About the role
We are seeking a skilled and detail-oriented Power Integrity (PI) Engineer to join our high-performance engineering team. In this role, you will analyze, simulate, and optimize power delivery networks (PDN) for next-generation high-speed systems, with a focus on interconnects. You will collaborate closely with signal integrity, PCB design, and hardware teams to ensure robust power delivery that meets impedance requirements, with potential additional considerations for noise and ripple. The role may also involve evaluating shielding for EMI/EMC remediation. This is a hands-on engineering position requiring strong technical skills, creative problem-solving, and cross-functional collaboration in a fast-paced environment.
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.
Requirements
- 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 (e.g., 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.
Skills
- Familiarity with high-speed digital systems (SerDes, DDR, PCIe).
- Knowledge of EMI/EMC compliance testing and mitigation techniques.
- Background in scripting or automation (MATLAB, Python) for data analysis.
- Experience with lab instrumentation: VNAs, oscilloscopes, spectrum analyzers.
