Lead Distributed Systems Engineer Services Special Projects

Apples Special Services Team is seeking a Lead (Principal) Distributed Systems Engineer to design and build massively scalable highly available services that power experiences for Apple customers both now and in the future. n

In this Lead role you will build and operate high-throughput low-latency backend services that ingest process and serve data at scale across a range of mission-critical workloads from real-time transactions to analytics and content delivery. Youll also drive the evolution of a multi-tenant platform including AI/ML-powered services by shipping new capabilities scaling what exists and applying distributed-systems best practices from design through production.

Lead the design and building of new features and services with a focus on scalability responsiveness fault tolerance and high large-scale backend services that are resilient to failures without breaking downstream the partnership with other Apple teams to ensure we ship customer-facing features which are performant well-modeled service the lead technical guide and mentor for this growing team fostering a positive culture of learning growth and innovation. nLead high-level discussions across Apples ecosystem
