Ireland is a special case because its economy revolves around tax avoidance. As a multinational you credit your Irish division with all your European profits in your financials and claim the German operation is making a big loss - moving your tax burden to Ireland where it can be taxed cheaply or moved to tax havens.
This relies on doing certain finishing work in Ireland so that all the companies IP and operations can be credited there. You need your servers there, or shadow managers to sign off sales and investments made in Germany so that the sale can be credited to Ireland. So you need to hire in Dublin specifically.
e.g. but not the totality: https://en.wikipedia.org/wiki/Leprechaun_economics
"in 2019, the IMF estimated 60 per cent of Irish foreign direct investment was "phantom"
My main point here is that you can't use it as an example for this discussion as it is a special case.
