Facebook is to hire an additional 1,000 people in Ireland over the course of 2019.
The extra roles will be created across the social media giants' engineering, safety, legal, policy, marketing and sales teams and based in its Ballsbridge campus which was previously home to AIB.
The expansion will bring the total number of people employed across its centres in Cork, Dublin and Meath to 5,000.
The announcement was made in Dublin today by the company’s chief operating officer, Sheryl Sandberg, while she attended Facebook's Gather event.
Head of Facebook Ireland, Gareth Lambe, admits the company is concerned about the current housing crisis gripping the country.
However, he says it is not something which has stunted Facebook's growth, and insists he has faith in how the government is tackling the problem.
"We're concerned, of course; to date, it hasn't been a blocker for us hiring, we have over 4,000 people here in Ireland and announcing another 1,000 today is a big investment," he said.
"We think that will release this glut in a few years, we see it being not as bad in a few years," he said.
