Technical Support Engineer Intern (July to December 2026)

About the role

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. Available location(s): Singapore Why Cloudflare? Cloudflare is the fabric of the modern internet, securing and accelerating approximately 20% of all HTTP traffic across 330 cities worldwide. Here, you aren't just working on a siloed app; you are operating at the epicenter of the AI revolution, helping the world's most innovative startups deploy LLMs and vector databases at the edge. From pioneering post-quantum cryptography to serving as the "Internet's First Responder" during global BGP leaks and Zero-Day vulnerabilities, we provide a front-row seat to the future of compute.

This is a high-impact, cross-functional role where your insights don't just solve tickets; they actively shape the development of Cloudflare's future product suite. Why This Internship? Forget the "intern" stereotypes-this is a 12-week intensive designed to turn students into world-class engineers. You will skip the coffee runs and dive straight into rigorous, hands-on training that bridges the gap between classroom theory and massive-scale infrastructure. Through close mentorship and job-shadowing, you'll tackle the same complex troubleshooting as our full-time staff, gaining deep proficiency in networking, security, and serverless compute. You will leave Cloudflare not just with a line on your resume, but with a battle-tested portfolio of skills that will set you apart in the global tech talent pool. What You'll Do: Technical Impact & Growth Deep-Dive Investigations: Move beyond surface-level fixes.

High-Velocity Learning: Experience the thrill of a high-growth environment where new features ship daily and the scale is measured in petabytes.
