Build and maintain Feature Store pipelines that ingest and process behavioral, clinical, engagement, and Rx data signals
Design and develop ML training datasets, including batch and real-time feature pipelines, dataset versioning, and training/evaluation splits
Integrate and normalize multi-source data such as Kafka event streams, Adobe Analytics data, and healthcare datasets
Develop and optimize large-scale data processing jobs using Apache Spark (Dataproc) for feature engineering and model input preparation
Monitor and improve data quality for ML models, including tracking feature freshness, identifying data drift, and ensuring pipeline reliability
Partner with engineering teams to define data schemas and event structures that support downstream machine learning workflows
Ensure secure and compliant handling of sensitive data, including masking, de-identification, and maintaining auditability within data pipelines
Support data resiliency efforts, including disaster recovery planning, data replication strategies, and dataset lifecycle management
Maintain clear documentation of data pipelines, feature definitions, and lineage to support model transparency and operational efficiency
