HBM SI/PI Principal Engineer

Job Title

HBM SI/PI Principal Engineer

Role Summary

Senior technical authority for signal integrity (SI) and power integrity (PI) in High Bandwidth Memory (HBM) systems within the Heterogeneous Integration Group. The role drives system-level SI/PI architecture, analysis methodologies, and sign-off criteria across 2.5D and 3D interposer-based designs.

This position supports design and deployment of HBM-enabled platforms for AI/ML applications and requires end-to-end ownership from modeling through production sign-off.

Experience Level

Senior - minimum 7 years of relevant SI/PI modeling and analysis experience; 10+ years preferred.

Responsibilities

Accountable for SI/PI technical leadership across package, interposer, and PCB domains.

• Lead signal integrity channel analysis for 2.5D and 3D interposers using frequency- and time-domain methods.
• Define and drive power delivery architecture, impedance targets, and transient PDN analysis.
• Perform electromagnetic extraction and modeling across PCB, package, and interposer stacks.
• Establish SI/PI standards, methodologies, and sign-off criteria for HBM system designs.
• Provide clear technical direction and decisions in ambiguous or incomplete design environments.
• Influence cross-team architecture and ensure designs meet performance, reliability, and scalability targets.

Requirements

Must-have technical skills and experience required for independent ownership of SI/PI for HBM systems.

• Must-have: 7+ years of experience in signal integrity and power integrity modeling and analysis.
• Must-have: Strong fundamentals in electromagnetics, transmission line theory, and I/O design.
• Must-have: Hands-on experience with industry SI/PI EDA tools (examples: ANSYS, Synopsys, Cadence, Keysight).
• Nice-to-have: 10+ years of SI and PDN modeling and analysis experience.
• Nice-to-have: Experience with 2.5D/3D advanced packaging and interposer-based designs.
• Nice-to-have: Background with high-bandwidth interfaces such as HBM, DDR, SERDES, or UCIe.
• Nice-to-have: Direct ownership of system-level SI/PI sign-off for production silicon.
• Nice-to-have: Scripting experience to automate SI/PI flows (TCL and/or Python).
