Job Description

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.

We’re looking for passionate folks who love building super-scalable, reliable, and user-friendly systems to support one of the world’s biggest cloud infrastructures. You’ll be designing, building, and running new services that help lead virtualized networks, computing, and storage. Working at our global scale brings some unique and tough challenges that require us to come up with radical innovations. These services are built using skills from different areas, like distributed systems, user experience, and modular and resilient programming. If you’re excited about innovating and building systems from scratch for the massive scale of our infrastructure, then our team might be the perfect place for you!

Preferred Qualifications

Broad experience in designing and developing RESTful APIs and micro-services architectures.
Hands-on experience managing cloud provider networking resources programmatically via APIs/
SDKs in at least one major cloud environment (AWS, GCP).
Proven experience defining the automation strategy, infrastructure-as-code paradigms
(Terraform/OpenTofu), and continuous deployment pipelines (ArgoCD, GitLab CI) for complex
cloud environments.
Experience working with Linux network virtualization constructs (network namespaces, iptables/nftables, eBPF, routing tables), or developing custom network virtual appliances.
Experience in OVS, Container & Kube networking

Minimum Qualifications

10 years of hands-on experience in software development, with at least 4+ years focused on building highly scalable distributed control planes, cloud orchestration engines or software-defined networking (SDN) controllers

DNS implementations. Strong understanding of traffic steering, policy-based routing, and stateful connection tracking.
Strong proficiency in GoLang, C, or Python, with a willingness to work primarily in GoLang.
A solid understanding of concurrency patterns and writing high-performance code.
Demonstrated leadership in driving cross-functional technical alignment, breaking down
complex multi-cloud networking requirements, and fostering a culture of rigorous design and
code quality.
Proven track record of root-causing complex networking anomalies (split-brain scenarios, packet drops) within High-Availability (HA) environments, alongside a history of building robust telemetry and logging systems for production monitoring.
