Senior Network Security Engineer, Infrastructure Services

Apple

About The Position

Join Apple’s Information Systems and Technology (IS&T) organization as a Senior Network Security Engineer. IS&T is responsible for Apple's global technology systems, supporting billions of devices and transactions. Infrastructure Services, a part of IS&T, manages data center equipment and systems, providing compute, storage, and networking services. This is a hands-on engineering role focused on designing, deploying, automating, and troubleshooting resilient enterprise network services. You will collaborate with various teams to design, engineer, and improve network services, focusing on Zero Trust and modern secure access architectures. The role involves designing multi-profile VPN services, scaling connectivity, and building automation and AI-driven workflows to evolve from reactive support to predictive, self-healing engineering. The goal is to continuously improve service reliability, security posture, and user/partner experience at a global scale. We seek engineers who are curious, take end-to-end ownership, and solve complex problems through engineering. Successful candidates thrive in collaborative environments, embrace continuous learning, challenge conventional approaches, and leverage software, automation, observability, and AI.

Requirements

8+ years of enterprise experience designing, deploying, and operating global network security, routing, Switching, remote access VPN, and WAN/SD-WAN architectures.
Deep firewall & edge platform expertise: Hands-on mastery of Cisco ASA / Firepower, Palo Alto Networks Firewalls, and Fortinet (FortiGate / FortiOS), including security policy architecture, NAT, NAT64 and platform lifecycle management.
Large-scale Remote Access & Zero Trust: Proven track record engineering multi-profile SSL and IPsec remote access services (split/full tunnel, device posture, per-app VPN) and integrating with modern ZTNA/SSE architectures.
Advanced IPsec & Site-to-Site Connectivity: Deep expertise in IKEv1/IKEv2, PKI/certificate authentication, crypto suites, VTI, DMVPN/FlexVPN, and resilient tunnel architecture for Client to site VPN, partners, 3PLs, and remote sites.
Complex Routing & WAN Edge: Advanced BGP and OSPF routing design across hybrid WAN/SD-WAN environments, including carrier peering, traffic engineering (communities, AS-path manipulation), VRF route-leaking, and L2/L3 segmentation.
Identity & Access Management Integration: Strong experience integrating network access with enterprise IAM systems—RADIUS, TACACS+, SAML/SSO, MFA, PKI certificate lifecycle, 802.1X, and NAC.
End-to-End Troubleshooting & Telemetry: Exceptional packet-level diagnostic skills (pcap, flow analysis, debugs, MTU/path latency issues) across security policies, overlay/underlay networks, and application layers.
Infrastructure Automation & Modern Tooling: Demonstrated proficiency automating network security provisioning and validation using Python, REST APIs, Ansible, or Terraform, with bonus experience leveraging AI/LLM-assisted workflows for operations and triage.
