Apple is an American multinational technology company founded in 1976 by Steve Jobs, Steve Wozniak and Ronald Wayne, and headquartered in Cupertino, California. It designs and sells consumer hardware including the iPhone, Mac, iPad, Apple Watch, AirPods and Vision Pro, together with the operating systems and silicon that run them. A growing services division built around the App Store, iCloud, Apple Music, Apple TV+ and Apple Pay now contributes a large share of profit, making Apple one of the most valuable companies in the world.

Apple’s Trusted Execution team in the Security Engineering and Architecture organization builds the technology that keeps our users safe and care-free while running the software that they want. Our software runs on the execution path for every program on all of our products. We’re often referred to as the first line of defense in Apple’s defense-in-depth strategy. Our products are infamous within the security community, and each year we push them to the next level. We’re a small team with a huge impact.

As an engineer joining this team, you would be contributing to the entire system. Interacting with Apple’s unique CPU features directly, through the kernel, up through libraries, frameworks and applications. You will have an opportunity to define, design and implement new security technologies for Apple’s next generation operating systems and products.

Successful candidates will be capable of pursuing challenging wide-ranging engineering problems anywhere in the software stack, determining the appropriate compromise between several often competing factors such as ease of use, performance and of course security. Our environment fosters product innovation, rapid product iteration, and a liberating amount of autonomy in which you will be expected to create and quickly bring to market new security methods and technologies to address the complex needs of mobile and distributed computing. The position will require you to interact with and influence many people from several organizations within and outside the company. If you have an interest or background in this area, we’d love to hear from you.
