Sr. / Staff ML Engineer, FM Training Integration - ML Compute

We are a group of engineers to support training foundation models at Apple! We build infrastructure to support training foundation models with general capabilities such as understanding and generation of text, images, speech, videos, and other modalities and apply these models to Apple products. We are looking for engineers who are passionate about building systems that push the frontier of deep learning in terms of scaling, efficiency, and flexibility and delight millions of users in Apple products.

Description

We are looking for a ML Engineer to join our ML Compute team to help improve the efficiency, scalability, and reliability of model training and inference workloads in the cloud. In this role, you will lead the integration of large-scale ML workloads with cloud infrastructure, working cross-functionally with ML engineers, infrastructure engineers, and researchers to optimize performance, improve system efficiency, and drive high utilization of accelerator resources.","responsibilities":"Own the integration of large-scale model training workloads with accelerator-based cloud infrastructure, ensuring scalable and reliable execution.

Drive performance optimization across the ML stack, including data pipelines, model execution, and distributed systems, to improve throughput, latency, and hardware utilization.

Design and run benchmarks to evaluate model performance and infrastructure configurations, using results to guide optimization efforts.

Build and improve tooling for observability, profiling, and debugging to increase visibility and reliability of ML workloads.

Collaborate cross-functionally with ML engineers, infrastructure engineers, and researchers to improve system efficiency and scalability.

Establish and promote best practices for performance tuning and resource utilization.

Drive high-quality design and code reviews, share best practices, and elevate engineering standards across the team.

Preferred Qualifications

Experience working with accelerator-based systems (e.g., GPUs/TPUs), including performance tuning and debugging of ML workloads.

Hands-on experience with distributed training or inference at scale (e.g., data, model, or pipeline parallelism).
