Facebook is to create 200 jobs at its international headquarters in Dublin.
The company said the full-time roles in sales, engineering and online operations will be filled by the end of the year.
“The announcement is a key milestone in Facebook’s commitment to investing and growing its presence in Ireland,” a Facebook spokesman said.
The social network giant recently doubled the size of its premises in Dublin’s Silicon Docks, where it already employs 1,300 staff.
As part of the expansion, it has opened a Facebook Partner Centre, the first of its kind outside the company’s global headquarters in Menlo Park, California.
The centre focuses on Facebook’s apps and services as well as its longer term investments in connectivity, artificial intelligence and virtual reality.
Earlier this year, the company announced it was starting to build a new data centre in Clonee, Co Meath – its second in Europe and first in Ireland.
Ireland’s jobs minister Richard Bruton said the investments would bring huge advantages for the country.
“Not only does 200 direct jobs within Facebook mean hundreds of extra jobs in the local economy through supply and services companies, but these investments have huge knock-on impacts for the start-up community and for our ability to attract more multinational investment,” he said.
Facebook opened its first office in Ireland in 2009.
