If your university offers computer science as a bachelor of engineering, it actually does grant you the title.
That's not correct. E.g., consider the relevant section in the Bavarian engineering law[1] (using Google Translate):
> The job title engineer alone or in a word combination may use,
> (1) Anyone who has successfully completed an undergraduate degree at a state or state-recognized German university
> a) in a technical-scientific subject,
> b) which has a standard period of study of at least six full-time semesters and with which at least 180 points can be acquired using the ECTS system and
> c) in which the areas of mathematics, computer science, natural sciences and technology predominate; this requirement does not apply to people who have completed an undergraduate degree in industrial engineering and only use the professional title in the word combination industrial engineer
Further, my diploma for a Bachelor's in Computer Science from TUM contains the passage:
> The graduate is entitled to employ the designation Engineer alone or as part of a compound word.

I believe around 2005 most german universities switched to granting masters and bachelors, usually „of Science“ for technical subjects. The title is in english, also in german language context.
And Berlin is (I'm told by everyone here) much more English language than anywhere else in Germany.
For conservative big names engineering like Bosch, Simenns or traditional mittlestand companies that mostly operate with German customers, yes they still use it. Xing is full of German only job ads.
But for software only companies operating international looking to attract foreign talent off LinkeIn, no, it's all English.
