## Job description

Apple’s OS Security team is looking for a motivated software engineer to design, build, and deploy world-class containment and isolation mechanisms throughout our operating systems. As part of the Security Engineering and Architecture group, you will develop the foundational technologies—including compartmentalization, mandatory access control, and robust policy engines—that ensure our platforms are resilient and never just one mistake away from compromise.
