Anomaly Detection for Airbnb's Payment Platform - Airbnb Engineering

With hosts and guests around the globe, Airbnb aspires to provide a frictionless payments experience where our guests can pay in their local currency via a familiar payment method, and our hosts can receive money via convenient means in their preferred currency. For example, in Brazil the currency is Brazilian Real, and people are familiar with Boleto as a payment method. These are quite different than what we use in the US, and imagine this problem spread across the 190 countries Airbnb serves. In order to achieve this, our Payments team has built a world-class payments platform that is secure and easy to use. The team's responsibilities include support of guest payments and host payouts, new payment experiences like gift cards, and assisting in financial reconciliation, to name a few.
