Senior Signal and Power Integrity Engineer

Job Title

Senior Signal and Power Integrity Engineer

Role Summary

Engineer responsible for signal and power integrity analysis for chip, package and PCB designs to support high-speed interfaces (e.g., NVLink, PCIe Gen6, DP2.1, 100GbE). Works with cross-functional hardware teams to deliver simulation, measurement correlation, PDN and SI solutions for high-speed mixed-signal systems.

Role is execution-focused and involves hands-on modeling, simulation automation, lab measurement, and interaction with package/ASIC/PCB design groups.

Experience Level

Senior — 5+ years of industry experience in signal and power integrity or related electrical engineering roles.

Responsibilities

Principal responsibilities include system-level SI/PI analysis, PDN design, and measurement correlation supporting high-speed interfaces.

• Develop SI/PI solutions for complex system designs and high-speed interfaces (NVLink, PCIe, DP2.1/HDMI, CSI, USB4, 100GbE).
• Perform system-level power integrity simulations across interposers, packages, and PCBs; design and optimize PDNs.
• Conduct SI channel analysis to support specification development and model improvement through lab measurements.
• Perform post-layout SI/PI model extraction and prepare results for design reviews and sign-off.
• Automate simulations, data collection, analysis and visualization using tools such as JMP, MATLAB or similar.
• Work cross-functionally to optimize interactions between package, PCB, ASIC and mixed-signal circuit designs.

Requirements

Key must-have technical skills and practical experience. Educational degree requirements are listed separately below.

Must-have:

• Strong understanding of electromagnetics, transmission line theory, via behavior, SI/PI/EMI concepts and S/Y/Z parameter analysis.
• Hands-on experience with 3D/2.5D EM and SI tools such as ANSYS HFSS, Q3D, SIwave or Cadence PowerSI.
• PDN evaluation experience using layout extraction tools and time-domain SPICE-based simulations for power noise analysis.
• Die power-delivery modeling experience and familiarity with tools such as CSM/Redhawk or Raptor-X.
• Familiarity with voltage regulator and board power-supply modeling (Simplis or SPICE) and lab instruments (VNA, TDR, DSO).
• Experience correlating measurement and simulation results; knowledge of transient simulations and eye-diagram methodology.

Nice-to-have:

• Experience with MATLAB, Python, VBS, or C for simulation automation and data analysis.
• Exposure to interface timing budgets, system modeling, and SI/PDN analysis flows including co-simulation techniques.
• Familiarity with high-speed I/O design topics (clock generation, transmitter/receiver design, equalization) and high-volume manufacturing variation impacts.

Education Requirements

BS or MS in Electrical Engineering or equivalent practical experience.
