# Software Engineer 3

The Kubernetes teams make running MongoDB in and from Kubernetes so frictionless that it is the default database choice for cloud-native applications. Our operators let developers and platform teams provision, scale and operate MongoDB through Kubernetes-native APIs, in their own clusters or in MongoDB Atlas. You will join the Kubernetes Capabilities squad. Our sister squad builds the shared platform layer of the MongoDB Controllers for Kubernetes; we build the capabilities on top of it that users actually adopt. That means bringing MongoDB features such as Search and Vector Search to Kubernetes, extending what our users can deploy and manage declaratively, and owning the Atlas Kubernetes Operator. Our work starts with a user problem and ends with a Kubernetes API that solves it. In practice, we build a platform for other engineers. Our users are developers and platform teams who expect self-service, sensible defaults and APIs that behave predictably. If you have built an internal developer platform, a Kubernetes controller, or any system whose customers are other engineers, you will recognise the problems we work on. No prior experience with MongoDB is required. You will meet most
