What we are looking for

We are searching for an enthusiastic, proactive and motivated Full Stack Developer with experience in PHP, LARAVEL 5,or otherweb frameworks, and DEVOPS practices to become the main in-house developer of the App OdourCollect (and progressively new Apps and IT Tools to come).

OdourCollect is a citizen science webapp. Citizens can report quickly and in real time ambient odours, which are recorded at the time and place where they are detected to be included on a global map.
