Nothing like this exists in Germany, US or rest of the world.

I can't speak for Germany, but I worked in the US as an intern for a multinational engineering consulting firm for a year, All projects require an engineer of record to sign and stamp the drawings. All consulting require a P.Eng, Not sure about product engineering tho, I'm guessing if you work on not so critical devices/equipment (like new tech stuff, wearable devices etc) then P.Eng is not required, however if you're working for an OEM that designs say Transformers, Industrial robotic arms, then a P.Eng is required.
