Have you been TT faculty at a university in the past, or would this be your first position in academia?
This would be my first position within academia. I have a PhD in a STEM field. I would say I understand the research side of academia pretty well, as in many regards I am just like a research professor. I do recognize the administrative side and group dynamics would be very different.
I have posted elsewhere that I came into academia from an decade-plus career at a federal lab, and boy were my eyes opened. In most respects the prior experience was useful, but in other ways it severely screwed me up.
No matter what you do, be prepared to have your head turned around.
