Join Apple’s Information Systems and Technology (IS&T) organization.\nIS&T is the engine behind everything Apple does for customers and for the people who build for them. It’s Apple’s central nervous system. Supporting 2.5 billion active Apple devices, processing billions of secure transactions, and keeping the technology that defines modern life running flawlessly, IS&T makes the impossible feel effortless.”\nDo you love building solutions to handle global complexity and immense scale? Imagine what you could do here.\nInfrastructure Services is part of IS&T and the foundation of Apple's global network operations - managing data center equipment and systems to deliver compute, storage, and networking services for teams across Apple, including its internal developer community. From individual facilities to a worldwide network, Infrastructure Services ensures the technology underneath everything works without question.\nDescription\nWe are looking for passionate engineers who love building super-scalable, reliable, and high-performance systems to support one of the world’s largest cloud infrastructures. In this role, you will design, build, and operate next-generation services that power virtualized networks, computing, and storage. Operating at our global scale presents unique challenges that demand radical engineering innovations.\nIf you are excited about working close to the packet, optimizing line-rate forwarding pipelines from scratch, and solving complex distributed systems problems, our team is the place for you.\nMinimum Qualifications\nStrong proficiency in systems programming languages such as C++, Go, or C (experience with Java or modern scripting languages like Python is also valued).\nSolid foundation in Computer Science fundamentals: advanced data structures, algorithms, memory management, and concurrency.\nDeep knowledge of Networking Fundamentals & Dataplane internals: L2-L4 protocols, TCP/IP stack behavior, packet framing/encapsulation, routing, MTU/MSS, flow tables, and QoS/traffic shaping.\nExperience with source control (Git) and modern build/configuration management tools.\nExperience designing and optimizing scalable network data plane components, packet forwarding paths, or kernel/userspace networking subsystems.\nUnderstanding of microservice architectures, asynchronous communication, and API design (REST, gRPC, Protobuf).\nProven ability to analyze and debug complex live production incidents under pressure using metrics, traces, and system logs.\nStrong communication and cross-functional collaboration skills with the drive to take ownership and lead projects to closure.\nPreferred Qualifications\n8+ years experience with kernel-bypass/accelerated packet processing technologies (e.g., DPDK, XDP, eBPF, VPP, OVS or P4).\nBS or MS in Computer Science or equivalent experience.\nFamiliarity with hardware offload architectures (SmartNICs, ASICs) and network virtualization.\nHands-on experience developing large-scale distributed cloud infrastructure services.","description_format":"text","description_chars":3135,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Operating
