About the role

Senior role designing and operating the metadata layer for Cloudflare's R2 object storage platform, focusing on distributed metadata systems, scalability, reliability, and performance at global scale. Hybrid role with locations in Austin, TX and London, UK.

Responsibilities

  • 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.

Qualifications

  • Strong programming skills in TypeScript, Go, or similar languages.
  • Experience with distributed databases; schema design, query optimization, indexing strategies, and understanding consistency/performance tradeoffs at scale.
  • Experience building or operating large scale distributed systems with strong reliability requirements.
  • Familiarity with cloud infrastructure concepts such as object storage, edge computing, or service oriented architectures.
  • Understanding of reliability and observability practices: monitoring, alerting, performance tuning, and incident response.
  • Strong written and verbal communication skills; ability to explain technical decisions clearly and coordinate across teams.
  • Comfortable working with AI coding tools as part of a daily development workflow.
  • Experience with Cloudflare Workers, Durable Objects, or edge computing platforms is a strong plus.
