The Data and Storage Services team builds Affirm's data infrastructure across OLTP and OLAP systems—from critical online checkout databases to batch orchestration, streaming infrastructure, and large-scale analytical platforms. This role focuses on Affirm's Lakehouse Platform, built on Apache Iceberg as a foundational technology for scalable analytical data storage, table management, and interoperability across compute engines like Spark and Snowflake.
