Senior Software Engineer, Payments Platform

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.

You'll join the Payments Platform Engineering team, which owns everything involved in settling money in Airbnb's global marketplace, from collecting guest payments to paying out hosts. The team builds the platform behind all of Airbnb's lines of business, across infrastructure, core payment services, and user-facing payment experiences. You'll work closely with product managers, data scientists, designers, and operations, as well as engineering teams across Airbnb.

You'll design and build the next generation of Airbnb's Payments Platform: scalable, highly available systems that process massive daily transaction volume. Success means shipping reliable, well-instrumented services and product features end-to-end, with strong code quality and observability, while making Airbnb the safest and easiest-to-use payments platform.
