This paper presents an overview of the User Experience (UX) team at Google. We focus on four aspects of working within Google's product development organization: (1) a bottom-up 'ideas' culture, (2) a data-driven engineering approach, (3) a fast, highly iterative web development cycle, and (4) a global product perspective of designing for multiple countries. Each aspect leads to challenges and opportunities for the UX team. We discuss these, and outline some of the methodological approaches we employ to deal with them, along with some examples of our work.
