As a Machine Learning Engineer on our team, you will enable next-generation AI applications by building toolkits and workflows that scale to increasingly sophisticated modeling tasks. You will design the abstractions and implement the algorithms that facilitate efficient data synthesis, data curation, prompt engineering, and model evaluation. You will contribute to a company-wide effort to build robust modeling pipelines that optimize our ability to iterate rapidly and continuously deliver improvements to our customers. Finally, you will help define and refine new features that expand both the depth of Apple Intelligence’s capabilities and the breadth of its support for the full spectrum of Apple customers.Key responsibilities:* Development and maintenance of data and model pipelines that scale to deployment in production* Building toolkits for iterating on model quality via data synthesis and prompt engineering* Definition of robust automated evaluation mechanisms to facilitate hillclimbing on model quality* Failure analysis from user feedback to understand shortcomings of our models and evaluation data* Research into state-of-the-art techniques for improving model quality and robustness* Implementation of experiments and simulations to assess the value of model changes
