Systems Engineer, R2 Gateway

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.

R2 is growing rapidly, and the gateway must evolve to keep pace. The team is responsible for the API surface that handles authentication, request routing, rate limiting, and coordination between clients and R2's storage and metadata layers — all while maintaining strict compatibility with the S3 API and delivering low-latency, highly available access at global scale.

You'll be joining a team that operates at the intersection of large-scale distributed systems, storage infrastructure, and edge computing — building request-path systems that need to be correct, fast, and reliable on every single call.

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.

We’re not just a highly ambitious, large-scale technology company. We’re a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.

Project Galileo: Since 2014, we've equipped more than 2,400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare’s enterprise customers--at no cost.

Athenian Project: In 2017, we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration. Since the project, we've provided services to more than 425 local government election websites in 33 states.

1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released. Here’s the deal - we don’t store client IP addresses never, ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.
