Join us and build for travelers everywhere. Expedia Group seeks a motivated and results-oriented Senior Software Engineer to join our Data Lake and Catalog team.

As a Senior Software Engineer on an industry-leading data platform, you will build the core of Expedia Group’s Lakehouse and data discoverability capabilities, evolving how we store, govern, and expose data so product and analytics teams can easily find, understand, and trust the data they need. You will collaborate with experienced software engineers and cross-functional partners to improve our technology, design and develop new services and software solutions, and build and track metrics to ensure high-quality results.

You will contribute to technical direction through strong engineering judgment, influence system design, and work closely with business partners to turn product vision into scalable, reliable systems. We love contributing our work to open-source communities and have successfully done so with tools like Circus Train , a Hive dataset replication tool, and Waggle Dance , a federation service that allows access to data lake tables across multiple catalogs.

Recently, we added Hive support to Apache Iceberg , a high-performance open table format for large analytic datasets that underpins many modern Lakehouse architectures. We guarantee you’ll learn a lot and won’t be bored!
