What is Build Infrastructure at Airbnb?

Every day, developers at Airbnb ship on the order of 1,000 changes across thousands of microservices. The Build Infrastructure (BuildInfra) team at Airbnb develops, deploys, and maintains the software that every Airbnb developer uses to build services and shared libraries. BuildInfra is part of our larger Developer Infrastructure team.

As Airbnb's business and engineering team have grown, we have adopted a microservices architecture. We write most of our microservices in Java. The source code for all of these services, and the internal libraries they share, lives in a monorepository called Treehouse. Treehouse has 2M lines of code, and hundreds of developers triggering thousands of builds per day; we expect Treehouse to grow by a factor of 5x in the next two years. Our BuildInfra team uses state of the art techniques, such as distributed builds and shared artifact caches, to ensure incremental and full builds are as fast as possible.

Our team is impactful and high-leverage: we make the entire engineering organization more productive. You will have visibility into every other engineering team and their systems, and you'll engage in helping and mentoring them.
