At Nextdoor, the Core Services team is responsible for operating critical high throughput services which power the communities on the Nextdoor platform worldwide. We operate the core datastores and critical services, most recently building a distributed, multi-tiered distributed cache with zone aware routing in Golang making use of Istio’s Locality aware routing to serve 20M+ QPS. Other recent projects include introducing Strimzi to deploy Kafka and building a kubernetes native postgres connection pooler.

The primary focus of the team is an iterative investment in a distributed, globally replicated graph store with high availability tiered caching. This datastore will provide predictable performance and aims to enable product engineers to move quickly without thinking about RDBMS database performance/migrations and will enable a fundamental architectural shift at Nextdoor towards a globally available single distributed application.

You’ll work with product engineers to understand their pain points and identify high leverage opportunities to improve developer experience and scalability of our systems. Our goal is for the infrastructure to do the heavy lifting so that our product engineers can spend every minute of their time focused on their product areas and metrics.
