You will work closely with Design, taking ideas, use cases, and specifications from early prototype through a world class shipped product, pushing the UI experience to its limit., * Turn design specifications, use cases, and rough ideas into shipping interfaces, from early prototype through production on real hardware * Own execution: take a prototype the whole way to something that ships, with the quality bar held at each step * Find where the design language outruns the platform, and push the UI software at every layer needed to close the distance * Advise designers on what the system is actually capable of, early enough for it to change the design * Shape the UI runtime and system architecture with requirements drawn from real designs rather than hypotheticals * Own the end-to-end development of user experiences alongside design, firmware, and hardware partners
