About Us

At Cloudflare, we have our eyes set on an ambitious goal: to help build a better Internet. Today the company runs one of the world's largest networks that powers more than 10 trillion requests per month. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare have all 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 recognized by the World Economic Forum as a Technology Pioneer and named to Entrepreneur Magazine's Top Company Cultures list.

We realize people do not fit into neat boxes. We are looking for curious and empathetic individuals who are committed to developing themselves and learning new skills, and we are ready to help you do that. We cannot complete our mission without building a diverse and inclusive team. We hire the best people based on an evaluation of their potential and support them throughout their time at Cloudflare. Come join us!

About the Department

We build and run the internal tools that builds and runs our software. The Engineering Team is split into two groups: one handles product development and the other handles operations. Product development covers both new features and functionality and scaling our existing software to meet the challenges of a massively growing customer base. The operations team handles one of the world's largest networks with data centers in 165+ cities worldwide.

What you'll do

In this role you will work on Spectrum, a new product that extends Cloudflare's security and performance beyond web traffic. As an engineer on the Spectrum team, you will be responsible for building and maintaining the technologies and systems that comprise Spectrum, both in our high-performance global edge network and in our centralized microservice cluster.

Examples of software systems that you'll be working with include:

* A Layer 4 proxy running at Cloudflare's Edge, responsible for making any and all TCP/UDP traffic from clients to The Edge as fast and secure as possible.
* A global data pipeline that processes hundreds of thousands of events per second, used to deliver insights about Spectrum to customers and internal teams alike.
* REST APIs that enable customers to quickly and easily protect their services via Spectrum.

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 Go, Rust, Python, REST APIs, ClickHouse, Kafka, Salt, SQL, Grafana, Docker, Kubernetes, and Marathon.

Other responsibilities include:

* Collaborating with internal teams (security, network engineering, SRE, product management) to design effective and scalable solutions to difficult technical problems.
* Reviewing work from your peers throughout all stages of the development lifecycle.
* Working with our support teams to ensure customer delight.
* Mentoring team members to help bring out their best work.
* Representing the team within the company through blogging and tech talks.

Because you'll be solving problems of massive scale and significance, and shaping the future of performance on the Internet, you are a growth-oriented individual who enjoys being outside of your comfort zone. You are comfortable in a fast-paced but sane work environment.

Examples of desirable skills, knowledge and experience

* Programming experience in Go, Rust, C, or C++.
* Working knowledge of modern Unix/Linux development and runtime environments.
* Strong low level debugging skills.
* A solid grasp of networking protocols in any of Layers 3-7 of the OSI Model.
* Experience in implementing secure and highly-available distributed systems.
* Strong ability to debug issues in complex systems.
* Strong interpersonal and communication skills. Curiosity and empathy are coveted traits here!

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: We equip politically and artistically important organizations and journalists 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.

Project Athenian: We created 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.

Path Forward Partnership: Since 2016, we have partnered with Path Forward, a nonprofit organization, to create 16-week positions for mid-career professionals who want to get back to the workplace after taking time off to care for a child, parent, or loved one. We released 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 policy and ensure that no user data is sold to advertisers or used to target consumers.
