About the role
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.
Responsibilities, requirements, fit, evidence and preparation are organized here. The original posting remains available in Source & verification at the end.
What you'll do
- Cloudflare's Trust & Safety team is the frontline defense against platform abuse — phishing, malware distribution, fraud, and content that undermines the safety of the internet. Together, these teams form a unified capability: from tracking an adversary's infrastructure to dismantling it at network scale.
- This role may require flexibility to be on-call outside of standard working hours to address technical issues as needed.
- Drive architectural direction and technical strategy across Cloudforce One engineering, spanning services that run in Kubernetes, on the edge (Workers, D1), and across Cloudflare's global network.
- Identify and dismantle technical bottlenecks, legacy patterns, and architectural debt that slow down threat detection and abuse response — then replace them with systems that are faster, more reliable, and more elegant.
- Design and build critical data pipelines and services to collect, enrich, analyze, and expose threat intelligence and abuse signals at massive scale, helping identify Tactics, Techniques, and Procedures (TTPs) and Indicators of Compromise (IOCs).
- Serve as a technical force multiplier across multiple concurrent projects — you will context-switch between threat intelligence platforms, abuse detection systems, legal response tooling, and customer-facing security products as priorities demand.
- Bring a threat-informed perspective to engineering decisions: understand how adversaries adapt, how detection rules degrade, and how to build systems that stay ahead of evolving attack techniques.
- Collaborate with Threat Intelligence researchers, Trust & Safety analysts, Product, Legal, and other engineering teams to translate complex security and compliance requirements into scalable, production-grade solutions.
- Mentor and elevate the engineering talent around you — set the bar for code quality, system design, operational rigor, and security-first thinking across both organizations.
- Develop and champion agentic AI workflows and AI-assisted development practices that accelerate threat hunting, detection engineering, and abuse investigation.
- Own the operational excellence of the systems you touch, including participation in on-call rotations and incident response.
