Position: Signal Integrity Architect

We are seeking an experienced Signal Integrity Architect (individual contributor) to develop high-performance signal integrity (SI) solutions tailored for advanced server applications. In this role, you will work closely with the platform team and collaborate with cross-functional teams, including software, firmware, packaging, product management, and component suppliers. You will lead the definition, analysis, and verification of SI for high-speed interconnects across die, interposer, package, PCB, and system levels for data center servers.

Key Responsibilities

• 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.
• Provide guidelines and feedback on silicon timing, bump/RDL, package pinout and PCB specifications.
• Develop customer guidelines and define module interfaces/formats for simulation.
• Lead the creation of server-grade SI models, simulations, and final designs.
• Perform early SI analysis on 2.5D/3D structures and establish design guidelines.
• Update and automate design and analysis flows.
• Prepare and present technical documentation and reports to stakeholders, including engineering teams, senior management, customers, and suppliers.

Minimum Qualifications

• Master’s degree in Electrical or Computer Engineering, with a specialization in Signal Integrity (SI).
• 6+ years of experience in SI analysis, simulation, and measurement of high-speed digital systems.
• Strong knowledge of SI fundamentals, including power distribution networks (PDN), EMIR, transmission line theory, crosstalk, S-parameters, and channel simulations.
• Expertise 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/I2C 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.
• 10+ years of experience in SI analysis, simulation, and measurement of high-speed digital systems.
• In-depth understanding of computational electromagnetics and transmission line theory.
• Proficiency in DDR5 and LPDDR5X timing budgets, jitter analysis, and PHY design/link analysis.
• Experience with SI simulation for PCIe Gen6+, multi-gigabit serial buses (112Gbps+), UCIE, etc.
• Experience with package and PCB design tools such as Cadence Allegro.
• Proficiency in scripting with MATLAB, Perl, and Python.
