Preferred Qualifications: • Experience testing machine learning systems, such as recommendation systems, search ranking systems, or other probabilistic ML application systems. • Experience creating synthetic or seeded test data to simulate realistic customer/account behaviors. • Experience evaluating model outputs using statistical techniques, distribution analysis, or scenario-based validation, rather than deterministic assertions. • Knowledge of data pipelines, feature stores, inference systems or model-serving infrastructure (Seldon, KServe, Ray Serve, etc.) is a plus. • Experience with performance and load testing tools • Experience with Databricks or similar ML platform tooling • Experience architecting and optimizing CI/CD pipelines, quality gates, and release validation systems using Jenkins or similar platforms.
