“with (or) in the profession of”

I have two questions.

1. Should I use 'with the profession' or 'in the profession' in this text?
2. Is this sentence gramatically correct?

Completed his education at the company-affiliated Basic Vocational School for working people WZE in Berlin with the profession of turner.

WZE - name of school

Your first question is mystifying, so I will address your second one and see if you edit to clarify.

The second sentence could do with some punctuation for clarity. A better phrase than 'with the profession' would be 'qualifying as'. So:

Completed his education at the company-affiliated Basic Vocational School for working people, WZE, in Berlin, qualifying as a professional turner.
