Frontend Developer (m/f) all levels // CHECK24 Profis

August 1, 2018

We are CHECK24 Profis, a company of the CHECK24 Group, Germany’s biggest comparison site with more than 15m customers.
Our vision is to revolutionize the way people accomplish their personal projects through matching customers to the right service expert. CHECK24 Profis lets you find and book local service providers, for almost anything. It’s simple and convenient. Whether they are searching for a personal trainer or a DJ, our customers simply describe their project on and get introduced to the right service provider. Both sides of the marketplace benefit from a strong mobile experience. So they can hire professionals with a few finger taps or manage their business on the go.

Our frontend is mostly composed of Ruby on Rails applications on top of our backend which is written in Ruby. For those applications we utilize Javascript as a supporting language to bring dynamic behaviour to the page. We have several JS applications which are Single Page Applications (SPA). For those applications we work in the React (Redux, redux-thunk, react-router, Jest, ES2015, Babel, webpack) ecosystem. In our applications we use component based ideology for decoupling and reutilization.
