About Us

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. Internet properties powered by Cloudflare all have web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company.

Available Locations

Austin, TX | London, UK | Lisbon, Portugal

About The Role

The CNI team builds and operates the systems that let Cloudflare's enterprise customers connect their networks directly to Cloudflare through private, dedicated interconnects — rather than traversing the public Internet. The product, Cloudflare Network Interconnect (CNI), supports various interconnect types across hundreds of locations worldwide. These systems underpin Magic Transit, Cloudflare WAN, Zero Trust, and application security for some of Cloudflare's largest customers.

What You'll Do

As a member of the team you will build and extend the systems that provision, monitor, and orchestrate private network interconnects at scale. You will collaborate with Product Management, Network Engineering, and Infrastructure teams on ambitious initiatives to connect enterprise customers directly to Cloudflare's global network.

Responsibilities

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, PostgreSQL, Prometheus, Kubernetes, Linux networking, network operating systems, and BGP routing, among others.

Our team at Cloudflare operates under a "Run What You Build" model. This means we are responsible for the health of our systems and actively participate in our team's on-call rotation as part of our operational duties.

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.

Desirable Skills, Knowledge, and Experience

• Systems-level programming experience in Rust, Go, C, or C++.
• Understanding of IP networking fundamentals: BGP, Layer 3 routing, and how physical and virtual interconnect technologies work (cross-connects, VLANs, overlay tunnels).
• Experience building, deploying, and debugging distributed systems.
• Experience participating in an on-call rotation for services with direct customer impact.
• Willingness to adopt and integrate AI tools and systems into your workflow.
• Strong collaboration and communication skills.

Bonus Points

• Hands‑on experience with BGP configuration, route policy, or peering operations.
• Experience building provisioning or automation systems for network infrastructure.
• Familiarity with network inventory and IPAM systems (e.g., NetBox).
• Experience with cloud provider networking (AWS Direct Connect, GCP Partner Interconnect, Azure ExpressRoute).
• Knowledge of GRE, VXLAN, or other overlay/tunnel technologies.
• Experience with Kubernetes‑based service deployments and CI/CD pipelines.
• Experience with telemetry/observability platforms (Prometheus, Grafana, ClickHouse, Elasticsearch).
• Experience using AI‑assisted development tools (e.g., code completion, codebase analysis, log/data exploration) in a professional setting.

Compensation

Compensation may be adjusted depending on work location.

• For Portugal based hires: Estimated annual salary is between €54,000 - €75,000

Equity

This role is eligible to participate in Cloudflare’s equity plan.

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 is 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.
