Cloudflare's pledge to hire as many as 1,111 interns in 2026 — a figure borrowed from its 1.1.1.1 public DNS resolver — ran against the grain at a moment when many companies were pulling back on intern and new-graduate hiring. The company's reasoning: AI lets early-career engineers learn a system faster and take on harder problems, but it doesn't replace the curiosity and fresh perspective a new hire supplies.
One year in, that work is reaching internal teams and millions of customers. The blog itself runs on EmDash, whose second maintainer joined as a summer intern.
Where the program stands
Cloudflare has hosted 750 internships across 48 teams in nine offices — Austin, San Francisco, London, Lisbon, New York, Singapore, Bengaluru, Washington DC, and Sydney — and is still hiring toward the 1,111 target.
Interns joined active teams from day one and were expected to leave something behind: a shipped product improvement, a new piece of infrastructure, a better process, or an insight that changed how a team works. The impact was not confined to engineering. An internal audit intern built an AI-assisted pipeline to automate ISO compliance control testing and documentation; a product manager intern worked on an API, dashboard, and migration tooling to modernize credit management for the Startup Program; a people team software engineering intern improved background-verification workflows; and a customer support intern explored triggering troubleshooting commands from case descriptions using AI.
AI as acceleration, not a shortcut
AI ran through the whole program without lowering the bar on learning or accountability. Interns used it to read unfamiliar codebases, compare product requirements against implementation, prototype, automate repetitive work, and shorten the distance from question to working solution. Managers and mentors stayed responsible for direction, reviewing decisions, and holding shipped work to Cloudflare's standards.
For many interns, AI moved the starting line: mapping a project in days instead of weeks and producing a working scaffold quickly, leaving more time for the hard questions — what to build, who will use it, how to know it is correct, and what happens in production. One intern framed it plainly: “How did previous interns ship anything in 12 weeks without AI?”
What the interns shipped
Cache Transcoding. With RAM and disk prices climbing sharply, intern Aashi asked whether Cloudflare could get more cache capacity from existing servers. The resulting Cache Transcoding compresses eligible assets with Zstandard inside the primary proxy before they are written to disk. Initial testing shrank them to a third of their original on-disk size on average, pointing toward petabytes of effective cache capacity and less data moving between data centers.
EmDash. Noah joined as an intern and became the CMS's second maintainer, contributing across the media library, content editor, and admin interface. EmDash 1.0 shipped during Birthday Week.
Post-quantum readiness. With Cloudflare targeting 2029 for post-quantum security, Tiago helped build CryptoLabe, an internal AI tool that finds cryptography across the codebase and maps its dependencies. Sophie helped bring per-connection post-quantum visibility to Logpush, Log Explorer, and HTTP Traffic Analytics so customers can track their own migration.
BGP. Iliana measured how often networks rewrite BGP's ORIGIN attribute to steer traffic toward themselves, finding it on roughly 70% of observed paths, then publicly advocated removing ORIGIN from route selection. She also tracked adoption of RFC 9234, which lets routers reject route leaks on their own.
Several Birthday Week launches included intern-authored or intern-engineered work:
- Protected Quick Tunnels: simple accountless authentication for your next dev project
- Using AI to chart a course for our post-quantum migration
- Is your domain using post-quantum encryption? Now you can see for yourself
- EmDash 1.0: the stable CMS with a secure plugin registry
- Supporting native Rust in Workers with the new Emscripten target for wasm-bindgen
- How fast is the web? Explore billions of real-user measurements with BEACON
- Cloudflare Containers, rebuilt to scale agent sandboxes

Community and what follows
Beyond the work, interns shared meals and volunteering across offices. CEO Matthew Prince hosted dinners with interns worldwide to hear what they were building, and executives joined Q&A sessions on strategy, technology, and careers alongside day-to-day mentoring.
Cloudflare plans to grow the program next year with a new cohort, more participating teams, and more learning about how early-career people do their best work with AI and with the people around them. Many of this year's interns are returning full-time — the stated outcome being a career, not just a good summer. Students and early-career technologists can apply to the internship program, with roles opening throughout the year.
