Your primary responsibilities will include maintaining and developing new features for a thoroughly unit-tested Rails application. Most work will be on the server-side, but knowledge of JavaScript and CSS is required. You will need to write readable, secure, and well-performing Ruby and JavaScript code. You should be able to understand business requirements and translate them creatively into software solutions, using best practices of object-oriented design. Familiarity with developing a JSON API is helpful. Experience developing native Android and iPhone apps is a plus.
