10+ years of work experience in machine learning infrastructure, distributed data systems, or a related field
10+ years of experience building and shipping large-scale data or ML infrastructure and platforms in production
Extensive experience architecting and delivering large-scale distributed data or ML infrastructure that multiple teams or products depend on in production

About the role
Join a team at the forefront of ML infrastructure and generative AI, where data and model workflows come together to enable the next generation of intelligent experiences on Apple products and services. We build robust systems that connect scalable data pipelines with advanced ML workflows, accelerating the development of real-world AI applications. Our work spans the full ML lifecycle, from experimentation to deployment, and you’ll play a key role in shaping how AI models are built, optimized, and scaled. We develop a platform for ML data and features that powers advanced GenAI applications. This includes embeddings (generation, evaluation, ANN search, multimodal support), AI Ops, efficient inference, and a modern feature platform designed to streamline experimentation and drive innovation. We’re looking for engineers and researchers passionate about generative models, data-centric ML, and intelligent systems across diverse real-world use cases. With the autonomy to experiment, the scale to make an impact, and the support to take ideas from prototype to production, you’ll work alongside a world-class team to build intelligent, flexible systems that make ML development faster, more reliable, and more creative.
Description
The Apple AI Platform team gives Apple’s ML engineers and researchers the data systems and large-scale compute they need to build and ship models at Apple’s bar for quality and privacy. Our team owns the data layer that large-scale model training depends on: ingestion, versioning, lineage, and governance on the way in, and high-throughput data loading into the training fleet on the way out. As a Staff ML Infrastructure Engineer, you will set the technical direction for that platform and own its hardest system-level problems, the architecture other engineers and teams build on.
Responsibilities
•
Own the architecture of the platform behind Apple’s largest model builds: define how ingestion, immutable versioning, lineage, and governance work across structured, unstructured, and multimodal data at petabyte scale, so every model run is reproducible from a versioned dataset.
•
Set the technical direction for high-throughput data delivery to Apple’s largest GPU and TPU fleets: define the data access and loading architecture that keeps training compute-bound, not I/O-bound.
•
Make the hard system-level and format calls that the whole platform inherits, columnar and lakehouse strategy, the dataset abstraction spanning structured and multimodal data, the shape of the SDK and core libraries, backed by design and proof, not just opinion.
•
Drive technical direction and influence across the platform and partner teams (data, embeddings, features, research), and define the interfaces and contracts between them.
•
Raise the technical bar across the team: mentor senior engineers, lead design reviews, and be the escalation point for the problems no one else can crack.
•
Partner with research and product leadership to shape the platform roadmap for next-generation workloads: foundation models, multimodal data, and retrieval-augmented systems.
•
Drive efficiency, reliability, and automation across the data plane and control plane that power Apple’s ML fleet.
