About the role

Key responsibilities & impact

Design and implement features in a metadata system, backed by a distributed SQL DB, that serves every R2 API operation, ensuring correctness, performance, and compatibility with the S3 API surface.
Build and operate production services on Cloudflare Workers and Kubernetes that handle high throughput metadata operations with strong consistency and durability guarantees.
Own the schema, data model, and query patterns for a metadata layer managing billions of objects across multiple distributed database clusters.
Own projects end to end; from design docs and schema changes through implementation, testing, deployment, and production monitoring.
Participate in oncall rotations, drive incident resolution, and write postmortems that improve reliability.
Use AI tools extensively to accelerate development, debugging, and operational tasks. We expect engineers to leverage AI as a core part of their workflow.
Collaborate across teams (storage infrastructure, networking, other platform teams) to coordinate capacity planning, API contracts, and cross cutting initiatives.
