Airbnb was born in 2007 when two hosts welcomed three guests to their San Francisco home, and has since grown to over 5 million hosts who have welcomed over 2 billion guest arrivals in almost every country across the globe. Every day, hosts offer unique stays and experiences that make it possible for guests to connect with communities in a more authentic way. As part of the Application Platforms organization, the Data Frameworks team builds foundational data products that enable scalable, consistent, and performant access to application data across Airbnb. We serve a broad set of internal partners - including product engineering, machine learning, and infrastructure teams - by providing interfaces that bridge the gap between transactional and analytical data needs. Our work enables engineers and systems across Airbnb to model, transform, and serve data effectively through unified, intuitive frameworks.
