Is "german" very important to get data science related job in Germany ?

I am planning to move to germany via masters route.

I understand the importance of german language & would be learning it well. I want to do part-time or intern related job during masters. Since I have experience in data/product analytics, I would like to get part time job into the same. Will lack of german knowledge would be a big hinderance in this field ? Thanks.
