Well done on putting together that amount of money. If you were having some difficulties with getting mortgage approval I would suggest using a Mortgage Broker. A quick google would show you a number of different options.
I suggest that because you have excellent saving habits and you would be very capable of managing it. You could use 200k of your savings towards the house purchase (as an example) and split the rest between an emergency fund, maxing out your pension, furnishing the new home etc.
You are no doubt very aware of age related pension investment relief in Ireland. So at 40 years of age (did you turn 40 last year ?) you could put 25% of your 80k salary into a pension wrapper. You would need to expand on when you will return to Ireland and when you left as you could only put in 25% of the money you earned in Ireland last year.
In terms of rethinking property purchase I agree with Khublei in their post @ 7 above. Property investment (outside of your main home) comes with many risks in Ireland. However you need a place to live and if Ireland is your long term choice then definitely purchase one.
People are asking for more information around your work because they can the then factor in your pension entitlements etc. into the mix and give you better advice.
Edited to add (E.T.A.)
It would seem that you had a typo in the amount of money you had saved up ? It has now changed from €330,000 to €30,000 ?
