Facebook owner Meta is set to cut almost 500 jobs in Ireland.
The firm said while it was not in a position to confirm the final number of redundancies now, it expects approximately 490 roles will be lost.
This will be across a number of teams including finance, sales, marketing, analytics, operations and engineering.
The final number will be subject to a collective consultation process, the company said.
The announcement and employee numbers relates to full-time Meta employees in Ireland, not contract workers.
"The redundancy timeline and process is defined by Irish law and government guidelines," the firm said in a statement.
"Meta will comply with their legal requirements in Ireland, as it has done previously".
Meta - which also owns Instagram and WhatsApp - said it had informed the "relevant policy stakeholders - including the relevant Government departments and state agencies."
It added that this announcement will have no impact on Meta's commitment to Ireland, which will continue to be the international headquarters and base for a "number of important company functions."
Meta employs over 3,000 staff in Ireland.
It is the latest tech company to announce lay-offs following Twitter, Amazon, Stripe and Google earlier this year.
