Multimodal Machine Learning Engineer, Global Siri
The Global Product Experience team creates groundbreaking user experiences across Siri markets. The features we build are redefining how hundreds of millions of people across all Siri languages are connected to the information they are looking for and the apps they love to use through various devices. As part of this group, you will work in one of the most exciting environments with state-of-the-art machine learning (ML) and AI models applied to production problems. We build machine learning (ML) technologies that scale to all Siri languages. You will have the opportunity to innovate with large-scale AI models to help Siri better understand and converse in different languages.
In Global Siri, we are responsible for the end-to-end user experience in all Siri markets. This means we build new features and scale them across Siri languages and devices. As an ML engineer in Global Siri, you will help us build and apply ML solutions to scale new features across different languages and modalities. You should be able to work with large scale systems, write high quality code, work effectively with agentic AI tools, and be comfortable in contributing to existing systems and developing new ones. A collaborative and communicative attitude is required to coordinate work across multiple teams.
