Up to 280 job losses have been announced by Hewlett Packard (HP) after the firm lost a major contract.
The company said employees based at a call centre in Sandyford in Dublin have been notified of the decision to axe 220 staff and 60 contractors.
The HP multilingual call centre, which operates pan-European services on behalf of Barclaycard, will close by March of next year.
It said the client made the decision to move the service closer to customers in Portugal and Italy.
"HP is fully committed to its operations in Ireland and will work closely with its employees on the transition and redeployment opportunities to help minimize any impact and ensure high standards of customer delivery quality are maintained," it said in a statement.
"HP continues to hire in Ireland in line with recent announcements and is on schedule to build a new state of the art facility at its site in Ballybrit, Galway."
The company employs about 4,000 people in Ireland.
