This position will form part of the leadership team incubating and delivering the future of Siri in Apple. You will operate within a large, multi-functional ecosystem spanning partners in Siri, AIML technology and infrastructure teams, data, research, and software engineering, and also work with teams in hardware products and silicon. You will lead core areas of the product, partner with numerous directors and director-level engineers, report on progress directly to executives, and be given considerable latitude to determine where to focus your energy. You will balance between developing portions of the product yourself where there is high uncertainty or risk, and guiding teams of engineers where you have made the path more clear. You will become a mentor to large numbers of more junior engineers, and help set the standard for engineering practices.
