Staff iOS Software Engineer - CloudKit

Imagine what we could create together! At Apple, new 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 limit to what we could accomplish.

Apple is seeking an experienced Staff Software Engineer to contribute to the development of the next generation of cloud services infrastructure. You will be responsible for designing and implementing key components of the iCloud platform, integrating novel fundamental capabilities deeply into the core of Apple's operating systems. Your work will enable the creation of entirely new applications and the scaling of existing ones, including FaceTime, Push Notifications, iCloud Drive, Photos, and Backup. This is an opportunity to make a significant impact. You will collaborate with highly skilled teams dedicated to engineering excellence and deliver features that uphold strong privacy guarantees for end users.

Description

On the client-side of iCloud services, our team is responsible for establishing the foundations of a secure and private cloud. This includes device-to-device encrypted storage in the cloud, protected computation, and other essential components. Apple's commitment to privacy is deeply ingrained in our work, and this team is instrumental in extending this commitment to the cloud.

This position requires close collaboration with the CloudKit team, as well as with several other teams working on server components and Apple's Cryptography and Privacy teams. The role entails both low-level (C/Objective C, libdispatch, POSIX APIs) and system-level skills (synchronization protocols, framework design, IPCs, multi-process performance work, system-wide resource sharing). Reliability is paramount, and we seek engineers with a genuine passion for constructing complex systems that can seamlessly recover from errors.

As part of this role, you will:

• Work with adopters to craft clear APIs

• Work with the network and file system stacks to build performant system daemons

• Work with our server counterparts to design scalable features and protocols

• Implement core components of the cryptographic protection of cloud data

Preferred Qualifications

Experience with Swift concurrency

Experience with security, privacy, and cryptography concepts

Experience with event-based programming and/or inter-process communication is a plus
