Software Engineer, Workers Deploy & Config

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.

Position Location: Austin, TX | Lisbon, Portugal | London, UK

Role Summary

Join the Workers Deploy & Config team, the engine behind Cloudflare's unique serverless, edge-computing developer platform. This isn't just another backend role; you'll be building the critical, large-scale systems that empower developers worldwide to deploy everything - from a personal static site to full-stack applications serving millions of users. In fact, you'll be building the very foundation that the rest of our developer platform—from Pages to R2—is built upon.

You will tackle the complex challenges of distributed systems and high-traffic APIs every single day. Your mission? To build and scale the platform that lets customers upload, configure, and manage their Workers, ensuring it's incredibly fast, extremely resilient, and scales effortlessly. You’ll drive projects from the initial idea to global release, delivering solutions at every layer of the stack. You’ll get to master a diverse and modern tech stack, writing high-performance Go, architecting APIs, optimizing storage interactions, building Workers with JavaScript/TypeScript, and managing it all on Kubernetes.

We're looking for engineers who are obsessed with the developer experience and thrive on solving large-scale problems with a track record to prove it. If you care as much about the quality of the user's experience as you do about the quality of your code, and you want to join a high-impact, fast-growing team helping to build a better Internet, we want to talk to you.

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 1.1.1.1 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.
