Imagine what we could do 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 telling what we could accomplish. Apple is looking for an experienced Software Engineer to help develop the next generation of cloud services infrastructure. You will be working on key components of the iCloud platform and introducing new fundamental capabilities. Your work will help to power entirely new applications and scale existing ones, such as FaceTime, PushNotifications, iCloud Drive, Photos, and Backup. This is your chance to put a dent in the Universe. You will work with elite teams who have a real passion for engineering and delivering features that maintain strong privacy guarantees to end users.

Description

We work on the client-side of iCloud services, building the foundations for a secure and private cloud from device to device encrypted storage in the cloud to protected computation. Apple's commitment to privacy runs deep and this team is key to extending this commitment to the cloud.

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 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 building on Apple Platforms (macOS, iOS, watchOS, tvOS, etc.)

• Experience designing and building developer-facing APIs is a plus

• Experience with Event-based programming or inter-process communication is a plus

Minimum Qualifications

5+ years of software engineering experience with strong programming skills in Objective-C, C, Swift, or C++

Experience with security, privacy, and cryptography concepts

Proven track record of working on rapid development cycles and shipping software on tight schedules
