Hundreds more Facebook jobs are set to come on stream in Ireland next year.
The news comes after the Taoiseach Leo Varadkar visited the social media's headquarters in Silicon Valley today.
He also met with Facebook's founder Mark Zuckerberg, as part of his trade mission to the US west coast.
Varadkar is also due to meet with Apple CEO Tim Cook later.
Facebook employs some 2,200 people in Ireland, it has grown from 30 people in 2009 to currently employing more than 2,200 in Dublin and Cork.
It is expected the positions will be based at its International HQ in the capital.
Gareth Lambe is Head of Facebook Ireland.
He said: "We employ over 2,000 people here now and we have quite a large footprint.
"We have our International Headquarters in Grand Canal, we've taken another building in East Wall, we are just completing our data centre in County Meath and expanding that, we also last year, made an aquisition of a virtual reality research company in Cork.
"So it is by far the largest footprint Facebook has in any country outside the US."
