Software Engineer, Storage

About the Role

As a Software Engineer on the Storage team, you'll own the data layer that underpins every product surface: the databases, caches, and the strategy for how teams provision, query, and scale their data stores.

Millions of developers depend on Cursor every day, and the future of our storage architecture is one of the highest-leverage problems at the company: get it right, and every team ships faster, every product surface gets more reliable, and we can scale to meet explosive demand. You'll design and execute the path to a robust, multi-database topology built for that growth.

Example Projects

• Designing the next-generation data architecture: evolving our storage layer into a partitioned, resilient topology that keeps pace with rapid growth.
• Building query attribution and guardrails: instrumenting every database query by service, catching bad patterns before they hit production, and making it impossible to ship problematic queries without review.
• Defining the "when to use what" strategy for data stores: creating clear guidance and golden pathways so every team picks the right engine for their workload without second-guessing.
• Owning cache infrastructure end-to-end: reliability, capacity planning, and patterns that let product teams move fast without worrying about cache correctness.

Qualifications

• Deep experience with relational databases at scale, especially Postgres, MySQL, or similar OLTP systems.
• Experience tackling database sharding, migration, or decomposition problems in production environments.
• Understanding of tradeoffs between different storage engines to help teams make the right choices for their workloads.
• Focus on operational excellence: proactive thinking regarding backups, monitoring, query performance, and capacity planning.
• Strong software engineering fundamentals and passion for building systems that other engineers depend on.

Interview Process

• 2–3 short technical interviews.
• Onsite in office featuring a small project, idea discussions, and meeting the team.
