About PlanetScale

PlanetScale is growing rapidly and reinventing the database space. The PlanetScale platform offers both PostgresQL and Vitess clusters. Vitess is an open-source database clustering system for horizontal scaling of MySQL, enables businesses to efficiently handle large-scale data workloads — without sacrificing developer experience. We're bringing the same scaling power to PostgreSQL with Neki, our sharded PostgreSQL product, and we're looking for Software Engineers to come help build it from scratch.
