Hello Chucks 1,
Nice to hear from you again and congratulations on your residence permit!
Usually your residence permit contains information about your work permit. Take a look at it and try to find out if it says "Erwerbstätigkeit gestattet". That means that you are allowed to accept all kinds of job offers.
If it says something different you can try to apply for a work permit at Ausländerbehörde. Or tell us what it says first and we can try to do some research to find out what's best for you to do.
