At Nextdoor, Cloud Engineers are responsible for building, deploying, managing, and securing the underlying cloud-based architecture that powers communities on the Nextdoor platform worldwide. These engineers have designed, built and implemented a globally scalable container and serverless based infrastructure that serves billions of requests a day, millions of active users, and hundreds of developers. We build infrastructure and tooling that is iterable, scalable, and secure.

We write everything in code from network infrastructure to server management, database provisioning, and data pipelines. Recently we have focused on scaling up our Kubernetes infrastructure and IaC using CDK and Pulumi.

We offer a warm and inclusive work environment that embraces a hybrid model, providing a flexible experience for our valued employees.

You will be responsible for building an efficient and scalable container and serverless computing environment for our product developers.
