R2 API Gateway Engineer (Edge/Storage)

Webhosting; Austin, Northern (TX, KY); Hybrid; USD 180,000 - 240,000; Full time

Job summary

Cloudflare in Austin, TX, offers a hybrid role on the R2 gateway team building the S3‑compatible API gateway inside Cloudflare’s edge network. You will design, implement, and operate high‑throughput services, ensuring strong latency, reliability, and compatibility with the S3 API surface.

Join a team operating at the intersection of distributed systems and edge computing, using AI tooling to accelerate development, debugging, and operations.

Qualifications

• Strong programming skills in Rust, TypeScript, Go, or similar languages.
• 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.
