Dear @Arie,
Welcome back to the Wefugees Community and thank you for reaching out to us again!
I agree with @someoneingermany: as soon as your fiance is allowed to work (for the regulations for asylum seekers in a pending asylum procedure see also this thread), it rather depends on his qualifications, his language skills, his interests etc. than on the fact that he came to Germany as refugee.
All the best,
Meike
