Required:
- Familiarity with Web Frameworks such as Code Igniter/Kohana (PHP) / Django/Flask (Python) / Rails (Ruby).
- Experience with UI Frameworks such as Bootstrap/Foundation.
- Experience will be to their own benefit as they will have to hit the ground running. *CMSes (Joomla, Wordpress etc) do not count.
There might also be one role for an Android Developer (subject to how skilled they are).
While all this is important, if they do not have much experience but have enough drive that they are willing to spend some sleepless nights learning, then we can still consider them.
