As a Frontend Software Engineer at Cloudflare, you'll develop innovative email services, manage code through all software layers, and enhance developer experience, primarily using JavaScript, TypeScript, and React.
Available Locations: Lisbon, Portugal 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.
What you'll do
As a Frontend Software Engineer focused on Cloudflare's Email Service, you will shape the future of industry-leading services that redefine what is possible for developers. We don't just copy what other cloud providers do; we work backward from developer needs, reimagining solutions by leveraging our unique global network.
You will own your code from inception to release, delivering solutions at all layers of the software stack to empower Cloudflare customers. On any given day, you might be architecting a new dashboard for metrics, optimizing page performance, or designing a novel API for a new product feature. You can expect to interact with a variety of languages and technologies including, but not limited to JavaScript, Typescript, and Go
