About the role
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, requirements, fit, evidence and preparation are organized here. The original posting stays available for final verification.
What you’ll do
- 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 PostgresSQL. 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.

We're not looking for people who wait for a polished roadmap. We're looking for builders — people who spot the "normalized" problem everyone else has learned to live with and have the curiosity and drive to fix it. Our culture is built on iteration, leveraging AI to move faster and sharing every improvement across the team. If you value curiosity over bureaucracy and see AI as a partner in solving hard problems, you'll fit right in.
