Role Summary

The Egress team was formed to own a very important aspect of Cloudflare's network‑as‑a‑service: egress connectivity for our vast portfolio of products. As a member of the Egress team, you will be a key technical contributor to a cutting edge network software infrastructure used by a growing number of Cloudflare products to connect to any destination from Cloudflare's network. Among the products powered by this technology is WARP, our Zero Trust platform, and Cloudflare's egress proxy for the iCloud Private Relay product. You will work closely with various Engineering teams to translate their requirements into new capabilities on the platform and partner with Network Engineering and SRE to ensure that the technology makes the best use of Cloudflare's world‑class edge network. You will participate in all stages of the software development lifecycle, from designing and documenting systems, to writing code and automated tests, to planning, managing, and monitoring production software deployments. You will work with a wide range of technologies and programming languages, including Rust, Go, Linux networking, ClickHouse, PostgreSQL, Grafana, Kubernetes, and more. Because you’ll be solving problems of massive scale and significance, you are a growth‑oriented individual who enjoys being outside of your comfort zone. You are comfortable in a fast‑paced but sensible work environment. You value curiosity and empathy and lead with these values.

  • Participate in the team’s on‑call schedule to ensure uptime of our production systems.
  • Investigate customer issues that are escalated to the Egress team for triage and resolution.
  • Respond to questions from other teams in the Egress team’s internal, public chat room.
  • Use AI‑powered tools and systems as part of your daily workflow to analyze and extend codebases, introspect production systems and datasets, and accelerate problem‑solving.

Must‑Have Skills

  • Programming experience in Go or Rust and a desire to improve your skills in both.
  • A solid grasp of networking protocols in Layers 3 and 4 of the OSI Model.
  • Knowledge of HTTP, TLS, and CDN networks.
  • Experience in implementing secure and highly‑available distributed systems.
  • Strong ability to debug issues in complex systems.

  • Experience building tools and APIs.
  • Experience with monitoring, alerting, and debugging large‑scale distributed systems.
  • Experience participating in an on‑call rotation.
  • Experience using AI‑assisted development tools (e.g., code completion, codebase analysis, log/data exploration) in a professional setting.
