R2 Gateway Engineer — Edge API & Storage

Cloudflare; Austin (TX); Hybrid; USD 140,000 - 190,000; Full time

Job summary

Cloudflare is seeking a software engineer to help shape R2, our S3-compatible object storage gateway, operating at the edge with low latency and high durability. You will design, implement, and run the API surface that every R2 operation uses, collaborating with teams across storage, networking, and platform.

Join a team building at Cloudflare Workers and Kubernetes, embracing AI-powered tooling to accelerate development and incident response, while delivering reliable services to customers

Qualifications

• Strong programming skills in Rust, TypeScript, Go, or similar languages.
• 3-4 years of experience building or operating large-scale distributed systems on the request path, with strong latency and reliability requirements.
• Familiarity with cloud infrastructure concepts such as object storage, HTTP/API gateways, edge computing, or service-oriented architectures.
• Experience designing and operating high-throughput APIs — 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.

Responsibilities

• 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.
