Your role
You will participate in the development and operations of complex server-side web applications. You will develop back-end components, connect the application with the other (internal and external third-party) web or mobile services, and support the front-end developers by integrating their work with the applications.
You will be responsible for managing back-end services and the interchange of data between the server and the users. Your primary focus will be the development of all server-side logic, definition and maintenance of the central database, and ensuring high performance and responsiveness to requests from the front-end. You will also be responsible for integrating the front-end elements built by your co-workers (and sometimes by you) into the application. Therefore, a good understanding of front-end technologies is necessary as well.
