Key Responsibilities

• Own SI analysis, simulation, and design closure for CXL 2.0/3.0 interfaces, including channel budget development, equalization strategy, and margin analysis.
• Own SI analysis and design guidelines for GPIO and LSIO interfaces, including signal integrity characterization, termination, and compliance.
• Collaborate with SoC, applications engineering, packaging, and system design teams to define and implement system interconnects that meet the unique demands of high-end server environments.
• Contribute to SI guidelines and provide feedback on PCB stack-ups, routing constraints, via structures, and material selection for CXL and LSIO interfaces.
• Contribute to the development of server-grade SI models, simulations, and final designs across assigned interface domains.
• Perform SI analysis on 2.5D/3D structures and contribute to the establishment of design guidelines for advanced packaging integration.
• Support customer-facing SI collateral development - guidelines, application notes, and simulation models for CXL and LSIO interfaces. NEW
• Update and automate design and analysis flows using scripting tools.
• Prepare and present technical documentation and reports to stakeholders, including engineering teams, senior management, customers, and suppliers.

Minimum Qualifications

• Expertise in CXL 2.0/3.0 specifications and/or PCIe Gen5+ SerDes standards, including channel simulation and compliance methodology.

• Experience with GPIO, LSIO, and low-speed interface SI characterization and design guidelines.

• Familiarity in DDR5/LPDDR5X JEDEC specifications and/or SerDes standards (PCIe, CXL, USB, Ethernet, etc.).

• Experience in developing SI methodologies from die to system, with lab correlation and validation.

• Proficiency with 2D/2.5D/3D EM simulation tools such as ANSYS HFSS, Cadence Sigrity, Dassault Systèmes CST, Keysight ADS, and Synopsys' HSPICE.

• Hands-on experience creating complex SI models and performing both frequency and time-domain simulations.

• Proficiency in Unix/Linux environments and experience with EDA tools through scripting.

• Strong knowledge of packaging and PCB technologies, design, and manufacturing processes.

• Familiarity with 2.5D/3D packaging technologies, such as CoWoS, InFo, EMIB, and RDL.

• Hands-on experience with electrical validation and compliance testing using tools like VNAs, oscilloscopes, spectrum analyzers, PCIe/CXL analyzers, traffic generators, TDR, and differential probes.

• Proven ability to work independently and collaboratively within a cross-functional team environment.

• Strong technical documentation skills and excellent written and verbal communication.

Preferred Qualifications

• Ph.D. in Electrical or Computer Engineering, specializing in SI.

• 12+ years of experience in SI analysis, simulation, and measurement of high-speed digital systems.

• In-depth understanding of computational electromagnetics and transmission line theory.

• Hands-on experience with CXL 2.0/3.0 channel simulation, compliance testing, and debug on server-class platforms.

• Proficiency in DDR5 and LPDDR5X timing budgets, jitter analysis, and PHY design/link analysis.
