ML Researcher, Apple Foundation Models

Job description

We build frontier foundation models that power intelligent experiences at Apple.

Our team works across the full training lifecycle

including pre-training foundation models, and developing mid-training approaches that bridge general capability and task-specific performance. What makes our work distinct is that we're engineering models specifically for Apple silicon and optimized for experiences that are private, personal, and deeply integrated into the OS. We're solving frontier problems in reward modeling to resist reward hacking, handling sparse and delayed rewards in agentic settings, and aligning models reliably across the spectrum from open-ended creative tasks to precise, action-taking workflows.

If you're drawn to hard problems where the research and the product are inseparable, this is the team
