Software Engineer, Cloudforce One

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.

At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a “normalized” problem and the AI‑native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you’re the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you’ll fit right in.

Role Summary

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. As a Software Engineer on this team, you will own the entire software development lifecycle—from design and architecture to deployment and monitoring—for systems that serve both threat disruption and legal response efforts. You will be responsible for translating complex legal and security requirements into robust, scalable, and high‑performance applications that have a direct impact on making the internet better, safer, and more powerful every day.

Responsibilities

While the majority of our services are now written in Golang and TypeScript, you will also work with technologies such as Rust, Kafka, Redis, Kubernetes, Terraform, Temporal and PostgreSQL. We also pride ourselves in dogfooding our own products and services so you will be extensively working with Cloudflare’s developer platform as well. We are looking for great engineers regardless of experience with any of these specific technologies. This role may require flexibility to be on‑call outside of standard working hours to address technical issues as needed.

• Design, build, run, and scale distributed tools and services that support both cyber threat disruption and platform abuse efforts.
• Develop critical data pipelines and services to collect, analyze, and expose threat intelligence data for Cloudforce One analysts and Cloudflare customers, helping to identify Tactics, Techniques, and Procedures (TTPs) and Indicators of Compromise (IOCs).
• Collaborate closely with Threat Intelligence, Trust & Safety, Legal, and Product teams to understand goals and translate complex technical requirements into elegant, scalable solutions.
• Improve system design and architecture to ensure stability, performance, and maintainability of both internal and customer‑facing compliance and security services.
• Analyze, communicate, and help prioritize complex technical concepts across teams.
• Ongoing monitoring and maintenance of production services, including participation in on‑call rotations.
• Mentor and guide other developers in the team, helping to build collective technical expertise and promote best practices for writing well‑tested, modular, and reusable code.
