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 Backend Test Engineer with strong experience in Big Data environments (Spark, Kafka, Flink, Hadoop, Hive, Iceberg) and the ability to build scalable, robust backend 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 - by applying shift-left testing principles, embedding quality checks early in development, and integrating test automation within CI/CD pipelines.
Description
In this role, you will drive quality for large-scale distributed data systems that power App Store analytics. You will collaborate closely with engineering, data, and program management teams to define test strategies, contribute to automation frameworks, and ensure high data fidelity across ingestion, transformation, and reporting layers. You will be responsible for:
- Implementing and maintaining automated validation frameworks for data pipelines and services
- Integrating automated tests into CI/CD pipelines to ensure continuous feedback and early defect detection
- Partnering with developers to shift quality left by embedding testability into data workflows and APIs
- Ensuring consistency and correctness of client-to-backend data flows across iOS, macOS, tvOS, and Web
This role requires a self-driven engineer with strong technical depth, solid analytical skills, and the ability to influence quality across complex, evolving systems.","responsibilities":"Design, implement, and maintain automated test frameworks for backend data validation, ETL verification, and system integration testing
