We make TiDB, an open source distributed scale-out database that is always online and MySQL compatible. Our underlying distributed key-value layer, TiKV, is a CNCF project.
Our tech stack is Rust, Go, Kubernetes, and TiDB itself! Many different technical skill sets can be put to use here. You can work on making TiDB run in the cloud, do low-level database hacking, or working with customers.
