Job description

Summary

The Apple Services Engineering (ASE) team is one of the most exciting examples of Apple’s long-held passion for combining art and technology. These are the people who power the App Store, Apple TV, Apple Music, Apple Podcasts, and Apple Books. And they do it on a massive scale, meeting Apple’s high expectations with high performance to deliver a huge variety of entertainment in over 35 languages to more than 150 countries. These engineers build secure, end-to-end solutions. They develop the custom software used to process all the creative work, the tools that providers use to deliver that media, all the server-side systems, and the APIs for many Apple services.

Thanks to Apple’s unique integration of hardware, software, and services, engineers here partner to get behind a single unified vision. That vision always includes a deep commitment to strengthening Apple’s privacy policy, one of Apple’s core values. Although services are a bigger part of Apple’s business than ever before, these teams remain small, forward-thinking, and cross-functional, offering greater exposure to the array of opportunities here.

• Participate in code reviews and provide helpful and precise feedback
• Constantly evaluate and improve our own delivery processes within the team
• Evolve critical, foundational systems to provide next generation features at scale

Minimum Qualifications

• Advanced experience with programming languages (Go, Python, Ruby, Bash) and a passion for designing and building reliable systems
• Strong sense of ownership and integrity demonstrated through clear communication and collaboration with a deep systems and infrastructure knowledge
