Summary:

Meta services (Instagram, Facebook, Whatsapp and others) are used by billions of people daily relying on Mobile and Fixed (including Wi-Fi) networks. At Meta, we invest to sustainably build and improve state of the art network infrastructure to connect our data centers and POPs with the rest of the Internet and to make the connectivity ecosystem more reliable and efficient. The unique challenge is to deliver the best quality of experience for consumers of Meta’s multi-media products while ensuring efficient usage of Meta’s and CSP’s network resources. As a Communications Systems Engineer, you will work closely with the Meta Network Infra team, contractors, cross-functional partners, vendors, and partners across industry to improve efficiency, reliability, and overall QoE of Meta products and services across CSP networks. The team is responsible for addressing issues across technical domains including video services, real-time communication, upcoming AR/VR experiences, cellular radio, Wi-Fi, fixed access, IP transport, fixed and mobile core, cloud services, APIs, and analytics. As a member of this team, you will develop solutions to complex communication system problems and be involved in all project phases spanning initial design, simulation and prototyping, validation and characterization, and on-going optimization based on measurements and learnings from the lab and production services. You will need to be hands-on in the lab to be successful in this role. Success ultimately results in improving the daily experience of billions of users around the world.
