We have an established web app that's comprised of an Angular-based front-end (SPA), that interacts with a REST API built primarily on the Django framework running Tastypie, Celery, etc., with some functions driven by an app built in Groovy/Grails. We're looking for someone to help create interaction workflows and design interfaces for our front-end on an ongoing basis. You must be able to adhere to the general UI design and UX/IA principles that are already established, and create wireframes and designs for new features and updated functions within our app. Ideally, we'd like to establish a long-term working relationship with a talented designer that gets to know us and our product. We look forward to hearing from you!
