REIT - back office?

I was wondering if anyone could help me out in determining if this position with a mortgage reit is a traditional "back office" position. the role, from what I can tell from the description, will center around analyzing and evaluating organizations who sell the underwritten and originated mortgages to the reit. the analysis will be quantitative and qualitative, but I believe the companies will be organizations like banks or mortgage specific companies. obviously sort of a niche industry and market, and i dont believe i will have much exposure to the investor-facing side of it or the MBS trading desk at the firm. does anyone have any idea about the potential for this role? would it be good background for a potential move to a FIG group or something like that, or a trading desk or commercial real estate position? any other insights would be appreciated, and i can try to clarify things more if im not being clear in the description.

Thanks in advance
