<div>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.</div>The Community You Will Join: As part of the Account Integrity team, you’ll be at the forefront of protecting every step of the Airbnb user journey—from first sign-up and login, to booking, messaging, managing accounts, and beyond. Our work goes far beyond just account creation or access: we proactively detect, prevent, and respond to fraud and abuse wherever it may occur, ensuring a safe, trusted, and seamless experience for both guests and hosts. We leverage data-driven heuristics, advanced machine learning, and human operations, allowing us to balance strong protections with low friction for trustworthy users. You’ll work side-by-side with talented product managers, data scientists, engineers, fraud intelligence, and operations teams. Together, you’ll design and build solutions that have direct, meaningful impact on user trust, business success, and the global Airbnb community. If you’re passionate about cross-functional collaboration and making a measurable difference at scale, this is the team for you. The Difference You Will Make: As a Software Engineer (G9) on the Account Integrity team, you will actively contribute code and ideas that shape the features and defenses protecting millions of Airbnb users. You’ll have the opportunity to own and deliver projects end-to-end, from architecting robust backend systems for detecting, investigating, and responding to suspicious behaviors, to optimizing existing services for scalability and reliability. You’ll dive into real-world challenges, such as account takeover, fake accounts, and bots. Your work will help reduce the risks posed by bad actors, while ensuring our platform remains easy and welcoming for everyone else. As you develop your skills, you’ll see the tangible impact of your contributions—helping real users stay safe and confident as they travel, host, and connect on Airbnb.
