Signal Integrity / Power Integrity Engineer

Signal Integrity and Power Integrity (SIPI) Engineers at Meta design, analyze, and validate SIPI aspects of electrical systems for next-generation hardware products and platforms. They collaborate with multidisciplinary teams and external partners to deliver robust, high-performance solutions from concept through deployment, ensuring Meta’s hardware meets the highest standards for performance, reliability, and electromagnetic compatibility across both product and infrastructure domains.

In this high-impact role, you will lead system-level SI/PI design, simulation, and validation efforts—transforming concepts into industry-leading products. Your expertise will directly influence every stage of the design process, from simulation and automation development to hands-on lab validation, ensuring our devices set new standards for electromagnetic compatibility and performance.

Responsibilities

• Perform Signal Integrity analysis, collaborating with different engineering teams to balance system/product constraints with MIPI CPHY, DPHY, MPHY, PCIE, USB and high speed clocks.
• Perform pre-layout and post-layout simulation flow with a focus on PDN.
• Create simulation models and develop simulation methodology for SIPI design.
• Stackup review and layer assignment for High speed and PDN.
• Lead SIPI validation methodology and develop detailed engineering test plans.
• Validate PDN impedance in lab to correlate simulation results and improve design flow.
• Use simulation and lab data to support design troubleshooting and propose corrective actions, drive failure analysis, root cause efforts, and design of experiments to resolve problems.
• Analyze chip/package/PCB PDNs and make design trade-offs and negotiate power budgets.
• Provide design specifications and guidelines with clear risk tradeoffs to our cross-functional partners.
• Explore various design elements including different sensors, modules, memories, low/high speed buses, cables, connectors, flexible and rigid PCBs (FLEX), their physics of operation, and impacts on system performance.
• Provide system SI design guidance and perform post-layout review and optimization.
• Work closely with silicon team, EE design team and PCB layout team to optimize SI design based on the simulation data;.
• Use simulation and lab data to support design troubleshooting and propose corrective actions, drive failure analysis, root cause efforts, and design of experiments to resolve problems.
• Generate simulation reports based on the data and communicate with Cross-functional teams with clear SI recommendations.
