What you'll do
We're looking to expand the team building our AI Agent, Cloudy. We're looking for someone who is experienced (or at least interested in getting up to speed quickly) with technologies powering AI agents, and integrating them with Cloudflare's products and services. Cloudflare has a robust AI tooling offering like AI Gateway, Workers AI, workflows and others. You must also have a strong background in building the entirety of an application, from the user interface to the apis powering it.
We believe that great design is at the heart of any successful product. You will work closely with our design/UX team and must be comfortable seeking feedback from non-technical sources. We work iteratively and deploy often (can be several times a day). We build and maintain the Cloudflare Dashboard, a large TypeScript / React application, maintain a suite of common components published on npm, and build/package with Webpack. Other technologies we use include Redux, Fela, GraphQL, Apollo, Jest, Enzyme, Cypress, D3 and more.
Desirable skills, knowledge and experience
  • Minimum of 2 years experience building product
  • Strong fullstack engineering experience, with a bias towards Javascript/Typescript
  • Experience with building llm-powered applications and/or AI agents
  • Track record of building great interfaces and being detail oriented
  • Ability to work in cross-functional teams
  • Willingness to dive deep and understand product internals
  • Excellent debugging skills
  • Unit/integration testing experience

Bonus Points
  • Familiarity with the Cloudflare Developer Platform (extra bonus points for Agents Library)
  • Experience working alongside user researchers to build products
  • History of building products in complex systems
  • Knowledge of the broader Internet technologies (DNS, networking, etc)

What you need to know about the Belfast Tech Scene

If asked to name the birthplace of the RMS Titanic, you might not say Belfast. Similarly, if asked to name Europe's leading destination for foreign direct investment in new software development, Belfast might not come to mind. Yet, both are true. The city has emerged as a tech powerhouse, recently ranked among the best in the U.K. for tech careers — especially for software developers. It also leads the U.K. with the highest percentage of software development jobs advertised.
