Jobs for expats in Mwanza

Hi, I am thinking about moving to Mwanza but I am not sure if I will be able to get a job there. I am an American and will be moving there to live with someone who is a native to Tanzania which will make the transfer a little easier.

But not sure if there are any jobs for an expat there. Any suggestions? My background is in hospitality and marketing but I do not speak any other language besides English.

Thanks for any advice or suggestions.
