About the role

Meta is seeking a Signal Integrity Engineer to drive the design and validation of high-speed interconnects across data center platforms, defining SI/PI standards and collaborating with hardware, silicon teams and industry partners to support scalable infrastructure.

Responsibilities

  • Develop next-generation SI/PI solutions across a broad range of Meta platforms, including AI, network, compute, and storage systems
  • Perform signal integrity simulations, implementation, validation, and test methodologies at the platform, board, and system levels using industry-standard tools such as HSpice, ADS, or Sigrity to validate channel performance and margins
  • Develop and maintain channel models, IBIS-AMI models, and S-parameter extraction workflows for board-level and system-level SI analysis, including end-to-end electrical-optical-electrical channels
  • Define the next generation of open on- and off-chip interconnect technologies and integrate these into highly scalable, deployable, and maintainable systems
  • Collaborate with design and manufacturing teams to define stack-up requirements, routing constraints, via structures, and impedance targets for multi-layer high-speed designs
  • Drive lab correlation and validation activities, including TDR, VNA, and oscilloscope-based measurements, to verify simulation accuracy and characterize channel performance
  • Partner with silicon vendors and internal ASIC teams to evaluate PHY specifications, equalization parameters, and link training behavior for new interface standards
  • Establish design guidelines, review processes, and SI sign-off criteria adopted across Meta's infrastructure hardware portfolio
  • Identify systemic signal integrity risks early in the design cycle and drive architectural trade-off decisions with hardware platform and mechanical engineering teams
  • Mentor other engineers on signal integrity principles, simulation best practices, and measurement techniques to elevate the team's technical capabilities

Qualifications

  • Bachelor's degree in Electrical Engineering, Computer Science, Computer Engineering, or a relevant technical field, or equivalent practical experience
  • 8+ years of experience in signal integrity engineering for high-speed digital systems, including board-level and system-level SI/PI analysis
  • Experience with PCB board level design and layout, high-speed interconnect and switching using merchant silicon ASICs
  • Experience designing and delivering signal integrity solutions from concept through production deployment
  • Experience working with ODM and OEM suppliers
  • Programming experience in test/measurement automation and/or simulation
