Facebook has announced it is to add 1,000 new roles in Ireland this year.

The roles will be across 60 teams, including engineering, safety, legal, policy, marketing and sales.

The expansion will bring to 5,000 the number of people employed by the company in Ireland at its sites in Dublin, Meath and Cork.

It follows the company's announcement in November that it has taken a long-term lease out on the Bank Centre campus in Ballsbridge, currently home to AIB.

The announcement was made by Sheryl Sandberg, the company's chief operating officer, who is in Dublin to attend Gather, a Facebook-run event for 500 small and medium-sized businesses from Ireland and Europe.

Facebook also said today that it was increasing the amount of money it was giving to online safety programmes being run by the DCU Anti-Bullying Centre (ABC) and SpunOut.ie, with the total amount due to reach €1m.

DCU President Prof Brian MacCraith welcomed the increased investment which he said will go towards supporting important research conducted by ABC, expanding the nationwide online safety training program for teachers and parents of secondary school students, and creating online safety resources for teens in partnership with SpunOut.ie.

In a keynote speech to attendees at the event in Croke Park, Ms Sandberg acknowledged that the social network needs to earn users' trust. 

She said Facebook was now a very different company to the one it was three years ago, or even one year ago. 

Ms Sandberg also outlined measures being taken to address challenges such as cracking down on fake accounts and fake news, preventing election interference, increasing safety and security for users on the platform and becoming more transparent in its decision making.

The Bank Centre campus development will give Facebook capacity for up to 7,000 employees.

All 2,000 employees currently based in the company's Grand Canal Square office will have moved to the new campus by 2022.

Ms Sandberg also met Minister of State for European Affairs Helen McEntee at the event and later held discussions with Data Protection Commissioner Helen Dixon.

She also visited DCU where she met with a small group of teachers to discuss the issue of bullying in schools and to hear first-hand experiences from those dealing with bullying both on and offline.

Ms Sandberg then addressed over 100 teachers attending the first anti-bullying training session as part of this programme.

During her address the Facebook COO highlighted how seriously the social network takes the issue of safety and reaffirmed the firm's commitment to tackling harmful content.
