Javascript Engineer

We are looking for a JavaScript Engineer whose passionate about creating polished web applications with beautiful, well-designed UIs using modern JavaScript libraries/frameworks. 

On a day-to-day basis, you'll be collaborating with multidisciplinary teams building out interfaces for web sites as well as web applications. 

Your primary responsibility will be the implementation of visual elements and their behavior with user interactions, and adhering to the style and guidance of the design and technical teams. You will also be bridging the gap between the visual elements and the server-side infrastructure, taking an active role on both sides, and defining how the application looks and functions.

Because the range of projects is diverse, we need a web developer with experience working on a wide variety of projects – building custom UI components, implementing responsive interfaces, or working to improve the responsiveness and performance of our application. You’ll work directly with designers to create new customer-facing features, from idea, through prototype, to release and maintenance.
