Additional Skills & Qualifications

Enterprise environment experience - this means that the candidate should have experience owning a product or a data center and truly understand how a configuration and/or change in the environment would affect everything else around it. Not looking for someone who can just do a task, but rather someone who will understand exactly what they are doing and what the goal of the change is.

Server experience and server management is good, but a second to the networking and firewalling. Any flavor is fine but most of the environment is Solaris and RHEL. Experience can vary, preferably someone who has intermediate to senior level Linux skills, but will train up on Linux as long as the candidate is eager to learn it.
