Technical Support Engineer Intern (July to December 2026)

Cloudflare • San Francisco, CA

3d • Onsite

About The Position

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. 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.

• You can translate complex technical jargon into actionable solutions for our customers.
