We need a developer who is able to work with a high degree of autonomy (i.e. able to work and be innovative given general goals, with minimal supervision needed). Documentation skills are required – all work has to be properly documented for the rest of the team.

The ability to design usable, attractive user interfaces is needed (most of the work is on our client-facing interfaces).

We need knowledge of browser and app interaction (specifically single-signon, javascript-java bridging, intents and mime-types, cookie injection and other techniques)

The developer has to be familiar with change management software such as SVN and Git and Jira for issue tracking and reporting.

Also, we need someone who is able to create and execute unit testing and initial QA on apps, including creation of test plans and setting up test environments for our QA engineers.

• Experience with real-time notification systems (node.js, React, etc)
