Software Engineer, Storage, Distributed Caching at DoorDash

DoorDash connects customers with local businesses for delivery, from restaurants to grocery, retail and its own DashMart stores. The Storage organization builds and operates the online stateful systems and abstractions that DoorDash Engineering depends on: reliable, efficient, secure, and easy to use. Within Storage, the Distributed Caching team owns every caching offering at DoorDash end to end, including ElastiCache (Redis/Valkey), Boulder (our KVRocks-based key-value store for high-QPS feature serving

Key responsibilities

• Own high-leverage caching and locking services with direct, measurable customer impact: cost, latency, and reliability at multi million QPS scale
• Build and scale Boulder, our KVRocks backed key-value store, including compaction, sharding, and domain isolation
• Re-platform the Distributed Lock Service onto a strongly consistent backend with sharding
• Contribute to the standardized smart caching client that bakes in failover, retry
• Diagnose and resolve production issues that span cache invalidation storms, replication lag, hot shards, and noisy-neighbor contention
• Collaborate closely with the teams that build on top of caching, including Taulu, ML Platform, and product engineering across DoorDash, Wolt

Requirements

• 6+ years of full-time experience designing, building, and operating distributed, stateful systems in production
• Proficient in Go, or Java/Kotlin with deep expertise in concurrency, distributed systems, and production-grade backend services
• Hands-on experience with distributed caching technologies (Redis/Valkey, Memcached, or similar) and understand their failure modes: replication lag
• Understand distributed systems fundamentals: consistency models, sharding and partitioning, replication, and consensus
• Built or operated systems that require careful capacity planning and cost discipline at scale, and you default to right-sizing over over-provisioning
• Thrive in an execution-driven environment with a broad ownership area and a proven track record of shipping reliable infrastructure end to end

Location and schedule

• Onsite in San Francisco, California
• You must be located in San Francisco, Seattle, or the New York Metro Area for this hybrid position. You will report to the Engineering Manager on the Distributed Caching team within the Storage organization
