Software Development Engineer in Test (SDET)
As an SDET you will create and maintain sophisticated testing infrastructure that validates the reliability and performance of Apple's most strategic developer frameworks. Your primary focus will be developing comprehensive test automation for FoundationModels, ensuring that developers can seamlessly integrate advanced machine learning capabilities into their applications. You'll design and implement automated test suites that cover functional, integration, and regression testing across iOS, macOS, and visionOS platforms, while collaborating closely with framework engineering teams to understand expected behaviors and track evolving features.
Your day-to-day responsibilities will include prioritizing automation results from various testing pipelines, validating developer Xcode workflows including Previews and Simulator functionality, as well as maintaining robust test harnesses that facilitate comprehensive validation scenarios. You'll work to validate processes for critical testing phases, setting up and configuring test environments across multiple platforms, and ensuring that build and deployment processes remain stable and reliable. Additionally, you'll contribute to improving test coverage for new framework features, enhance test quality to facilitate easier triage, and maintain automated testing pipelines while staying closely aligned with framework development teams to anticipate and validate upcoming functionality changes and improvements.
