We are the Apple Services Engineering (ASE) Security Red Team. We focus on deep technical security review work of critical ASE services and infrastructure. These security reviews will be scoped and focused on review depth and quality. We are growing our team and looking a Senior Staff Security Engineer to lead deep reviews that identify meaningful security improvement opportunities. In this role, you will work closely with the security engineering, InfoSec, privacy, SRE, detection and design review teams to keep Apple's services secure for our users. You will identify security weaknesses, validate and design detection mechanisms, and provide actionable recommendations to enhance our security posture. You will go beyond simple to find risks and identify obscure and complex risks within complex services. You will collaborate with various architecture and engineering teams to continuously validate and improve our security controls and detection capabilities, with a strong focus on developing repeatable testing frameworks and metrics-driven security improvements. If you love diving into complex and important systems, and driving the security of that system over time, we want to talk to you!
