Sr Automation & Intelligence Tools Engineer, SEAR

SPEAR is a team of engineers in Apples Security Engineering u0026 Architecture (SEAR) organization focused on strengthening security across all of Apples operating systems. We work in a lot of different codebases at every layer of the stack on features that ship to over a billion people without getting in their looking for a senior engineer to build the automation and intelligence tooling that lets us ship that work with confidence. Youll design the harnesses infrastructure and AI-assisted workflows that make correctness verifiable across iOS macOS watchOS tvOS and visionOS. Help us accelerate our security hardening work with the AI tooling to match its scale.

Youll join a multi-functional team covering every layer of the operating system - from apps to the kernel - working directly with feature engineers in SEAR and across the wider OS to day youll decide where automation is worth building then build it. You own the question of how this team proves that security-critical code does what it claims without degrading the experience for our customers. You will also help us define AI-native security-based development by assessing where agents accelerate our work and where manual testing and human oversight remain necessary to safeguard the customer experience.

Strong programming skills in Swift Objective-C or Python with a track record of building tools frameworks or infrastructure that other engineers depend designing and deploying automated verification at scale including harnesses and CI systemsnReal fluency with AI-assisted development. You use LLMs coding agents or tooling youve built yourself to get substantially more done and you can explain owned an ambiguous technical problem that crossed team boundaries and driven it to something that actually can explain a technical trade-off clearly enough to change a partner teams mind.

Youve built agentic or LLM-backed developer tooling such as evals harnesses MCP servers or code-generation pipelines and you have opinions about where it holds up and where it falls with XCTest Xcode and working in large shared in security systems-level or platform setting test strategy: assessing risk deciding whats worth covering triaging and about how systems work end to end and the patience to find out.
