At Cloudflare, we are on a mission to help build a better Internet. Today the company runs one of the world's largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code.
The Team
Cloudflare's CDN group provides the core infrastructure for services at the edge, a massive distributed system where milliseconds matter. As part of this group, the Inter-Process Communication (IPC) team is responsible for building and maintaining the high-performance communication layer that connects all the different services. Our team's mission is to ensure this communication is as reliable, secure, and fast as humanly possible. We believe that Rust is the right tool for this challenge, and our entire codebase is built with it.
The Role
As a Senior Engineer/Architect on the Platform team, you will be instrumental in building the next generation of our communication strategy. This is more than just maintaining a system; it's about innovating and building a platform that empowers teams across the company. You will coordinate efforts across multiple teams to design, build, and deploy new features that enhance the availability, safety, and reliability of our edge network. This is a unique opportunity to sit at the nexus of Cloudflare's operations, influencing how millions of people experience the internet.
Your primary focus will be on building a high-performance platform with a keen eye on operational excellence. This includes defining and implementing clear Service Level Objectives (SLOs), monitoring key metrics, and managing error rates to ensure a robust and reliable system.
