Up to 131 roles could be lost at Paypal's operations in Dublin and Dundalk, staff have been told.
The online payments firm is proposing to relocate a selection of positions in a limited number of teams in both locations to other locations around the world.
Impacted workers will be able to apply for other jobs within the company, or for an enhanced voluntary redundancy package.
"PayPal is committed to?ensuring that colleagues who leave under the proposed changes are treated fairly and generously," the firm said in a statement.
Staff were briefed on the situation this morning.
The proposals are subject to consultation with the workforce over the coming weeks and arise from a review of the company’s operational needs.
Paypal currently employs more than 2,800 people in Ireland.
The company said it remains completely committed to Ireland and that there is no threat to its sites in Dublin or Dundalk.
"PayPal’s sites at Dublin and Dundalk will remain two of PayPal’s largest global centres for employment as critical hubs for the company’s global operations," it said.
"The company will continue to recruit the best possible talent in Dublin and Dundalk to meet the needs of its business."
In 2012, the company announced 1,000 jobs at a new International Operations Centre in Dundalk, with a further 400 following in 2014.
In 2016, it said that it planned to expand its presence in the Co Louth town following its separation from eBay, after a decision by the online auction site to close its Dundalk office with the loss of 150 jobs provided an opportunity for Paypal to expand there in what was a shared facility.
The same year it also announced 100 new jobs at its Dublin office, where it has been operating since 2003.
In 2009, PayPal invested €15 million in the establishment of a European Centre of Excellence in Blanchardstown.
