AI SummaryDropbox is seeking an experienced infrastructure software engineer to build and operate mission-critical metadata databases serving millions of users and hundreds of internal services. The role centers on distributed systems design, strongly consistent storage, replication, consensus, caching, and production reliability. The engineer will write performance-critical Go and Rust, participate in on-call operations, and contribute to architecture reviews and postmortems. Success requires deep distributed-systems expertise, strong debugging skills, and effective collaboration with infrastructure and product teams. ## Role DNA A quick view of the complexity, pace, ownership and collaboration implied by the job description. ### Job Complexity 5/5EasyHard ### Pace & Pressure 4/5RelaxedFast-paced ### Autonomy Level 4/5GuidedFull ownership ### Communication Load 4/5IndependentCollaborative AI insightThis is a senior infrastructure role involving highly available, strongly consistent distributed databases in the live path of user operations.

Data would be partitioned carefully, each shard would maintain quorum-based replicas across failure domains, and clients would route writes through the current leader. I would also define backpressure, retry, repair, and observability mechanisms so degraded conditions are detected and handled without compromising correctness. What trade-offs would you evaluate when choosing between an LSM tree and a B-tree for a storage engine? I would evaluate read/write workload shape, tail-latency requirements, storage amplification, range-query behavior, and operational complexity. LSM trees generally optimize high write throughput through sequential writes but require compaction management and can increase read amplification. B-trees can provide more predictable point and range reads, though random-write costs may be higher depending on the storage medium and implementation. Describe how you would investigate a sudden increase in p99 latency in a distributed database service. I would first correlate the latency increase with traffic, deployments, error rates, resource saturation, garbage collection, disk and network metrics, and replica health. I would use tracing and request-level breakdowns to isolate whether the delay is in routing, consensus, storage I/O, cache misses, lock contention, or downstream dependencies. After mitigating the immediate issue, I would document the root cause, add targeted alerts or capacity safeguards, and validate the fix through load testing. How do you safely evolve a replication or consensus component used by many production services? I would make compatibility and rollback the primary design constraints. The change should be introduced behind feature flags or versioned protocols, tested through failure injection and mixed-version clusters, and rolled out incrementally with explicit health and correctness gates. I would also prepare operational runbooks, monitor replication lag and quorum behavior closely, and retain a tested rollback path. How would you work with product teams to turn future metadata use cases into an infrastructure roadmap? I would gather concrete workload characteristics such as access patterns, consistency needs, growth forecasts, latency objectives, and failure tolerance. I would translate those needs into capacity, architecture, and reliability gaps, clearly communicate trade-offs, and prioritize work based on customer impact and risk. The resulting roadmap would distinguish immediate reliability commitments from longer-term platform investments and be revisited as product assumptions change. ### Role Description As a Software Engineer on the Metadata team, you’ll build and operate the large-scale distributed databases that every Dropbox service depends on. Metadata systems are mission-critical, in the live path for all user operations and must meet stringent requirements for latency, durability, and transactional consistency. You’ll design and evolve the core infrastructure that manages Dropbox’s databases at scale, enabling fast, reliable access to data for millions of users and hundreds of internal services. This work spans distributed systems, replication, caching, and transactional database systems. You’ll collaborate closely with engineers across Infrastructure and Product teams to ensure the metadata layer meets business needs and continues to scale with Dropbox’s growth. This is an opportunity to leverage your expertise in distributed systems and grow into broader technical leadership.
