## Description

As a Senior/Staff Engineer on the Foundation Model Compute Infrastructure team, you will design and build large-scale infrastructure that powers foundation model training, fine-tuning, evaluation, and inference. You will develop model inference and fine-tuning services, onboard and benchmark new accelerators, and work closely with foundation model researchers and engineers to improve reliability, performance, scalability, and developer productivity across Apple's AI workloads.

Responsibilities:

Design, build, and evolve large-scale model serving and fine-tuning services for foundation model workloads

Develop reliable infrastructure for model deployment, serving autoscaling, traffic management, job execution, container orchestration, and serving performance analysis

Improve the performance and usability of model serving and fine-tuning workloads by optimizing latency, throughput, availability, accelerator utilization, checkpoint loading, compilation caching, KV-cache-aware routing, and workflows for launching, monitoring, debugging, evaluating, and deploying models

Onboard and Benchmark new accelerator technologies into Apple's compute infrastructure

Collaborate with the Apple Foundation Model team to integrate technologies such as Pathways, Ray, and Beam, or expose them as reliable and scalable services

Mentor engineers and partner across teams to influence the technical direction of Apple's foundation model compute infrastructure
