We are looking for an enthusiastic, self-motivated engineer to help us build the next generation of decentralized trading protocols. As a dedicated front-end hire, you will gain ownership of our existing suite of web products, as well as have the ability to influence the creation, design, and execution of future products. You will be responsible for ensuring a consistent, high-quality user experience across trading interfaces, data-heavy analytics pages, documentation portals and more.

What you will do

• Develop CowSwap and other user facing applications (e.g., the CoW Explorer) on top of CoW Protocol
