AIML - Machine Learning Engineer, Foundation Models

Apple • Cupertino, CA

23h • Onsite

About The Position

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. We believe that the most interesting problems in deep learning research arise when we try to apply learning to real-world use cases, and this is also where the most important breakthroughs come from. You will work with a close-knit and fast growing team of world-class engineers and scientists to tackle some of the most challenging problems in foundation models and deep learning, including natural language processing, multi-modal understanding, and combining learning with knowledge. Further, you will have opportunities to identify and develop novel applications of deep learning in Apple products. You will see your ideas not only published in papers, but also improve the experience of millions of users.

Requirements

• Proven track record in training or deployment of large models or building large-scale distributed systems.
• Proficient programming skills in Python and one of the deep learning toolkits such as JAX, PyTorch, or Tensorflow.
• Ability to work in a collaborative environment.
• PhD, or equivalent practical experience, in Computer Science, or related technical field.

Nice To Haves

• Web-scale information retrieval
• Human-like conversation agent
• Multi-modal perception for existing products and future hardware platforms
• On-device intelligence and learning with strong privacy protections
