About the Role
At Apple, we believe innovation flourishes when diverse minds come together, challenging ideas, encouraging collaboration, and pushing technology to its limits. Join us and help make the world a better place. As a Site Reliability Engineer (SRE) on our team, you will own the reliability, performance, and scale of the distributed storage and data platform systems powering Apple’s services. You will debug replication and consensus failures, tune systems at petabyte scale, and write production code that operates the platform. We embrace ownership, with software engineers accountable for the code they write.

The Apple Services Engineering (ASE) organisation builds and provides the systems and infrastructure that fuel Apple’s services such as iCloud, iTunes, Siri, and Maps. Our team builds and operates the data platform infrastructure behind these services, maintaining petabyte-scale workloads that are fast, resilient, and reliable.

The platform runs on large-scale distributed systems including object stores, databases, and data pipelines on Linux across private and hybrid cloud environments. You will work on storage engines, distributed consensus, and data-flow internals, partnering with development teams on system-wide architecture rather than individual components.

Experience
- Managing and scaling large-scale distributed systems in private or hybrid cloud environments
- Designing, writing, and releasing production code in languages such as Go or Python
- Debugging and reasoning about failures and performance in distributed systems at scale
- Contributions to distributed-systems internals, open-source data infrastructure, or storage/database engines
- Defining SLIs/SLOs, building observability, and using error budgets to drive reliability decisions
- Strong grasp of Unix internals and networking fundamentals
- Experience with data migration, disaster recovery, or capacity planning at scale
- Willingness to participate in on-call rotations and incident response to maintain critical system health

About you
You are passionate about building reliable, scalable systems and thrive in a collaborative environment. You take ownership of your work and are motivated by solving complex problems at scale. You communicate effectively and work well with cross-functional teams to design and operate critical infrastructure.

Qualifications
Relevant experience in site reliability engineering, distributed systems, or software engineering roles is expected. Formal qualifications are valued but not mandatory; a strong technical background and proven track record are essential.
