Contractors are common - from the company's perspective, you'd have an agreement with them to invoice them for the hours done per week/month. Your boss, or whoever, would sign off on the timesheet you'd submit, and the accounts dept would arrange payment.
I think it's more messy from your perspective. As a contractor you'd have to do your own tax returns (or hire an accountant to do it). It's not horrendously complicated, but it's not child's play either. There are questions around what country you'll actually pay tax in, if you're out of Ireland for more than x amount of time. There can be implications for your eventual state pension if you're not making PRSI contributions in Ireland (though that consideration might be there even if you don't do any work while abroad).
Add to that things like the need to bring any special equipment with you - fine if you're travelling in luxury, less convenient if you're riding a llama across the Andes for 6 weeks. This is where the messiness might/might not come in.
