Software Development Engineer in Test, Siri AI QE

Join the team redefining what a deeply personal and integrated assistant can be. As part of the Siri organization, you will help shape one of the world's most widely used AI assistants, powered by our next-generation of Apple Intelligence. Your work spans personal context understanding, on-screen awareness, and system-level actions built with privacy at the core. In this role, you will hold direct responsibility for shipping features with uncompromised quality across iOS, iPadOS, macOS, watchOS, and visionOS. We are looking for a top-tier Software Development Engineer in Test who pairs strong software engineering and test architecture fundamentals with cutting-edge expertise in agentic AI. If you are an organized, self-directed engineer who thrives as an end-to-end Feature Quality DRI—knowing exactly when to write robust deterministic code and when to deploy agentic harnesses—this is the opportunity to make an outsized impact. In Siri AI Quality Engineering, you will ensure Siri delivers the right experience in the right context—across all Apple devices, system configurations, and real-world conditions. As a Software Development Engineer in Test in Siri AI Quality Engineering, you will serve as a Feature Quality Directly Responsible Individual (DRI), shaping end-to-end quality strategy from early feature design stages through public release. In this role, you will architect comprehensive validation strategies that balance robust, deterministic test automation with novel agentic test harnesses designed to evaluate non-deterministic, contextual AI interactions. You will exercise sound engineering judgment—knowing when to write clean, maintainable programmatic automation and when to deploy agentic workflows—while coordinating targeted manual validation to capture what automation cannot yet reach, systematically shrinking manual overhead every release cycle.
