The role

Summary

As a Software Engineer on the Storage team at Cursor, you'll own the data layer infrastructure supporting millions of developers using an AI-powered coding platform. This role focuses on designing scalable multi-database architectures, implementing query attribution systems, and managing cache infrastructure for a rapidly growing developer tool. You'll need deep experience with relational databases like PostgreSQL and MySQL at scale, plus proven expertise in database sharding, migration, and operational excellence.

What you'll do

Design Next-Generation Data Architecture: Architect and evolve the storage layer into a partitioned, resilient topology supporting millions of concurrent users. Design multi-database strategies that enable rapid scaling while maintaining system reliability and performance across all product surfaces.
Implement Query Attribution and Guardrails: Build comprehensive query monitoring systems that instrument database queries by service and detect problematic patterns before they reach production. Create review workflows and automated safeguards that prevent performance-degrading queries from being deployed.
Define Data Store Selection Strategy: Establish clear guidance and golden pathways for engineering teams to select appropriate database engines for their specific workloads. Document tradeoffs between storage solutions and build decision frameworks that eliminate guesswork and standardize infrastructure choices across teams.
Own Cache Infrastructure End-to-End: Design, deploy, and maintain reliable cache systems including capacity planning, performance optimization, and correctness guarantees. Build patterns and abstractions that allow product teams to leverage caching without managing complexity or worrying about cache invalidation issues.
Collaborate on Database Operations and Scaling: Partner with infrastructure and product teams to implement database sharding strategies, handle migrations, and manage service decomposition. Handle backups, disaster recovery, monitoring, and capacity planning with proactive operational excellence.
Drive Infrastructure Standards and Best Practices: Establish monitoring frameworks, alerting systems, and performance baselines for the storage infrastructure. Create documentation, runbooks, and training materials that enable other engineers to work effectively with storage systems and troubleshoot issues independently.

What we look for

Technical

Relational Database ExpertiseDeep production experience with PostgreSQL, MySQL, or similar OLTP systems at scale. Proven track record optimizing complex queries, managing indexes, and tuning database performance for high-throughput environments supporting millions of operations.
Database Sharding and ScalingHands-on experience designing and implementing database sharding strategies, horizontal scaling patterns, and data decomposition approaches. Demonstrated ability to handle migration challenges and maintain consistency during infrastructure evolution.
Cache and Storage SystemsPractical expertise with caching layers (Redis, Memcached, or similar), understanding cache invalidation strategies, and implementing reliable cache infrastructure. Knowledge of tradeoffs between different storage engines and caching approaches for various workload patterns.
Systems Design and ArchitectureStrong systems design fundamentals with ability to architect resilient, scalable distributed systems. Experience designing for fault tolerance, consistency, availability, and operational simplicity in production environments.
Monitoring and ObservabilityProficiency building and implementing comprehensive monitoring, alerting, and observability systems for databases and infrastructure. Experience using APM tools, query profilers, and performance analysis to identify and resolve bottlenecks.

Education

Bachelor's Degree in Computer Science or Related FieldFormal education in Computer Science, Computer Engineering, or equivalent practical experience demonstrating strong foundational knowledge in algorithms, data structures, and system design principles.

Experience

5+ Years Backend/Infrastructure EngineeringMinimum five years of professional software engineering experience with significant focus on backend systems, database architecture, or infrastructure engineering at scale.
Production Database OperationsProven experience tackling real production challenges including database troubleshooting, performance optimization, incident response, and capacity management in high-traffic environments.
Cross-Team Infrastructure CollaborationTrack record of working effectively with multiple engineering teams to design and implement shared infrastructure. Demonstrated ability to communicate complex technical concepts and build consensus around architectural decisions.

Skills

Required skills

PostgreSQLAdvanced proficiency with PostgreSQL including query optimization, indexing strategies, configuration tuning, and operational management at scale.
MySQL/MariaDBDeep experience with MySQL or MariaDB including understanding of storage engines, replication, high availability configurations, and performance tuning.
Database Sharding and Horizontal ScalingHands-on experience implementing partitioning strategies, managing shard keys, and handling distributed query execution across sharded datasets.
Redis or MemcachedPractical expertise deploying and operating distributed cache systems, implementing cache strategies, and debugging cache-related issues in production.
