> When you get a degree you get a transcript where all local grades are translated to to ECTS, which you then would use to apply for jobs

https://www.google.com/search?q=%22job+application%22+%22ECT... gets me only a handful of results and a warning that 'It looks like there aren't many great matches for your search'

Do (m)any European employers know about this scheme?

Job applications in Europe typically list a degree that is required, rarely the score that an applicant is expected to have received. Nonetheless, ECTS scoring is nowadays awarded to every degree that is obtained in a country that is a signatory to the Bologna accord. To answer your question, it is an established standard.

It seems that ECTS is indeed useful to those who move internationally between institutions during a course of study (Erasmus and similar).

I'm struggling to detect much of a use case once a qualification is achieved and someone's looking for work.

OK, but so is Esperanto :)

The diploma comes with an explanatory supplement (at least mine does), so employers don't really need to know about it, they just need to read (and maybe they won't do that).
