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. In our Singapore hub, you'll join a culture of radical transparency and technical excellence where we prioritize a fast, private, and secure internet for everyone.

The Mission

As a Technical Support Engineer Intern, you are the bridge between global customers and our internal product engineers. You will act as a technical investigator, translating complex puzzles into actionable solutions for everyone from solo developers to Fortune 500 enterprises. Your goal is to ensure the "Edge" remains reliable by diagnosing real-world use cases and providing direct feedback to our product teams. 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. You will troubleshoot complex networking, security, and performance issues using the same tools our core engineers use.
• The AI Frontier: Help customers operate and optimize Cloudflare Workers AI, exploring how LLMs and vector databases operate at the edge.
• Master the Stack: Gain battle-tested experience with Layers 3, 4, and 7. You'll live in the command line using curl, dig, mtr, and openssl to diagnose global traffic patterns.
• Cross-Functional Exposure: Beyond support, you'll shadow senior engineers, contribute to product runbooks, and provide direct feedback to Product Management to shape the future of our features.
• High-Velocity Learning: Experience the thrill of a high-growth environment where new features ship daily and the scale is measured in petabytes.
• Available for a full-time minimum 12-week internship, working from our Singapore office 3-5 days a week between July - December.

What We're Looking For

• The "Curiosity" Factor: You're the person who doesn't just want to fix a bug. You want to know why it happened.
• Internet Fundamentals: You understand the OSI model and have a healthy obsession with how packets move from Point A to Point B.
• Scripting Mindset: You're comfortable (or eager to become comfortable) in Python, JavaScript, or Bash to automate the boring stuff.
• The Human Element: You can translate complex technical jargon into actionable solutions for our customers.
• Academic Path: Currently pursuing a degree in Computer Science, Cybersecurity, or a related technical field.

Technical Toolkit (Preferred)

• Familiarity with Linux environments and the CLI.
• Foundational knowledge of DNS, SSL/TLS, and HTTP/3.
• Experience configuring web servers (Nginx, Apache) or playing with serverless technologies.

Bonus Points (The "Stand Out" Section)

• Cloudflare Power User: You have a personal site or project running on Cloudflare (Workers, Pages, or R2).
• Network Junkie: You've tinkered with BGP, GRE tunnels, or advanced routing.
