Software Engineer, Trust Graph

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

Everyone at Airbnb thinks about trust, but our team obsesses over it daily. At the core of trust is safety, and thus we spend a significant amount of our time and energy keeping the community safe. The Trust team is responsible for protecting our community and platform from fraud while also ensuring our hosts, guests, homes, and experiences meet our high standards. We constantly work to fight against online fraud (such as monetary loss, compromised accounts, spam and scam in messages, fake inventory, etc.) as well as offline fraud (theft, property damage, personal safety, etc.). We also work on onboarding and screening of users, and think about complex topics like identity and reputation to ensure that every interaction with Airbnb helps build trust in us and our community. Trust Engineering is responsible for the technology vision and development of a complex stack that runs on every key interaction on the platform.

The Difference You Will Make

Connected Accounts (aka Trust Graph) is a knowledge graph platform that models connections between Airbnb users. It helps identify fraudulent users who try to circumvent existing defenses by creating duplicate accounts or collude to execute fraudulent transactions. We also build and maintain various ML models trained on top of this graph data model. As a Senior Software Engineer on the team, you will be owning and driving critical initiatives that help maintain the Trust and Safety of Airbnb platform. This role requires strong cross-functional collaboration with various product and platform teams to help shape the long term technical vision for the team.
