Senior Machine Learning Engineer

Join a passionate, dynamic team responsible for creating experiences that enable users to get help with-and discover all the things they love about-their Apple products. In this role, you will have the opportunity to join a team building applications, frameworks, and system-level experiences for hundreds of millions of users across the Apple ecosystem. The Instructional Products team is looking for a Senior Machine Learning Engineer to join a team building both internal and customer-facing features, applications, and tools. In this role, you'll be at the forefront of shaping personalized help and discovery experiences powered by state-of-the-art machine learning, generative AI, and agentic systems and modeling.

Description As a Senior Machine Learning Engineer, you will guide the end-to-end delivery of multiple ML and generative AI initiatives. Your work will span defining technical strategy, shaping data pipelines, building and deploying models, and iterating post-launch. You will partner closely with product, design, engineering, and content teams to create features that are contextually aware and deeply aligned with Apple's user experience principles. You'll contribute to the development of LLM-powered systems, including prompt engineering, fine-tuning on domain-specific data, and Retrieval-Augmented Generation (RAG) architectures. Experience with agent-based systems-such as multi-step reasoning, tool use, and task planning-is highly valued. Your success in this role will depend on a strong understanding of how users interact with Apple's products, and on your ability to translate ML innovations into intuitive, intelligent experiences that scale.
