Here's the top hits in order for me:
Sherrif's office- http://www.teamdane.com/Securi...
Simply hired- clicking through shows that nothing on the first page of results actually calls the job that- the first results are signal support systems specialist, Sr client support specialist, field technician support specialist, Mac Support Specialist, and a SOX compliance officer.
Another link to Dane County
Another job site, a similar mix of results none of which actually use that title, although these tend to match the word security rather than support specialist
And finally a Cisco cert, for those who still give a shit about such things.
And a glass door salary link which shows two people nationwide using that title both at USAA.
Yeah, made up title.
