The opportunity

R2 is Cloudflare's object storage platform, offering developers durable, reliable storage with zero egress fees that integrates seamlessly with Cloudflare's global network and Developer Platform. The R2 Gateway team owns the request-facing layer of R2 — the S3-compatible API…

What you'll do

  • Design, implement, and operate the S3-compatible API gateway that serves: every R2 operation, ensuring correctness, low latency, and compatibility with the S3 API surface.

  • Build and operate production services on Cloudflare Workers and Kubernetes: that handle high-throughput request traffic with strong availability and durability guarantees.

  • Own the request path end to end: authentication, authorization, routing, rate limiting, and error handling — and the interfaces between the gateway and R2's storage and metadata layers.

  • Own projects end to end: from design docs through implementation, testing, deployment, and production monitoring.

  • Continuously improve the reliability, performance, and observability of the: gateway; ramp quickly into unfamiliar and legacy code paths and reduce operational toil.

  • Participate in on-call rotations, drive incident resolution, and write: postmortems that raise reliability standards.

What they're looking for

  • 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, metadata, networking, other: platform teams) to coordinate API contracts, capacity planning, and cross-cutting initiatives.
