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)
I live in Tucson and am quite familiar with Raytheon (having been recruited and know numerous employees as they are the biggest employer here). They are not going to be hiring remote developers from Ireland. In all likelihood, they will not be hiring any remote developers anywhere, unless those people will be relocating to Tucson and being on premise once this calms down.
My completely naive/distant presumption of sites like these is that they are fundamentally incompatible with the security concessions inherent to remote work.
