Build high-throughput distributed data delivery, ClickHouse analytics, and retrieval APIs at Cloudflare scale
Cloudflare's Data Org owns the entire data lifecycle — ingestion, delivery, storage, and retrieval — for systems handling over a billion events per second, spanning a Go-based delivery pipeline, a ClickHouse-powered analytical database platform, and customer-facing GraphQL/log/alerting products. This interview tests distributed systems and database fundamentals, Go proficiency, SQL/database internals, and observability at high cardinality. Strong candidates show they can reason about bottlenecks, scale, and reliability in systems that are customer-facing and always-on.
