Apple's Trusted Execution team in Security Engineering and Architecture builds the security technologies that protect every Apple product at the point of code execution. Our work is the first line of defense in Apple's defense-in-depth strategy, well known in the security community, and constantly evolving. We're a small team with a huge impact. As an engineer joining this team, you would help ensure the integrity of the systems that control what software is authorized to run on Apple hardware — and under what circumstances. These systems span client devices, server infrastructure, and hardware security modules, and your work will require understanding how they interact to enforce security policy end-to-end. You will analyze these systems for security gaps, help define and enforce authorization policies, and build automation and analytics to strengthen oversight and detect anomalies. Successful candidates will be versatile software engineers with a security mindset — able to reason about complex systems, identify threats, and build the right solution whether that means writing a security analysis, automating a process, or contributing code to the operating system. Our environment fosters product innovation, rapid iteration, and the autonomy and support to do your best work. The position will require you to collaborate with and influence teams from several organizations across Apple. As you grow in the role, there will be opportunities to work deeper in the stack, contributing to the operating system security technologies that run on every Apple device. If you have an interest or background in this area, we'd love to hear from you.
