The iOS playback team designs, implements and maintains high-performance software that powers video playback on millions of iOS devices. We are responsible for the playback experience, quality and performance from the time you press play on an Amazon Video title. Our software is designed to work seamlessly on a variety of devices, in a variety of playing conditions and in a multitude of content consumption contexts including live streaming, on-demand and ad-supported playback. We obsess over the time that elapses between pressing play to when the first frame is rendered to the screen. We are constantly refreshing our software and adding new functionality that allow users to get the best out of both the Amazon video library and their specific device. We respond to organizational and competitive needs and build high-quality software fast in an agile development environment. We work closely with other Amazon software teams and help them build video functionality into their offerings.
