The prestige of your DII conference plays absolutely no role whatsoever in determining what sort of DII job you can get. Also, in DII and DIII, conference prestige has absolutely no impact on team prestige.
Barring a deep NT run, it is very unlikely that you will be qualified for any DI jobs after this season. If you can go to back-to-back NT's that will probably open you up to some low level (D/D-) jobs after next season.
Also, it's not your team's prestige that determines what jobs you're qualified for, it's your resume. Now, prestige is certainly impacted by what's on your resume. But I'll give you an example of why it's resume and not prestige that matters:
We have equal DIII careers, and then I take over an A+ prestige DII program, you take over a D-. I make the NT 2 of the next four seasons, one PIT and one .500 season. You make 3 NT's and a .500 season. Our NT success is the same.
My prestige would be higher than yours by virtue of the fact that I inherited a program with much higher prestige. But you would have the better resume and the edge over me if we both applied for the same job.
Hope that clears things up for you.
