Briefly, the question is: what are sensible career choices for a trained mathematician (with a doctoral degree) outside of academia?
The situation I've found myself in is the following. I have been employed as a teaching assistant at one of the top Polish universities for a year now. The salary of TAs in Poland is borderline acceptable (as in, if it were a little bit less, one wouldn't be able to make ends meet), but when I was signing a contract, I was promised I will be promoted to assistant professor after a year.
Now, I was informed a few days ago that I am not getting said promotion, but they'll be happy to keep me as a TA. It was stated very clearly that this is happening not because I am not doing my job properly (in fact, I have a pretty solid track record); apparently the university is in financial troubles. As a corollary, I may be stuck as a TA for quite some time.
I have a family to provide for, so this is unacceptable for me.
To make matters even worse, the timing of the information left me without any option to pursue a postdoc position. This got me thinking that -- even though I enjoy doing research and teaching very much -- perhaps it's time to take that step and decide on changing career path. The problem is, I don't really have any experience in work outside of academia. I feel that I am professional and disciplined enough to handle any kind of work, but sending resumes at random doesn't seem like a good idea.
I realize the question may be too vague, but I'm thinking maybe someone has already been down that road and has some advices to share.
