Senior Network Security 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 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.

This is a hands-on engineering role spanning design, deployment, automation, and deep troubleshooting, where a single tunnel or site outage can stop a supply chain, a launch, or a partner integration.

As a Senior Network Security Engineer, you will partner across software, hardware product teams, infrastructure, architecture, AIS, Operations, and security teams to design, engineer, and continuously improve resilient enterprise network services.

As Apple evolves toward Zero Trust and modern secure access architectures, you will help design multi-profile VPN services, scale partner and remote site connectivity, and build automation and agentic AI-driven workflows that transform from reactive support to predictive, self-healing engineering.

Through curiosity, engineering innovation, and intelligent automation, you will continuously improve service reliability, security posture, and the end-user and partner experience at global scale.

We're looking for engineers who are naturally curious, take end-to-end ownership, and solve complex problems through engineering rather than operational workarounds.

Successful candidates thrive in collaborative environments, embrace continuous learning, challenge conventional approaches, and leverage software, automation, observability, and AI to build intelligent, resilient, and scalable network services that deliver exceptional user experiences.
