Staff Signal Integrity Engineer, Infrastructure Hardware

Job Title

Staff Signal Integrity Engineer, Infrastructure Hardware

Role Summary

Own signal integrity (SI) and power integrity (PI) methodology, design, analysis, and validation for Meta's data-center platforms (AI, networking, compute, storage). Collaborate with hardware design, silicon teams, and manufacturing partners to ensure reliable high-speed data transmission across electrical and optical interconnects.

Define SI/PI standards, guide platform architecture trade-offs, and deliver deployable channel solutions at board and system levels.

Experience Level

Senior — Staff-level role. Minimum 8+ years of experience in signal integrity engineering for high-speed digital systems.

Responsibilities

Primary responsibilities include:

• Develop SI/PI solutions across AI, networking, compute, and storage platforms.
• Perform signal integrity simulations and validation at platform, board, and system levels using tools such as HSpice, ADS, or Sigrity.
• Develop and maintain channel models, IBIS-AMI models, and S-parameter extraction workflows for end-to-end electrical-optical-electrical channels.
• Define and integrate on- and off-chip interconnect technologies into scalable systems.
• Specify stackup requirements, routing constraints, via structures, and impedance targets for multilayer high-speed designs.
• Lead lab correlation and validation activities using TDR, VNA, and oscilloscope measurements to verify simulations and characterize channels.
• Partner with silicon vendors and internal ASIC teams on PHY specifications, equalization parameters, and link training behavior.
• Establish SI design guidelines, review processes, and sign-off criteria across the infrastructure hardware portfolio.
• Identify systemic SI risks early and drive architectural trade-off decisions with platform and mechanical teams.
• Mentor engineers on SI principles, simulation best practices, and measurement techniques.

Requirements

Must-have qualifications and skills (education is listed separately below):

• 8+ years of experience in signal integrity engineering for high-speed digital systems, including board- and system-level SI/PI analysis.
• Experience with PCB board-level design and layout and high-speed interconnects using merchant silicon ASICs.
• Experience working with ODMs and contract manufacturers.
• Proven track record of conceptualizing and delivering engineering solutions to customers.
• Programming experience for test/measurement automation and/or simulation scripting.
• Strong lab measurement skills and experience correlating simulation with TDR, VNA, and oscilloscope data.
• Ability to collaborate across platform architecture, hardware, and mechanical engineering teams.

Nice-to-have:

• Experience with 112G/224G PAM4 SerDes channel design, co-packaged optics, and optical channels for data center networking.
• Background in open compute or hyperscale data center hardware development across full platform cycles.
• Familiarity with IBIS-AMI modeling, channel simulation automation, and statistical eye analysis.
• Experience collaborating with silicon vendors on SerDes bring-up, equalization tuning, and compliance testing.
• Knowledge of advanced PCB materials, HDI, and evolving interconnect technologies.

Education Requirements

Bachelor's degree in Electrical Engineering, Computer Science, Computer Engineering, or a related technical field, or equivalent practical experience. (Equivalent practical experience is explicitly accepted.)
