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.
