Signal/Power Integrity Engineer (On-/Off-Chip)

Responsibilities Define SI/PI requirements based on IP and system-level specifications. Perform SI/PI simulations at electromagnetic (EM), circuit, and system levels. Develop SI/PI methodologies for advanced packaging technologies such as chiplet, 3D-IC, D2D (die-to-die), and C2C (chip-to-chip) interfaces. Cover SI/PI analysis and optimization at the full system level, including on-chip, package, and PCB domains. Provide design guidance on stack-up, interconnect routing, PDN architecture, decoupling strategy, and component selection. Collaborate with silicon, package, and board teams to ensure accurate measurement-simulation correlation and system-level robustness. Support debug and bring-up efforts in the lab when needed. Work with internal teams and partners to co-optimize SI/PI solutions. Minimum Qualifications BS or MS in Electrical Engineering, Physics, or a related field. 8+ years of experience in component- and system-level SI/PI analysis. Solid understanding of SI/PI fundamentals and methodologies. Hands-on experience with lab instruments such as VNA, TDR, and real-time oscilloscopes. Proficient in EDA tools such as SIwave, HFSS, ADS, HSPICE, Allegro, RedHwak-SC, SC-ET, or RedHawk-3DIC. Preferred Qualifications PhD in Electrical Engineering, Physics, or a related field with 5+ years of relevant industry experience. Candidates with one or more of the following experiences will be given strong consideration: SI/PI analysis and optimization for high-speed digital systems and standard interfaces (e.g., PCIe, DDR, Ethernet) Model and analyze complex 3D structures using EM simulation tools On-chip Backend sign-off (Static/Dynamic IR, EM) On-/Off-chip PDN modeling and budgeting On-chip glitch/jitter/DVD analysis and sign-off methodology, including cross-talk, TSV uncertainty, and multi-corner/process derating Early-stage reference clock jitter estimation and sign-off methodology development Experience with on-chip clock sign-off, including clock design guide, 3DIC jitter derating, and multi-corner/process variation analysis.
