Security Domain Expert, Perimeter and Network Security, Enterprise Technology Services

Sunnyvale, California, United States Software and 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 a Security Domain Expert to serve as the outward face and technical authority of Apple's perimeter and network security platform. You will represent the team across Apple — in architecture forums, security reviews, and leadership briefings — bringing deep expertise in perimeter security, proxy technologies, and threat mitigation to every engagement. This role requires hands‑on experience with the technologies at the heart of our platform — proxies, origin, edge, application load balancers, service mesh, API & AI security gateways, WAF, DDoS mitigation, bot prevention, TLS termination/origination, and security policy enforcement across protocols (TCP, UDP, HTTP/HTTPS).

You will apply that expertise to advise partner teams on how our security capabilities address their traffic and security challenges, and to represent the team's technical perspective in cross‑organizational forums. You will also serve as the bridge between our engineering team and the broader Apple ecosystem — working directly with application teams to understand their security requirements, synthesizing cross‑team needs to inform platform strategy and roadmap, and translating technical security concepts into clear narratives for leadership.

This role spans deep technical engagement with security and infrastructure teams through to executive communication in equal measure.

• Serve as the domain authority for perimeter and network security across the Emerging Technologies organization — providing expert guidance on WAF, DDoS mitigation, bot prevention, TLS management, real‑time threat intelligence, and security policy enforcement across proxy tiers.
• Represent the security platform in architecture forums, security reviews, cross‑organizational reviews, and leadership briefings — serving as the team's technical voice in all external settings.
• Advise application teams across Apple on their traffic patterns and security requirements, articulating how the platform's capabilities — across edge proxies, origin/application load balancers, service mesh, and API & AI security gateways — address their specific needs.
• Evaluate emerging threats, attack vectors, and defensive technologies — bring industry perspective to shape the team's security strategy and keep Apple's defenses at the forefront.
• Drive alignment on cross‑organizational security initiatives — build consensus on priorities, trade‑offs, and sequencing for efforts that require coordinated action across security, infrastructure, SRE, cloud, and application teams.
• Synthesize cross‑team intelligence — bring insights from partner engagements and organizational priorities back to the engineering team to inform and influence platform strategy and roadmap direction.
• Partner with the platform architect and engineering managers to ensure the team's technical direction — defense‑in‑depth strategy, threat coverage, and platform evolution across on‑premises and cloud environments (GCP, AWS) — reflects real‑world security needs.
• Contribute to technical design reviews and security architecture discussions, bringing the external perspective of partner team requirements and cross‑organizational constraints.
• Assess gaps in cross‑organizational security coverage; proactively recommend…
