Staff Software Engineer, Payments Funds Ledger

Details

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.

The Community You Will Join:

Airbnb’s mission is to create a world where anyone can belong anywhere. Airbnb Payments team supports this mission by economically empowering Airbnb businesses and our global community of guests and hosts.

The Payments Funds Ledger team is part of the core platform within the Airbnb Payments ecosystem. Our mission is to enable real-time, reliable, and scalable tracking of money movements and balances for Airbnb and its users—bringing transparency and trust to every transaction.

We build and operate the fund management system that serves as the single source of truth for all types of value on the Airbnb marketplace—such as guest payins, host payouts, incentives, and stored value—ensuring strong financial integrity and traceability of funds. We also help secure money movements by providing freeze capabilities that allow us to control the flow of funds in response to suspicious activity or regulatory restrictions. In addition, our systems offer advanced reconciliation capabilities that help detect issues with money movement early and ensure consistency across various components of the platform.

We work closely with all Payments functions, as well as the Risk & Compliance, Trust, Data and Finance teams, moving over $140 billion in funds annually across 190+ countries and more than 70 currencies.
