Trust Engineering at Airbnb:

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 Org 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 and offline fraud. We also work on onboarding and screening of users, and think about complex topics such as identity to ensure that every interaction with Airbnb helps build trust in us and our community. Trust Engineering within Trust Org is responsible for the technology vision and development of a complex stack that runs on every key interaction on the platform.

Your role

We’re looking for a senior staff engineer to join our Foundational Modeling team (part of Trust Engineering) that is responsible for a Machine Learning Platform, a core capability that enables Trust product teams to build machine learning solutions to stop bad actors from doing bad things on Airbnb.

As a senior staff engineer on the Foundational Modeling team, you will help keep Airbnb users safe by working across diverse teams and systems to enable sophisticated safety strategies.
