Cloud Network Engineer, Infrastructure Services

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 Apples 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.

Were looking for a Principal-level engineer to own and run a critical slice of our hyperscale cloud network as if it were their own business. This is a global network spanning massive scale, deep complexity, and constant evolution and it needs someone who doesnt just design for it, but takes end-to-end accountability for its health, growth, and future. Every day, our hyperscale Apple Cloud network moves traffic across a footprint of VPCs, subnets, gateways, and transit architectures that span the globe, powering services relied on by millions. At this scale, small decisions compound quickly, and the difference between a good architecture and a great one shows up in resilience during failure, efficiency under load, and how gracefully the system absorbs growth. Youll be the person closest to that reality, thinking not just in terms of uptime and design reviews, but in terms of risk, cost, and long-term strategic tradeoffs, the way a business owner would. This role sits at the intersection of network engineering, distributed systems, and compute infrastructure. Youll bring deep technical fluency across all three domains, but just as importantly, the judgment and business instincts to know where to invest engineering effort for maximum impact. Youll operate like an owner: someone who sees a problem, doesnt wait to be asked, and drives it to resolution because its the right thing for the business, not because its in the job description. If you get energy from taking ambiguous, high-stakes problems and turning them into clear technical strategy, and if you want the kind of ownership usually reserved for founders, applied at hyperscale, this is the role for you.Own the framework for modeling deployment scale and complexity across the cloud network (VPCs, subnets, routes, gateways, peering, transit), forecasting and stress-testing against architectural limits. Identify emerging complexity and scale risks 12-24+ months ahead of impact, shaping roadmaps to address them before they materialize. Serve as the orgs principal authority on availability and reliability, defining SLO frameworks grounded in real user/service impact. Lead the most complex, cross-cutting reliability initiatives end-to-end, driving systemic architectural fixes (not one-off patches) from incidents and postmortems. Establish org-wide standards for availability engineering, blast-radius reduction, and failure-domain isolation.

Serve as the senior technical representative of Cloud Network in major infrastructure-wide initiatives, building trust with senior leaders and engineering peers to align competing priorities. Articulate complex tradeoffs and long-term technical strategy to executive/cross-functional audiences, shaping company-level decisions where cloud network architecture is critical. Set architectural standards adopted org-wide, mentor senior/staff engineers, and act as the escalation point for the highest-severity or highest-ambiguity production problems. Stay current with industry trends in cloud networking and bring relevant innovations back to the team.8+ years of experience in network engineering, with substantial experience operating large-scale networks in cloud or hybrid environments Demonstrated experience owning production availability and driving incident response for business-critical infrastructure Strong hands-on knowledge of core networking concepts (BGP, DNS, load balancing, VPCs, SDN) and cloud-native networking (Kubernetes CNI, service mesh, overlay networks) Experience leading cross-functional or cross-team technical projects from design through execution Excellent written and verbal communication skills with the ability to clearly articulate risk, reliability trade-offs, and operational priorities to both engineering teams and senior leadershipExperience operating at architect level with a track record of technical leadership beyond your immediate team Background spanning both network and compute infrastructure domains Experience building and tracking SLOs/error budgets and driving org-wide reliability programs History of pitching new technical initiatives and securing organizational investment or buy-in
