Introduction

Data is critical to the success of every organisation in Airbnb. It is the foundation on which business intelligence insights, experimentation, Machine Learning (ML) models, analysis and publicly shared company performance metrics are built. The best insights and ML models are worthless without trustworthy data.


Data Engineers at Airbnb are responsible for ensuring the company has trustworthy data for innovation & operations. They play a unique role of bridging the gap and connecting data producers (typically Software Engineers who own the online source systems) to data consumers (typically Analysts, Data Scientists and Software Engineers building applications which rely on the data). 

The role of a Data Engineer is critical to the success of any data driven organisation. Data Engineers deliver business value by increasing both confidence in the integrity of decision making and productivity of data consumers across the company. This document defines the role of a Data Engineer at Airbnb.
