To me, systems engineer sounds better than IT Manager. It sounds more focussed, as opposed to a "Catch-all" title that could include everything. I've known people who purely replace toners in printers and handle the photocopying, they were still listed as an IT Manager.
You know what thats too funny, as in my old job after 8 years my manager came up with an ingenious plan to get me to to monitor nagios alerts to change ink cartridges.
I eventually refused to do it as I told him this was not appropriate use of my time.
Suffice to say that was the beginning of the end and hence why I've moved on.
In this role, every day I'm learning. In that role, my job was just utter crap. I was just used to do the crap no one wanted to do.
