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.</p> <p>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. We created a dedicated management cluster to run ArgoCD, Loki, Prometheus, and Grafana. Additionally, we have created a second Kubernetes cluster for Nextdoor applications to ensure we can scale beyond the limitations of a single cluster. This will ensure Nextdoor’s infrastructure is able to scale for many years to come.</p> <p>Additionally our team has focused efforts to modernize our Infrastructure as Code (IaC) by leveraging CDK to manage our AWS resources and Pulumi to manage our other core infrastructure systems such as PagerDuty, Datadog, and Sentry.</p> <p>At Nextdoor, we offer a warm and inclusive work environment that embraces a hybrid employment experience, providing a flexible experience for our valued employees.</p> <h4><strong>The Impact You’ll Make</strong></h4> <p>You will be responsible for building an efficient and scalable container and serverless computing environment for our product developers. In this team you will work in the ways of reliability engineering, design scalable systems from the ground up, and generally build systems that never page you.
