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. Likewise you will 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.

Engineering teams at Cloudflare operate a Run What You Build model, including ours. We are responsible for the health of our system and participate in our team's on‐call rotation as part of operational responsibilities. 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.

• Make daily progress on assigned engineering tasks, such as designing systems, writing specs, writing and pushing code via git, writing release plans for complex changes, rolling out production releases and working with other teams to coordinate system actions.
• Participate in daily and ad‐hoc team meetings to share progress and collaborate.
• Participate in the team's on‐call schedule to ensure uptime of our production systems.

• Responding to questions from other teams in the Egress team's internal, public chat room.

Role Requirements:

Must‐Have Skills:

• Systems‐level programming experience in Go, Rust, C, or C++. We use Rust extensively, and while experience with the language isn't required a willingness to learn it is.
• 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.
• Strong collaboration and communication skills.
• Experience/interest in HTTP networking and VPN technologies.
• Experience/interest in network performance monitoring and tuning.

Bonus Points:

• Experience participating in an on‐call rotation.

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's 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.
