The Global Product Experience team creates groundbreaking user experiences across Siri markets using natural language processing (NLP) and machine learning (ML). As part of this group, you will work in one of the most exciting environments with state‐of‐the‐art ML and NLP models applied to production problems. You will have the opportunity to innovate with multilingual NLP models to help Siri understand different languages and user queries better! In Global Siri, we are responsible for the end‐to‐end user experience in all Siri markets. You should be able to work with large‐scale systems, write high quality code and be comfortable contributing to existing systems and developing new ones.
