Project description

As a JavaScript framework developer you will work on “The backend of the frontend,” enabling our customer’s client applications to communicate in realtime via the PubNub network. Your focus will be on network communication, client state management and use case specific data structures and logic. You will develop frameworks for a JavaScript and TypeScript developer audience to bridge the gap from the network to popular frameworks like React, Redux, MobX, Vue and Angular.

PubNub is a globally distributed messaging infrastructure as a service. The PubNub platform powers realtime applications across a wide variety of use cases including chat, multiplayer games, ride dispatch services, social events, online auctions, education apps, notifications, IoT and more.

You will start with the use case of chat.
