About the Department
Cloudflare's Engineering Team builds and runs the software that handles large amounts of requests on the Internet today. We also build and run the internal tools and platforms that run that software. Individual engineering teams are typically responsible for large areas with considerable impact, and able to execute autonomously within that space to deliver value to their customers - be they internal or external.
About the Role
We are seeking a skilled Frontend (UI) Platform Engineer to join our team. You'll be responsible for the core technology that drives the Cloudflare Dashboard. You'll be pioneering new techniques and tooling to move away from a traditional monolithic application and onto Cloudflare's innovative Web Fragments. In this role, you will enhance UI infrastructure, streamline development workflows, and collaborate across teams to improve code quality and developer velocity. Your contributions will be pivotal in refining the developer experience, ensuring high-quality frontend delivery, and optimizing performance and reliability at scale. Our mission is to improve developer productivity and application performance.
Key Responsibilities
  • Help build, migrate, and scale the UI platform frameworks.
  • Drive UI infrastructure excellence, including CI/CD, observability, and experimentation tools.
  • Tackle cross-cutting concerns to enhance developer velocity, maintainability, and code quality.
  • Upgrade and maintain the frontend codebase, modernizing legacy components to align with current best practices.
  • Collaborate with product and design teams to deliver cohesive, self-serviceable user experiences.

Technologies We Use
React, TypeScript, JavaScript (ES6+), Remix, Qwik, PlayWright, Cypress, Vite, Webpack, Bazel, CI/CD tools, Go, RESTful APIs
Qualifications
  • We want someone who understands and obsesses over front-end systems.
  • Passion for improving developer experience and increasing development velocity.
  • 4+ years of experience in frontend engineering, specializing in JavaScript, TypeScript, and React.
  • Strong knowledge of UI infrastructure, CI/CD, and testing frameworks (e.g., Playwright, Cypress).
  • Proven ability to drive projects independently, from concept to implementation.

Preferred Skills:
  • Expertise in React.js, TypeScript, and modern front-end systems.
  • Expertise in performance optimization for frontend applications.
  • Experience with modern JavaScript bundling tools like Webpack, Vite, and Bazel.
  • Familiarity with Remix, Qwik, RESTful APIs, and Go.
  • Experience building and maintaining integration test suites with API mocks.
  • Experience building and scaling large-scale web applications.

Why Join Us?
  • Lead a pivotal migration to a modern, scalable UI platform.
  • Shape best practices and drive impactful engineering change.
  • Work with modern technologies and solve large-scale challenges.
