Social network giant Twitter is to double its Irish operations by taking on another 100 employees.
The company's European headquarters on Pearse Street in Dublin city centre is to expand by the end of next year with new staff taken on in sales, human resources, finance, marketing, engineering and user services.
It was one of two jobs announcements today after a 17.5 million euro (£14.8 million) investment was confirmed for the National Digital Research Centre which helps build and support high-impact new ventures.
The cash boost is expected to bring in 50 more jobs by the end of the year for digital companies.
Twitter made its announcement as it formally opened its European headquarters.
The company's managing director in Ireland, Stephen McIntyre, said the business has gone from one employee two years ago to more than 100 today.
"Twitter employees have a real opportunity to make an impact on the business," he said.
"Our users tell us that Twitter brings them closer to their interests and passions. We're also delighted to be working with thousands of businesses to help them find their voice online and connect with their customers in an engaging and entertaining way. This makes Twitter a tremendous place for talented professionals to make a difference and develop their careers."
Jobs Minister Richard Bruton said: " Twitter is one of the biggest names on the internet and one of the fastest-growing companies in the world.
"Twitter's decision in 2011 to establish its European HQ in Dublin was a major coup for Ireland and further confirmation of our status as the internet capital of Europe."
Twitter's presence in Ireland has been supported by the Department of Jobs, Enterprise and Innovation through IDA Ireland.
Barry O'Leary, IDA chief executive, said the investment demonstrates the confidence a global brand such as Twitter has in Ireland.
"This expansion solidifies Dublin's position as Twitter's second largest site globally," he said.
