I am currently a researcher ("postdoc") at a world-class university. I have an assistant professor job offer from a business school in the New York area where I would be doing research in quantitative finance (financial mathematics/statistics). I am 35-36 years old.
In all honesty I am getting tired of academic work, and don't see myself doing it for much longer. I am rather certain this will not change when I have to juggle research/teaching/grant applications/departmental service, and at the same time feel underpaid.
However, since I'm already there, I would like to give the professorship a shot for a year or two, work on research projects that interest me, without pressure so to speak since getting tenure is simply not a do or die thing for me. I am also about to become a father and being a professor would be convenient for the first couple of years.
My question is: Is it going to be extremely hard for me to find a position in finance (or related field like insurance) after being an assistant professor, and being in my late thirties? I worked for one year in the financial industry after my PhD, I have a good quantitative skill set, and my research is also related to finance/technology (in short: my degree/research is not "useless").
I know there is demand for me at this point as a postdoc at my current institution, but I am unsure how I would be perceived as a professor from a second-tier business school.
