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.

• Masters 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 Ser Des standards (PCIe, CXL, USB, Ethernet, etc.).
