In which countries are Software Engineers not allowed to call themselves engineers unless they are professionally qualified engineers?
In many, I am at least aware of Portugal, Germany and Canada. https://www.lexpoint.pt/Default.aspx?PageId=128&ContentId=60... https://www.vdi.de/news/detail/wer-darf-sich-ingenieur-oder-... https://engineerscanada.ca/become-an-engineer/use-of-profess... You can call yourself engineer if you feel like it, however in case it comes to some court case due to liabilities and such, there might be some issues coming up with…
In Germany I don't think that counts. "Software Engineering" as a title isn't regulated (as kcexn is asking for). The German term "Softwareentwickler" more literally translates to "Software Developer" (as opposed to "Ingenieur") but I don't see companies having problems translating that in job posts and even contracts to "Software Engineer". I've never seen "Softwareingenieur" used tbf.
Getting into Germany as a Software Engineer (for app development) is also as relatively frictionless as it gets in comparison to more-traditional engineering fields.
Verdi is the German trade union so they have to make these kinds of distinctions about which professions they can represent. Don't quote me on this one but I think Verdi represents very little of the modern "app development" software engineers. I guess those who work for more traditional German industries like auto-manufacturing can fall under their umbrella.

[LESS INACCURATE EDIT AND MY THOUGHTS IN LESS WORDS:]
In Germany "Ingenieur" (Engineer) is a loaded term with legal implications so "Software Engineer" is "Softwareentiwickler" (Software Developer) instead. But really this is an HR sleight-of-hand trick. At the end of the day, getting into professional Softwareentwicklung is the same in Germany as in elsewhere that calls it "Software Engineering" (and IMO is what kcexn was asking about anyway).
