About the role

What will you do at Apple?

Do you want to help build some of the largest and most consequential enterprise

and customer technology systems in the world? Join Apple’s Information Systems

and Technology (IS&T) organization. IS&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.” Do you love

building solutions to handle global complexity and immense scale? Imagine what

you could do here. Infrastructure 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.

DESCRIPTION

We 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. If 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.
MINIMUM QUALIFICATIONS
Strong proficiency in systems programming languages such as C++, Go, or C
(experience with Java or modern scripting languages like Python is also valued).
Solid foundation in Computer Science fundamentals: advanced data structures,
algorithms, memory management, and concurrency. Deep 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. Experience with source control (Git) and modern build/configuration
management tools. Experience designing and optimizing scalable network data
plane components, packet forwarding paths, or kernel/userspace networking
subsystems. Understanding of microservice architectures, asynchronous
communication, and API design (REST, gRPC, Protobuf). Proven ability to analyze
and debug complex live production incidents under pressure using metrics,
traces, and system logs. Strong communication and cross-functional collaboration
skills with the drive to take ownership and lead projects to closure.
PREFERRED QUALIFICATIONS
8+ years experience with kernel-bypass/accelerated packet processing
technologies (e.g., DPDK, XDP, eBPF, VPP, OVS or P4). BS or MS in Computer
Science or equivalent experience. Familiarity with hardware offload
architectures (SmartNICs, ASICs) and network virtualization. Hands-on experience
developing large-scale distributed cloud infrastructure services.
