Architect, Perimeter and Network Security, Enterprise Technology Services

At Apple, new insights often become revolutionary products, services, and customer experiences very quickly. Bring passion and dedication to your job, and there's no telling what you could accomplish. The Emerging Technologies team within IS&T specializes in building forward-looking, extremely scalable systems and solutions in two areas: Information Security and general-purpose, reusable platforms in the space of Integration and Orchestration. The team has a passion for solving challenging problems, exploring new domains, and engineering transformational solutions. We operate with a startup mindset - lean teams, high ownership, and technical leaders who flex across domains to build and scale new capabilities.

The Emerging Technologies team is seeking an industry-recognized Architect to serve as the domain expert for Apple's perimeter and network security platform. You will be the technical authority across the full traffic path - edge proxies, origin/application load balancers, service mesh, and API & AI security gateways - architecting the defenses that protect Apple's services at scale. We are looking for someone who brings deep, proven expertise in perimeter security, threat mitigation, and proxy technologies - a technical leader whose experience and reputation precede them.\n\nIn this role, you will own the architecture and technical direction of the systems that deliver Apple's security capabilities - WAF protection against OWASP threats, DDoS mitigation, Bot Prevention, TLS termination/origination, real-time threat intelligence, and security policy enforcement across protocols (TCP, UDP, HTTP/HTTPS). These capabilities are powered by L4/L7 proxy runtimes and a Java-based orchestration platform that manages configuration, policy distribution, and lifecycle management at fleet scale. You will define the long-term security architecture vision, drive technically complex initiatives end-to-end, and shape how these systems evolve across on-premises data centers and public cloud environments (Google Cloud Platform, AWS), ensuring Apple's defenses remain resilient, adaptive, and secure as threats and scale grow.\n\nThis is a deeply technical, hands-on role for a recognized industry expert. You are expected to write code, prototype solutions, lead design efforts, and raise the technical bar for the entire team - not through management authority, but through expertise, influence, and the quality of your work. This role is also deeply cross-functional - you will partner with Apple's security and cloud infrastructure teams to drive a unified security vision, and work directly with application teams across the company to understand their traffic patterns and solve their integrated security needs.\n

Bachelor's degree in Computer Science, Computer Engineering, or equivalent.\n15+ years of hands-on software engineering experience with significant time spent in security architecture or senior technical leadership roles.\nExpert-level understanding of perimeter and network security: WAF design and rule authoring, DDoS mitigation strategies, bot detection techniques, TLS/mTLS, TCP/IP, HTTP/HTTPS, QUIC, and DNS security.\nDeep experience with proxy technologies (NGINX, Envoy, HAProxy) across edge, origin, service mesh, and API & AI security gateway tiers - including protocol-level internals, security module/filter architectures, and load balancing strategies. Solid understanding of IP networking fundamentals including BGP and NAT.\nExperience designing and building orchestration/control plane systems for security policy distribution and configuration management across distributed infrastructure at scale.\nProven ability to architect systems that span on-premises and public cloud (Google Cloud Platform, AWS) with high availability, fault tolerance, and security as first-class concerns.\nStrong proficiency in Java/J2EE for building backend platforms. Ability to write production-quality code and lead by example.\nDemonstrated track record of driving security architecture strategy and making high-impact design decisions across multiple teams or products.\nExperience working cross-functionally with security, cloud infrastructure, and application teams to deliver integrated traffic and security solutions.\nExcellent written and verbal communication skills - ability to produce clear architecture documents and present complex security concepts to diverse audiences, from engineers to executives.

Experience with proxy engine internals - C, C++, Lua, or WASM-based customization of NGINX, Envoy, or similar engines for implementing security controls in the runtime data path.\nDeep knowledge of authentication/authorization frameworks (OAuth, mTLS, certificate management) and secure software development lifecycle practices.\nExperience with service mesh architectures (Istio, Envoy-based), API & AI security gateway patterns, containerization (Kubernetes, Docker), and infrastructure-as-code (Terraform, Ansible).\nExpertise in distributed systems design patterns - consensus protocols, eventual consistency, data replication, and partition tolerance trade-offs.\nExperience designing real-time data pipelines and event-driven architectures for threat intelligence or security telemetry at scale.\nKnowledge of observability at the platform level - designing systems for meaningful security logging, metrics, distributed tracing, and alerting.\nFamiliarity with OWASP threat models, CVE analysis, threat landscape trends, and security incident response from an engineering perspective.\nComfortable working across Java, Python, Go, and scripting languages as the problem demands.\nRecognized industry expertise in perimeter/network security - demonstrated through contributions to open-source security projects, conference talks, or a track record at companies operating security infrastructure at internet scale.\nNamed inventor or co-inventor on granted patents or patent applications in networking, security, or distributed systems.\nContributor or author of IETF RFCs, Internet-Drafts, or equivalent standards documentation, influencing industry protocols and best practices.\nPublished technical papers, whitepapers, or research articles in reputable conferences, journals, or industry forums.\nM.S. or Ph.D. in Computer Science, Electrical Engineering, or equivalent experience.
