Highly depends of your region. In France being an "engineer" means having an official Engineering Degree, or simply occupying an engineering position (the degree is not strictly necessary, you can have another one or even none at all).

The common ground of engineers throughout the world is more simply that they practice engineering... (and yes, this has a meaning -- managing requirements and developing in accordance to business values and economics comes to mind -- and yes, this can be applied to SE, and this is even quite "simple" to apply, at least this is not more difficult than for any other field)

I don't really see why some people pretend all the time that SE is different or young and it is not proper engineering. I never read a convincing argument about why it should be so. Of course they are differences but they also are differences between other fields.
