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.

Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company.

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 Team

Cloudforce One is Cloudflare’s threat operations and research team, responsible for identifying and disrupting cyber threats ranging from sophisticated cyber criminal activity to nation-state sponsored advanced persistent threats (APTs). Cloudforce One works in close partnership with external organizations and internal Cloudflare teams, continuously developing operational tradecraft and expanding ever-growing sources of threat intelligence to enable expedited threat hunting and remediation. Members of Cloudforce One are at the helm of leveraging an incredibly vast and varied set of data points that only one of the world’s largest global networks can provide. The team is able to analyze these unique data points, at massive scale and efficiency, synthesizing findings into actionable threat intelligence to better protect our customers.

About the Role

Cloudflare is a system spanning the globe, on a mission to make the internet better, safer, and more powerful everyday. To help fulfill this mission, we are seeking a talented Security Engineer to join us in growing our Cloudforce One Organization, where you will be instrumental in building a proactive and threat intelligence-driven approach to protecting Cloudflare and its customers from sophisticated and ever-evolving global threat actors. This position requires an innovative, self-starting, and detail-oriented problem solver with a passion for identifying, tracking, and assessing sophisticated cyber threats.

As a Cloudforce One Security Engineer, you will develop critical services to monitor and disrupt cyber threat activity across multiple platforms, supporting both client requests and proactive internal research. You will serve an integral role in the discovery and analysis of cyber threat adversaries, building pipelines to collect and expose this data for our Cloudforce One analysts and Cloudflare customers. The services you create will help identify Tactics, Techniques, and Procedures (TTPs) of ongoing and ever-evolving cyber attacks to protect our global customer base. Lastly, you will work in close collaboration with team members to develop new and innovative ways to present and interact with Cloudflare's unique insights.

We are hiring for an entry-level software engineer position; however, strong candidates should be able to write reliable code, preferably in Golang or TypeScript. As a member of the team you will be responsible for contributing to and deploying team codebases to coalesce traits of an attack. You will also work both as a self-driven individual contributor and alongside a team to achieve a common goal.

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.

Athenian Project: 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.

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.
