Senior Security Engineer, SEAR

Requirements

• Drive and agency: You know how to use tools to learn new areas, experiment, and develop security insights across unfamiliar technologies. You’re curious and interested in explaining. You have a sense of ownership and pride in improving the environment.
• OS security fundamentals: knowledge of contemporary mitigation techniques, vulnerability classes, and security architectures
• Expert proficiency in one or more: Python, Swift, C/C++/Objective-C
• AI/agentic fluency: You have hands-on experience using agentic/LLM-based coding tools. You’re able to build and refine Skills, Agents and AI workflows, not just operate them. You’re able to independently verify or refute a finding rather than accept it at face value

Nice to Haves

• Proven experience building and integrating security-enforcing controls across the full software lifecycle
• Familiarity with Apple platform security architectures (iOS, macOS)
• Knowledge of observability tools and techniques
• Experience building visualisations for complex technical information
• Enthusiasm for new technologies and growth
• Demonstrated ability to architect solutions to ambiguous, cross-functional problems — from initial design through delivery — working independently and in close collaboration with partner teams
• Understanding of vulnerability research concepts, offensive security tooling, or security analysis workflows (static, dynamic, or binary)

What You'll Be Doing

• You will join a team at the intersection of security research and software engineering, where the work you build directly shapes the speed and depth at which Apple can identify and address vulnerabilities.
• Deliver continuous security automation across all of Apple's operating systems and products.
• Generate data-driven insights, advocate for new or improved security interventions, rapid prototyping, scaling up, and evangelising their adoption.
• Collaborate with other parts of Apple on a broad range of technologies and initiatives to enhance security.

Perks and Benefits

• Opportunities for impact across the entire software development lifecycle.
• Technical direction and mentoring for engineers across the team.
• Work cooperatively with various parts of Apple on security design reviews and vulnerability research.
• Potential travel to other Apple sites.
