TU means Institute of Technology. Says nothing about being a good university. Your wife is likely bound to your location what limits her options and like has a degree that is not very in demand, at least not where she lives.

Engineering could be everything. And if she has a degree in, let's say food technology and is willing to work somewhere deep in east Germany for a very low amount of money then she would find a job.

"TU9 German Universities of Technology e. V. is the alliance of nine leading Technical Universities in Germany"

And I have a remote job and we almost have no location restrictions.

If there is no demand, how could she see the job advertisements and apply for them?

Well,ho many technical universities are the in Germany, not taking into account polytechnical universities?

What is her degree? And would you be willing to disclose her origin?

Not all advertised jobs exists. And in a blue chip company there are only three ways to get hired.

1. You have family contacts

2. Your professor has contacts

3. You work for a start up that gets bought by such a company
