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.

We realize people do not fit into neat boxes. We are looking for curious and empathetic individuals who are committed to developing themselves and learning new skills, and we are ready to help you do that. We cannot complete our mission without building a diverse and inclusive team. We hire the best people based on an evaluation of their potential and support them throughout their time at Cloudflare.

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 hugely 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
We're building the foundational tooling and platform capabilities that power the next generation of AI agents on the Cloudflare Developer Platform. Our goal is to make it easier for AI agents to communicate, interact with the web, and work together - all while maintaining performance, scalability, and security.

Our team is leading efforts to ship core platform primitives for AI agent orchestration, including the Cloudflare Browser Rendering API, which enables efficient, headless browsing for agents. We're also focused on AI auditability and traceability for site owners, along with creating frameworks for seamless Agent-to-Agent interactions. Working closely with other Cloudflare platform teams, we're shaping the future of how software engineers build, deploy, and manage intelligent agents at scale.

We are a tight-knit team that communicates and collaborates regularly. We celebrate our achievements, support one another through challenges, and hold both our work and each other to the highest standard.

What You'll Do
In this role, you will join world-class engineers in shaping new products built entirely on Cloudflare's global network, while continuing to nurture the growing impact of existing offerings—ensuring continual reliability, best-in-class performance, and the implementation of new features and functionality.

You will be encouraged to bring your ideas forward and own your code from inception to release, delivering solutions at every layer of the software stack to empower Cloudflare customers. On any given day, you might:

• Write a design document outlining your strategy to tackle a specific challenge.
• Ship a new feature that integrates multiple technologies.
• Architect and deliver innovative API primitives for our AI agent platforms, including enhancements to the Cloudflare Browser Rendering API.
• Fix a bug affecting how our user experience renders.

You can expect to work with a variety of languages and technologies including, but not limited to, TypeScript, Go, and Rust. We use Cloudflare Workers heavily and creatively. If applicable to ongoing projects, you will also help maintain the health and availability of services by participating in an on-call rotation.

About You

• You have a passion for meeting business needs while building technically innovative solutions, and you excel at balancing big-picture goals with technical detail.
• You are bold and persistent in your efforts to get your work across the finish line.
• You are excited to collaborate and communicate with engineers across Cloudflare, contributing to many layers of the stack.
• You take pride in shipping effective, reliable code.

• You are keen to explore emerging AI technologies and are excited by the opportunity to integrate AI agent platform primitives into our product suite.

• Experience building reliable, high-performance distributed systems or working on cloud platforms.
• Familiarity with the Cloudflare Workers development platform.

What Makes Cloudflare Special?
We're not just a highly ambitious, large-scale technology company. We're a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.

Project Galileo
: Since 2014, we've equipped more than 2,400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare's enterprise customers--at no cost.

Athenian Project
: In 2017, we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration. Since the project, we've provided services to more than 425 local government election websites in 33 states.

1.1.1.1
: We released to help fix the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released. Here's the deal - we don't store client IP addresses never, ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.
