Cloud Data Store (CDS) owns the storage, retrieval, and lifecycle of all workflow data at planet scale. We design the persistence APIs, build storage abstractions that run across cloud vendors, and deliver the observability that lets customers trust their state machines for years. [To see more detail re: the Temporal CDS Eng team, click here] As a Senior Software Engineer, you will get the chance to design, build, and maintain significant portions of our backend functionality for highly scalable, multi-tenant services. You’ll own the custom persistence stack for Temporal Cloud which includes a Write Ahead Log, various metadata stores (Cassandra, etcd), multi-level caches, tiered storage etc.
