System Administrator

A Sys Admin’s work is never done.  Keeping your infrastructure humming along like a well tuned starship requires equal parts Geordi LaForge, Kaylee Frye, and Chewbacca.  From well meaning but misinformed users requesting root access to hardening gateways against DDOS attacks, it’s a job that if done right, looks like you’re doing nothing at all.  Far from it, a sharp sys admin, keeps abreast of the stream of constant changes to the technology stack.  Everything from disk arrays, to network switches, OS kernel updates and beyond.  It’s a tough job, but building and maintaining a fast and reliable infrastructure can make or break a company.  That’s where you come in.
