## Description

At Cloudflare, were not looking for people who wait for a polished roadmap; were 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 youre 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, youll fit right in., Cloudflare is looking for a Software Engineer to design, build, and operate the services behind Cloudflare for SaaS. You will work primarily on backend services and RESTful APIs in Go and other languages, modernize legacy control-plane workflows, and improve the reliability and scalability of production systems. You will collaborate with product managers and engineers across Cloudflare, write clear technical specifications, review code, instrument services, and help diagnose and resolve operational issues.

What You'll Do

 * Design, build, and operate reliable backend services and APIs for managing customer domains and their configuration.
 * Evolve the control plane to support tens of millions of customer domains without sacrificing correctness, availability, or API performance.
 * Improve certificate and domain lifecycle workflows, including onboarding, validation, renewal, migration, and safe deletion.
 * Model ownership and shared state carefully so changes remain consistent across distributed services and configuration stores.
 * Build useful observability, alerts, and operational procedures, and participate in debugging and incident response.
 * Collaborate across engineering and product teams, document designs and tradeoffs, and review the work of fellow engineers.
