Facebook is to hire an additional 1,000 people in Ireland over the course of 2019.
The extra roles will be created across 60 teams, including the social media giants' engineering, safety, legal, policy, marketing and sales teams.
The roles will based on 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 in Croke Park.
More than 500 small and medium businesses from Ireland and across the EMEA region attended the event.
Speaking on one of Facebook’s priorities in 2019 to earn users' trust, Ms Sandberg said: “Facebook is a very different company to what it was in 2016 or even a year ago”.
She detailed the steps the company has taken, and will be taking, in key priority areas including “the safety and security of Facebook’s users; the commitment to cracking down on fake accounts and false news; strengthening defences against election interference; and being even more transparent in how it operates and makes decisions, to make itself more publicly accountable”.
Meanwhile, Head of Facebook Ireland, Gareth Lambe, admitted today that 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 support all the government's initiatives, we think they're doing all the right things around planning, reform and cost benchmarking and all the infrastructure reform that we're doing.
"We think that will release this glut in a few years, we see it being not as bad in a few years," he said.
It was also announced today that Facebook would triple its investment in online safety programmes run by the National Anti-Bullying Centre (ABC) and SpunOut.ie, bringing the total investment to €1m.
The funding will go towards research and an online training program for teachers and parents of secondary school students.
An online safety resource for teenagers will also be created in partnership with SpunOut.ie.
