Principal Engineer - Cloudforce One

ABOUT THE ROLE Cloudflare is a mission-driven company working to build a better Internet. As a Principal Engineer on Cloudforce One, you will be a key member of our threat operations and research team, responsible for identifying and disrupting cyber threats. You will work closely with external organizations and internal teams to develop operational tradecraft and expand threat intelligence, enabling expedited threat hunting and remediation. WHAT YOU'LL DO As a Principal Engineer, you will be responsible for driving architectural direction and technical strategy across Cloudforce One engineering. You will identify and dismantle technical bottlenecks, legacy patterns, and architectural debt that slow down threat detection and abuse response. You will design and build critical data pipelines and services to collect, enrich, analyze, and expose threat intelligence and abuse signals at massive scale. You will serve as a technical force multiplier across multiple concurrent projects, context-switching between threat intelligence platforms, abuse detection systems, legal response tooling, and customer-facing security products as priorities demand. You will bring a threat-informed perspective to engineering decisions, understanding how adversaries adapt, how detection rules degrade, and how to build systems that stay ahead of evolving attack techniques. You will 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. You will mentor and elevate the engineering talent around you, setting the bar for code quality, system design, operational rigor, and security-first thinking. WHAT YOU'LL NEED To be successful in this role, you will need deep technical expertise in distributed systems architecture and an equally deep understanding of how threat actors operate. You will think like an attacker and build like an engineer who has been burned by production incidents at 3 AM. You will be energized by hard problems, impatient with the status quo, and have a track record of shipping solutions that others said couldn't be done. WHY REMOTE As a remote employee, you will have the flexibility to work from anywhere in the world, allowing you to maintain a healthy work-life balance and work in a setting that suits your needs. BENEFITS * Competitive salary * Comprehensive health plan * Parental leave * Education stipend * Life insurance * Equipment stipend * Flexible schedule
