Cambridgeshire, United Kingdom
Machine Learning and AI


Role Number: 200007465
"People with passion can change the world" The launch of Siri was a defining moment in the history of Artificial Intelligence. Hundreds of millions of people now use Siri to send a message, play their favourite song or even take a selfie. Now imagine what you could do here at Apple? At Apple we're driving a new revolution in the way people and machines interact. We are looking for a creative Senior Applied Scientist to own the development of new algorithms for implementing conversational dialogue with the overall goal of making Siri more intelligent.

Key Qualifications

  • NLP applications and/or conversational dialogue systems
  • Machine learning fundamentals
  • Software engineering skills
  • Large-scale machine learned systems
  • Publications in top-tier NLP and/or machine-learning conferences
  • Leading projects and/or building research agendas
  • Experience in mentoring junior colleagues


Working as part of an extraordinary team, including world renowned academics, top software engineers and expert machine learning practitioners, we are passionate about applying groundbreaking techniques to conversational dialogue. Siri processes more than a billion requests every week, so you will enjoy implementing machine learning at scale and you'll take on all the complexities involved in taking research work through to production. You will love the state of the art resources at Apple. Huge compute grids, top-quality machine learning tools, and large quantities of data will help you improve user facing features. Day to day you will be leading the development of new NLP components and prototyping solutions within the Siri system. You will provide technical leadership as well as direct hands-on contributions to model design, evaluation and reporting of scientific results. If you are interested in taking on line management responsibilities, there will be opportunities to do so. However you contribute, our goal is to make a real difference to the lives of Siri users. There are many difficult problems for us to solve, so we're keen to take on new ideas and ways of thinking. If this is you, we'd love to hear from you.
