About The Position

The Global Device Operations team designs, builds, and manages a network of large-scale device farms across multiple global data centers. These device farms contain thousands of consumer-grade connected devices — including set-top boxes, smart TVs, mobile phones, gaming consoles, and more — which power testing and quality assurance for WBD’s global streaming platforms. This team owns and operates the network and infrastructure that makes these environments performant, secure, and scalable. From routing design to tunnel-based geolocation, from overlay networks to automation, we operate at the crossroads of engineering, operations, and innovation.
