As a Machine Learning Engineer, you will be responsible for developing and applying machine learning techniques to improve Siri's ability to understand and respond to user queries in real-time. You will work on a variety of tasks including: • Designing, developing, and implementing machine learning models to power Siri invocation features. This will involve data analysis, experimentation, and modeling to create user journeys that are seamless and intuitive. • Conducting experiments to evaluate the performance of machine learning models and identify areas for improvement • Conducting error estimation and monitoring distribution shifts to ensure model performance and robustness. • Collaborating with cross-functional teams to productionize next generation of machine learning models for Siri invocation • Staying up-to-date on the latest advances in machine learning and applying them to Siri's development
