## Description

Join Apple's Quality Engineering organization as a Software Development Engineer in Test (SDET) focused on Swift Intelligence Frameworks, with an emphasis on Foundation Models Framework and App Intents. In this role, you will be at the forefront of quality for the frameworks that empower millions of developers to create the next generation of intelligent applications. Testing artificial intelligence requires rethinking traditional quality assurance. We are looking for someone who is not just an expert in test automation and API testing, but who is genuinely excited and eager to pioneer new, creative approaches to testing non-deterministic AI features. You will collaborate closely with cross-functional teams to understand complex framework behaviors, design robust test strategies, and ensure seamless integration across Apple's entire ecosystem-including iOS, watchOS, macOS, and visionOS., As an SDET, you will create and maintain sophisticated testing infrastructure that validates the reliability, performance, and inclusivity of Apple's most strategic developer frameworks. Your primary focus will be developing comprehensive, multi-platform test applications to evaluate in-development Swift APIs. Through this work, you will provide vital feedback that ensures developers can seamlessly integrate advanced machine learning capabilities into their apps. You will design and implement automated test suites covering functional, API, integration, and regression testing across all of Apple's platforms (iOS, macOS, tvOS, watchOS, and visionOS)., Your day-to-day responsibilities will involve prioritizing triaging automation results from various testing pipelines and validating critical developer workflows in Xcode, including Previews and Simulator functionality as well as doing hands-on testing as needed.

You will maintain robust test harnesses that facilitate comprehensive validation scenarios, configure test environments across multiple platforms, and ensure build and deployment processes remain exceptionally stable.

Working closely with framework engineering teams, you will champion the developer experience, anticipate upcoming functionality changes, and drive continuous improvement in our testing methodologies for next-generation AI tools.
