Machine Learning Research Engineer, Input Experience - NLP

Our team's mission is to enhance ML powered user experiences on all Apple platforms through personalized multimodal input, composition, and understanding, with a global perspective. We achieve this daily by collaborating at the intersection of natural language processing, machine learning, and software engineering.

We are responsible for the machine learning and software (non-UI) development for several user-facing Apple Intelligence features, including Writing Tools, Summarization, Found In Apps, and Messages/Mail Smart Replies. Additionally, we oversee the keyboard machine learning and software stack, which includes autocorrection, suggestions, and inline completions.

If you're passionate about being part of an ambitious, organized, and collaborative team that delivers user experiences with pioneering ML partnered with the best UI designs, join the Input Experience NLP team. Here, you'll have the opportunity to transition from building groundbreaking NLP models to optimizing them for various hardware backends and user interfaces that create an enchanting experience.

Description

As a Machine Learning Research Engineer on our team, you'll build and iteratively refine model pipelines that enable machine learning driven user experiences on Apple products. You'll conduct experiments and create prototypes for innovative approaches to enhance the quality of our models and expand their intelligence. Additionally, you'll implement the building blocks and infrastructure that integrate these innovations into our production pipelines and contribute evaluation metrics to measure progress.","responsibilities":"Building models for new user interface experiences.
