Senior Security Software Engineer EDR

Summary: The Detection team within Apple Services Engineering (ASE) is responsible for finding any threat actors attacking approximately three quarters of Apple's systems and services. We do this by partnering closely with engineering teams to build a deep technical understanding of how their systems work, and a comprehensive understanding of the threats against them.

A growing part of that mission is the endpoint detection and response (EDR) technology we build ourselves. It is a Swift-based agent that runs on Linux (x86 and ARM64) and on Apple operating systems running on Apple silicon. It collects security telemetry, evaluates detections directly on the host, and takes response action on the host. It also supports Apple's Private Cloud Compute (PCC), the system that extends the privacy and security of Apple devices into the cloud and runs the larger models behind Apple Intelligence. Most of your work will be on Apple's own internal servers, and some of it supports public-facing products used by hundreds of millions of people.

Description: We are looking for an exceptional engineer to help us grow this agent to protect a very large fleet, and to do it without ever taking production down. You will bring two things at once: the engineering depth to ship new capabilities quickly, and a reliability mindset that treats every release as something that runs on production hosts. You will take vague, high-stakes problems and turn them into working software, working with other teams to find out what to build and how. This is not a role where you will be handed pre-defined tickets.
