysis) to ensure PDN performance.
• Design and optimize decoupling strategies, capacitor selection, and placement for complex boards and systems.
• Interact with customers to determine their power interconnect needs.
• Perform EMI/EMC risk assessments related to power distribution.
• Collaborate with SI engineers to co-optimize power and signal integrity.
• Develop PDN models and validate through lab measurements (VNA impedance sweeps, oscilloscope ripple measurements).
• Work with PCB designers on layer stack-up, plane assignments, and power routing.
• Assist in root-cause analysis and debugging of customer power-related issues.
• Document best practices and contribute to design guidelines for power delivery networks.
