Signal Integrity Engineer, Infrastructure Hardware
Meta PlatformsJob Title
Signal Integrity Engineer, Infrastructure Hardware
Role Summary
Join Meta's infrastructure hardware team to design and validate high-speed interconnects for data-center AI, networking, and compute platforms. Perform signal integrity design, simulation, and lab validation to ensure reliable high-speed data transmission across Ethernet, PCIe, DDR, and optical interfaces.
Collaborate with hardware design teams, ASIC partners, and vendors to influence platform architecture and deliver scalable infrastructure.
Experience Level
Entry-level / Early-career - 2+ years of relevant signal integrity or high-speed digital systems experience.
Responsibilities
Primary responsibilities include design, analysis, and validation of board- and system-level high-speed channels:
- Perform signal integrity simulations and validation using 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 end-to-end electrical–optical–electrical channels.
- 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 (TDR, VNA, oscilloscope) 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.
Requirements
Must-have:
- 2+ years of experience in signal integrity engineering for high-speed digital systems, including board-level and system-level SI/PI analysis.
- Programming experience in test/measurement automation and/or simulation.
Nice-to-have:
- Experience with PCB board-level design, layout, and validation.
- Experience with SerDes bring-up, equalization tuning, and compliance testing for new interface standards.
- Experience with advanced PCB/HDI materials and evolving interconnect technologies.
- Familiarity with IBIS-AMI modeling, channel simulation automation scripting, and statistical eye analysis methodologies.
- Experience with lab correlation and validation activities (TDR, VNA, oscilloscope) to verify simulation accuracy.
Education Requirements
Bachelor's degree in Electrical Engineering, Computer Science, Computer Engineering, or a related technical field, or equivalent practical experience.
