- 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.
As a Senior Software Engineer on the IPC team, you'll be at the forefront of Cloudflare's core infrastructure. This isn't just about writing code; it's about shaping the future of how our distributed systems communicate. You will serve as a key technical leader, responsible for designing and implementing the next generation of our communication protocols and their associated libraries.
Your work will directly enable other engineering teams to build innovative services on top of a robust, high-performance foundation. This role requires a unique blend of deep technical expertise and the ability to influence others. You'll work across teams to define new features, ensure operational excellence, and drive the adoption of your solutions.
Your primary focus will be on:- Architecting and building new features for our high-performance communication protocol.
- Championing operational excellence by defining and measuring key metrics like Service Level Objectives (SLOs) and error rates.
- Driving cross-team collaboration to ensure our communication platform meets the needs of teams across the organization.
We are looking for seasoned professionals with a strong background in software architecture and distributed systems.- Deep expertise in Rust, with a history of building complex, production-grade applications.
- Strong competencies in computer science, including a solid understanding of algorithms, data structures, and concurrency control.
- Experience with performance engineering and a proven track record of optimizing high-throughput, low-latency systems.
- Excellent communication and collaboration skills to drive consensus and coordinate with diverse engineering teams.
- A passion for continuous improvement in both operations and product development.
Bonus Points- A deep understanding of web protocols and web servers.
- Experience with distributed systems architecture.
- Knowledge of web security issues and industry standards.
- Familiarity with Prometheus for monitoring and alerting.
Most importantly, we're seeking a builder-someone who is excited by the challenge of working on a system at a scale few companies ever reach. Join us in our mission to build a better internet for everyone!
