Senior Engineer - System Scheduling Performance

Allocating resource usage efficiently is a key differentiator for Apple products. The System Scheduling Performance team focuses on solving these tough resource tradeoffs by developing the technology for a background task scheduler that runs on every one of our platforms. Part of CoreOS, this team is at the intersection of power, performance, and feature latency. We look to schedule workloads intelligently in optimal device conditions, considering feature usage history, battery life, thermals, network efficiency, memory, and more. This technology is at the foundation of features such as Apple Intelligence, Photo Processing, Spotlight Search, Automatic Software Updates, CloudKit Sync, Background App Refresh, iCloud Photo Library, and many more! The team is looking for innovative candidates to design and implement new capabilities to manage process runtime and resource utilization across our diverse product lines. In this highly visible role, you will be driving the development of a scalable architecture for resource management, as well as influencing and assisting cross-functional teams with the adoption of these new operating system concepts. Through the combination of effective collaboration, data and performance analysis, software prototyping, and systems engineering, you will push the boundary of what's possible at the core of the operating system!

Description We're looking for a highly motivated systems software engineer with excellent analytics, problem solving and communication skills to design a scalable scheduling system to handle the ever increasing demand for background processing as well as contribute high-quality software to iOS, iPadOS, macOS, watchOS, visionOS, tvOS and more.
