About the role

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 gateway that every object put, get, list, and delete flows through. When a customer or application talks to R2, they talk to the systems we build and operate.

Stay in Aptiora while you decide.

Responsibilities, requirements, fit, evidence and preparation are organized here. The original posting stays available for final verification.

Your work

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.
  • 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.

About Cloudflare

Verified

We're not looking for people who wait for a polished roadmap. We're looking for builders — people who spot the "normalized" problem everyone else has learned to live with and have the curiosity and drive to fix it. Our culture is built on iteration, leveraging AI to move faster and sharing every improvement across the team. If you value curiosity over bureaucracy and see AI as a partner in solving hard problems, you'll fit right in.
