I recently was given a job offer for a ( research support/IT support) staff position at a university in a city I have been trying to relocate to for family reasons but I am concerned that if I take the position any chance I have of getting a tenure track position will be over. My background is in computational physics and I have a successful post-doctoral appointment currently (multiple first author manuscripts in some high impact journals within the short time, 1 year, I have worked), but the location is not-ideal for personal reasons.
My question is: if I take this job will it look poorly on tenure track applications? If it helps the position is fixed-term and much better pay than my current post-doc. I have always been told in graduate school that if you get off the tenure path, you can't get back on.
EDIT: I should note that the IT position is listed as a Research position, where I will be providing research support for the supercomputing center by leading/developing workshops, presenting work at HPC conferences, and still writing manuscripts (just in more of a CS/IT domain instead of physics) and the position is only for about 4.5 Months. Didn't know if that would change anyone's responses, but thought I should clarify that it is not help-desk/sys. admin work.
