Job Description

About Us

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.

About the Department

Emerging Technologies & Incubation (ETI) is where new and bold products are built and released within Cloudflare. Rather than being constrained by the structures which make Cloudflare a massively successful business, we are able to leverage them to deliver entirely new tools and products to our customers. Cloudflare’s edge and network make it possible to solve problems at massive scale and efficiency which would be impossible for almost any other organization.

About the Team

Workers AI is Cloudflare’s AI inference service, enabling customers to use a wide variety of AI models both within Cloudflare’s Workers development platform and via API. The Workers AI team owns the whole stack that powers the product, from front-end development all the way to low-level inference code. Accordingly we’re a team with a diverse array of technical skills, but everyone on the team is curious and passionate about the possibilities of generative AI.

What You’ll Do

The Workers AI AI/ML team is responsible for deploying AI inference on the GPUs within Cloudflare’s network, as well as building innovative features that enable developers to incorporate AI into their own products. You will be a technical leader on the team responsible for maintaining the Workers AI model catalog as well as the Workers AI AI and ML inference code. You will be building products and APIs that will be used by others, and will add your strong sense of what makes a good developer experience to the team.

Examples of desirable skills, knowledge, and experience

Experience setting the architecture and technical direction of large, cross-team and cross-functional engineering projects
Strong communication skills
Comfortable with tight deadlines and short release cycles
Expert-level knowledge in Python for AI development, particularly pytorch or tensorflow.
