Airbnb was born in 2007 when two Hosts welcomed three guests to their San Francisco home, and has since grown to over 4 million Hosts who have welcomed more than 1 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 JoinAt Airbnb, our mission is to create a world where anyone can belong anywhere. The Identity Infrastructure team is responsible for securing the foundational platforms and cloud environment that power Airbnb. We provide secure, scalable and verifiable identities to all the entities in our platform (services, nodes, developers etc.). These identities allow each entity to communicate confidently with each other and with the cloud according to well-defined policies and guardrails.Airbnb is a member of the Cloud Native Computing Foundation’s end user community and regularly meets with peer companies to discuss cloud native engineering challenges at scale.The Difference You Will MakeAs a software engineer on this team, you'll work with the fundamental infrastructure components that all other teams at Airbnb build upon, such as our compute platform, cloud services, service mesh, cloud provisioning and networking stack. With users around the world, reliability, scalability, efficiency and high availability are our team’s core concerns and security underlies all of these.
