Software Engineer, Egress (Lisbon / London)
Job Description
Cloudflare is seeking a Software Engineer to join their Egress team, focusing on a crucial aspect of their network-as-a-service infrastructure. This role involves working on cutting-edge network software that powers products like WARP (Cloudflare's Zero Trust platform) and the iCloud Private Relay egress proxy.
The position offers an opportunity to work with a diverse tech stack including Rust, Go, Linux networking, ClickHouse, PostgreSQL, Grafana, and Kubernetes. As part of the team, you'll be involved in all aspects of the software development lifecycle - from system design and documentation to coding, testing, and production deployments.
Cloudflare operates on a "Run What You Build" model, meaning you'll be responsible for the health of your systems and participate in on-call rotations. The role requires strong technical skills in systems programming and networking, with particular emphasis on protocols in Layers 3 and 4 of the OSI Model, HTTP, TLS, and CDN networks.
The company culture emphasizes growth, learning, and working outside one's comfort zone. Cloudflare is committed to building a better Internet, demonstrated through initiatives like Project Galileo (protecting journalism and civil society organizations), the Athenian Project (securing election websites), and 1.1.1.1 (privacy-focused DNS resolver).
This hybrid position is based in either Lisbon or London, requiring at least two days per week in the office. The role offers the opportunity to work on large-scale systems that impact millions of websites and Internet properties worldwide. You'll collaborate with various engineering teams to implement new capabilities and work closely with Network Engineering and SRE teams to optimize performance on Cloudflare's global edge network.
The ideal candidate should be comfortable in a fast-paced environment, value curiosity and empathy, and have a strong foundation in systems programming. While Rust experience is a plus, willingness to learn it is essential. The role provides an excellent opportunity to work on meaningful projects that help shape the future of Internet security and performance.
