Job description
Apple’s Security Engineering & Architecture organization protects the systems and experiences used by people around the world. The ML Security Engineering team brings together machine learning, systems security, and product engineering to help ensure that Apple Intelligence and other AI-powered experiences are secure, private, and trustworthy. We are seeking an AI Systems Security Engineer to design, build, and deploy the security foundations for agentic and tool-using AI systems. You will develop the architectural controls that govern how agents access tools, services, memory, user data, and other privileged capabilities—and ensure those controls remain effective when models encounter malicious, untrusted, or adversarial inputs. You will work closely with ML security researchers, AI/ML platform teams, operating-system engineers, product security, privacy, and product teams. Research will identify emerging attacks and promising defenses; you will translate those findings into robust platform capabilities, reusable frameworks, launch requirements, and production protections.
Success in this role is measured by security properties that can be enforced, tested, observed, and maintained across shipping systems.
