Senior Software Engineer Guest & Host

We're looking for a Senior Software Engineer to help build and scale the backend systems behind user identity and privacy. You'll be reasoning about relationship-scoped access (who's allowed to see this, given the specific context they're asking from), and building systems that other teams across the company depend on to do the same correctly.

You'll work across true backend fundamentals: service architecture, data modeling, authorization logic, and migration tooling that needs to run safely at Airbnb's scale without breaking the dozens of teams who consume these systems.
