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.
Desirable Skills, Knowledge, and Experience
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.
What Makes Cloudflare Special?
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.
