Role Number: 200608900

The Information Security Machine Learning (ISML) team is revolutionizing Apple’s security services by using machine learning to harness patterns and insights from vast amounts of data to predict, detect, and respond to threats; transforming reactive security into autonomous protection. The ISML team is responsible for improving security services with applied science, developing long term autonomous security solutions with cutting edge research, as well as building and deploying models and infrastructure to support machine learning security solutions.

We're looking for a passionate and highly skilled macOS engineer to join our team and build the foundation for autonomous security on Apple devices. This role requires a deep understanding of the macOS environment and a proven ability to develop and deploy high-performance applications.

Description

As a MacOS ML Engineer, you will build the fundamental software, libraries, tools, and test suites to support autonomous security on Apple devices.

You will develop the software and integrations to make on device security machine learning successful. As part of this process, you will define the architectures and services of autonomous security on-device, including OS interfaces, sensing capabilities, ML scaffolding, and autonomous security capabilities. You will collaborate with Core OS, security, and services partners across Apple to deliver high reliability, high performance device frameworks and services.

You will adapt the intelligence, models, and research developed by the team to run on macOS. Development and deployment of autonomous security on macOS needs to balance privacy, rigor, visibility, performance, and impact. In this role, you need to have skills and knowledge across a blend of macOS development best-practices, systems and software engineering, and embedded systems development.
