I am aware that in Germany if you get an equivalent of a British master's degree in engineering you get the title Dipl.-Ing..
I am also aware that in Germany that tends to precede the name, in much the same way as somebody in the UK with a PhD gets to call themselves Dr. Jones instead of plain old Mr. Is it acceptable to change this order from
Dipl.-Ing. Johann Schmitt
Johann Schmitt Dipl.-Ing.
Edited to answer questions:
We use a third party database for HR purposes. It is old and inflexible and does not currently support qualifications that go before the name. The Title field (Prof, Dr., Mr, etc.) is not free text and will not currently accept the German title. We are trying to decide whether it is acceptable for the German title to go at the end or whether it'd be enough of an excuse to reach into our pockets for a new HR database.
