You will be very welcome as an engineer. We do have english speaking countries in the EU: Ireland and Malta have it as their official language but others like The Netherlands will give you not much problem and then there's plenty of cities to look at like Berlin, Vienna, ... Even in the rather small Austrian city of 200k pop where I live I know a South African woman who gets along just fine as English teacher. European cities are becoming the melting pots again they had been before the world wars. Just learn the local language and don't fall into English too often, the natives will do switch to English but I finally got into the habit of having bi-lingual conversations which is great fun.
