Mid Level ML Software Engineer Jobs

Imagine what you could do here. At Apple, great ideas have a way of becoming phenomenal products, services, and customer experiences very quickly. Bring passion and dedication to your job and there's no telling what you could accomplish.

Do you love solving complex distributed systems challenges at massive scale? Are you passionate about Kubernetes scheduling, resource management, and building platforms that power the next generation of Machine Learning and Data workloads? Do you thrive in designing and operating highly reliable, large-scale job scheduling and orchestration systems that serve as the backbone of AI and Data infrastructure? If so, join the Apple Data Platform team to design and build a scalable batch and ML infrastructure platform used across Apple.

As part of Apple Data Platform, you will play a meaningful role in designing, developing, and deploying high-performance systems that power batch and ML workloads across Apple's global infrastructure spanning public clouds and Apple data centers. This enormous scale brings unique and complex challenges in resource scheduling, workload orchestration, and operational excellence that require extraordinarily creative problem-solving.

Description

Apple Batch is a fully managed platform within the Apple Data Platform that supports large-scale batch and ML workloads across Apple data centers and AWS/GCP. It orchestrates containerized workloads such as Spark, Ray, and LLM batch inference using YuniKorn/Kueue for advanced multi-cluster scheduling. The platform delivers org/team quota management, automatic node repair, end-to-end observability, strong security, and granular cost reporting.

As part of the Apple Batch team, you will have a meaningful role in designing, developing, and deploying high-performance systems that power large-scale batch processing and ML workloads daily. We are building critical infrastructure that provides scalable batch execution, intelligent Kubernetes-native job scheduling, multi-tenant resource management, and efficient workload orchestration for ML training, inference, and data processing workloads across multi-cloud and on-premises environments.

We are looking for a strong, enthusiastic engineer with deep expertise in Kubernetes scheduling and distributed systems. You will have significant individual responsibility and influence over critical platform services. You are someone with ideas and a real passion for building infrastructure that improves reliability, efficiency, and simplicity at Apple scale.
