About the Role
The R2 Gateway team owns the request-facing layer of R2, Cloudflare's object storage platform. This layer includes the S3-compatible API gateway that handles all object operations (put, get, list, delete). The team is responsible for evolving the gateway to keep pace with R2's rapid growth, managing authentication, request routing, rate limiting, and coordination between clients and R2's storage and metadata layers, while maintaining S3 API compatibility and ensuring low-latency, highly available access at a global scale. You will work at the intersection of large-scale distributed systems, storage infrastructure, and edge computing, building critical request-path systems.
Responsibilities
- Design, implement, and operate the S3-compatible API gateway, ensuring correctness, low latency, and S3 API compatibility.
- Build and operate production services on Cloudflare Workers and Kubernetes for high-throughput request traffic with strong availability and durability.
- Own the end-to-end request path, including authentication, authorization, routing, rate limiting, and error handling.
- Manage interfaces between the gateway and R2's storage and metadata layers.
- Own projects from design through implementation, testing, deployment, and production monitoring.
- Continuously improve gateway reliability, performance, and observability.
- Quickly learn unfamiliar and legacy code, and reduce operational toil.
- Participate in on-call rotations, drive incident resolution, and write postmortems.
- Use AI tools extensively to accelerate development, debugging, and operational tasks.
- Collaborate with storage infrastructure, metadata, networking, and other platform teams on API contracts, capacity planning, and cross-cutting initiatives.
Requirements
- Experience building or operating large-scale distributed systems on the request path with strong latency and reliability requirements.
- Experience designing and operating high-throughput APIs, including authentication, routing, rate limiting, and backward-compatible API evolution.
- 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 the S3 API surface, or with Cloudflare Workers, Durable Objects, or edge computing platforms, is a strong plus.
- This position may require access to information protected under U.S. export control laws, and any offer of employment may be conditioned on authorization to receive such technology without sponsorship.
