What is Payments at Airbnb?

Airbnb is a trusted marketplace and travel community. This level of trust is critical to the success of AIrbnb and has to extend to each payment experience. Payments enables trust and is a core and strategic part of Airbnb fueling growth with easy to use payment services. We are building a world-class payments platform that moves billions of dollars, in 191 countries, with 75 currencies, through a complex ecosystem of payments partners. We build and maintain our own in-house global payments platform because no solution exists with the global reach needed. As the platform grows we’ll be adding new payment partners, global licenses, and building new payment experiences for our guests and hosts.

The Role

Payments as a distributed system has a lot of unique requirements, e.g. we care more about strong consistency, transactional support, high availability, and so on. Traditional key-value stores and the current company wide solution doesn’t fully satisfy Payments’ infrastructural needs. Thus, the Payments team has to build all those infrastructure solutions for ourselves and Payments Foundation team is taking most challenges in this area. The team focuses on the following five areas to support the payments systems’ infrastructure for all other payments sub-teams: Performance, Availability, Load testing, Testability, and Operability. The team is a new team growing fast and has planned many exciting and challenging projects in 2018 and 2019. This team will allow you to take lots of hard core infrastructure challenges in the fintech world.


  • In a distributed payment ecosystem, it is critical to accurately measure and track a transaction’s end to end state and contents to ensure consistency throughout the payment cycle. Without robust tracking, data leakage and errors can occur, resulting in either lost revenue or increased costs for all parties in the payment cycle, including the consumers, merchants, gateways, and acquirers. You can find how Airbnb is measuring transactional integrity.
  • We solve lots of interesting and technical challenging problems such as building state machine framework for idempotency, eventual consistency, sharding for scaling MySql databases and its failover solutions, reliable scheduling framework, reliable events framework, etc.
