LLM Machine Learning Engineer, Models and Agent Science, AIML
The Apple Intelligence Agents, Infrastructure, and Research team brings innovative AI research into Apple products, with a focus on optimizing, interpreting, and developing new algorithms for on-device and server-based Apple Foundation Models and Apple Intelligence features.
Description
We are looking for talented Machine Learning Applied Scientists and Research Engineers to build groundbreaking machine learning capabilities and drive emerging innovations. You will join a collaborative team of software developers and deep learning experts focused on large language modeling, optimization, interpretability, and related algorithms. In this role, you will drive applied innovation and evaluate emerging research for real-world viability, translating promising ideas into the Apple product context. You'll bridge the gap between cutting-edge ideas and the constraints of shipping AI at scale.
Successful candidates will bring a strong software engineering background, hands-on zero-to-one machine learning development experience, and broad expertise in post-training machine learning models (including quality and performance optimization).
Preferred Qualifications
PhD in a related field
Publication record at top AI/ML venues
Experience with post-training LLMs and network optimization algorithms, as well as interpretability or steering techniques for LLMs
Experience of working with large-scale compute infrastructure
Experience shipping a real world product, project or feature
Experimental rigor and ablation design when benchmarking LLM optimizations
