Software Engineer, Storage
Software Engineer on the Storage team owning the data layer (databases, caches, scaling strategies) that underpins all Cursor products. Design multi-database architectures, build query guardrails, define storage best practices, and own cache infrastructure for reliability and growth.
About the job
Responsibilities
- Own the data layer underpinning every product surface: databases, caches, and strategies for provisioning, querying, and scaling data stores.
- Design and execute a robust, multi-database topology for growth.
- Design next-generation data architecture: evolve storage layer into a partitioned, resilient topology.
- Build query attribution and guardrails: instrument database queries by service, catch bad patterns before production, prevent shipping problematic queries without review.
- Define "when to use what" strategy for data stores: provide clear guidance and golden pathways for teams to select right engine for workloads.
- Own cache infrastructure end-to-end: reliability, capacity planning, and patterns for product teams.
Requirements
- Deep experience with relational databases at scale, especially Postgres, MySQL, or similar OLTP systems.
- Experience tackling database sharding, migration, or decomposition problems in production.
- Understanding of tradeoffs between different storage engines and ability to guide teams on workload choices.
- Focus on operational excellence: backups, monitoring, query performance, capacity planning.
- Strong software engineering fundamentals and enjoyment in building systems other engineers depend on.
