Software Engineer - Virtualization & Management of Storage (VaMoS)

Join our Virtualization & Management of Storage team to work on fundamental infrastructure that powers every Apple device. We're seeking an exceptional system engineer to design and implement critical storage frameworks spanning disk management, unified storage APIs, and virtualized storage solutions across macOS, iOS, and other Apple platforms. You'll work on low-level system components that directly impact performance, reliability, and user experience for millions of devices. Our environment champions product innovation, deep technical exploration, and meaningful autonomy.

Description
You'll develop and enhance frameworks that handle disk image operations, provide unified storage abstractions, and enable cutting-edge virtualization technologies. This role requires both breadth and depth, comfortable working from kernel-level drivers to user-space frameworks, debugging complex multi-layered systems, and collaborating across hardware, kernel, and application teams. You'll participate in all phases of development: architecture, implementation, optimization, testing, and integration with deeply integrated platform features.","responsibilities":"Develop kernel-level storage components and user-space frameworks for macOS and other Apple platforms
