The App Store Analytics Quality Engineering team ensures the accuracy, reliability, and integrity of customer experience data that powers features and insights across the App Store ecosystem. We are seeking a test automation engineer with strong experience in Big Data environments (Spark, Kafka, Flink, Hadoop, Hive, Iceberg), backend, and UI service testing and the ability to build scalable, robust test automation using Java or Python. This role is central to ensuring quality throughout the data lifecycle — from client instrumentation to backend aggregation and reporting dashboard — by applying shift-left testing principles, embedding quality checks early in development, and integrating test automation within CI/CD pipelines.
