UI/UX Designer - Secure Messaging App

Remote friendly

Loki is an open source, decentralized, and secure communications platform. After nearly 2 years of product development, we are on the cusp of launching a brand new private messaging app that has no phone numbers, no centralized points of failure, and masks the user’s IP address. The project team is based in the heart of Melbourne’s CBD, and are seeking the talents of an excellent UI/UX designer to breathe new life into the UI/UX.

As we finalize our style guide, we are looking for a part-time or full time designer to join the 6 person development team over the next 6 months to create a new look and feel for the app on all three platforms, including Android, iOS, and Desktop.
