Full Stack Developer for Bioinformatics Project

We are developing a bioinformatics platform. Aside from the web application written in php, the core technology stack is
* php
* nodejs
* javascript
* jquery
and we are looking for one or two good full stack developers to help our existing teams.
* Experiience with big data (hadoop)
* Experience with data upload operations (we need surgeon precision on this topic as we are working with large datasets)
is definetely a plus.
This is a long term position after a decent amount of trial period.
