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. About the Role Cloudflare runs one of the world's largest networks, and every API call that configures it, from any customer, integration, or internal service, starts by proving who is calling and what they're allowed to do. The IAM team owns the authentication and authorization systems behind that: the identity layer of the Control Plane operating at global scale. Our surface spans things like login and SSO, OAuth and API tokens, account membership, roles and permissions, and SCIM provisioning. We're hiring a hands-on senior engineer to work on correctness-critical, high-throughput, highly resilient services. You'll own surfaces end-to-end, chase down hard problems with high agency, and improve systems while they're serving production traffic. Responsibilities • Feature development : design and build high-throughput, low-latency IAM capabilities that power both customer-facing and internal service APIs. • System evolution : contribute to the design and evolution of our authentication and authorization systems into modern, distributed, and edge-capable architectures. • API and system design : translate product and security requirements into robust, well-structured APIs and technical specifications in collaboration with Product, Security, and UX teams. • Engineering excellence : maintain a high bar through thorough code reviews, technical design documents, and collaborative problem-solving. • Operational stewardship : own the reliability of the platform under constant load, ensuring observability and resilience are built into every service. • AI-assisted development : use AI tools throughout your workflow, from code generation to debugging, and bring the judgment to know when to trust them. Desirable Skills, Knowledge, and Experience These are examples of what a strong candidate brings: • Professional Experience: 5-8 years building and operating production systems at scale. • Identity Domain Knowledge: Working knowledge of identity protocols and models (OAuth 2.0, OID
