We need to transition from a single mongo db instance, to a sharded environment with several "slaves". We will need performance monitoring tools installed and monitored, and/or explanations to developer staff (and yourself) on how to use them and come up with solid performance metrics so we know whats working and whats not, as well as identify queries which are under-performing. The administrator should be familiar with centos and ubuntuLTE administration, and be comfortable with several stacks. This includes the installation and tweaking (to get the most performance out of) python, java, mongo, redis, php, apache, etc, and identify sore points.
Skills: administration, apache
