I work for a government contractor on a tier of clearance far below what's used in defense, and we are not even allowed to take any US Gov't issued equipment outside of the US, much less actually work from there.

No way in hell anyone in Ireland is going to be doing US Gov't contracting work, unless they are on the US Embassy grounds.

Sorry. (Government contracting is exactly what the original recommendation describes..unglamorous but steady, FWIW)
