Job site Indeed has announced 600 new positions over the next five years at its new Capital Dock offices in Dublin.
The company started its Dublin operations in 2012 and it serves as Indeed's headquarters for its Europe, Middle East and Africa operations.
Indeed already employs over 1,000 people here.
The company said recruitment has already started for the new jobs, which include positions in marketing, finance, strategy, operations, sales, client services, HR and business development.
Indeed said today's announcement demonstrates the company's ongoing commitment to Ireland and the successful role that Dublin has played as its EMEA headquarters since 2012.
Indeed also announced a new partnership deal with the Irish Olympic team and said it would support the journey of all Olympic hopefuls as they aim for qualification and a place on Team Ireland.
Chris Hyams, CEO at Indeed, said the company exists to help people get jobs, and as the business grows rapidly, its need even more people to help with this mission.
"As the Irish economy has grown, Indeed has had the opportunity to grow a strong EMEA HQ here with an abundance of talented staff," he added.
Speaking on RTÉ's News at One, Mr Hyams said he believes that "any place that is an attractive place to live will attract a very talented workforce and that becomes a great place to build a business".
Mr Hyams said as businesses grow, some of those things can get more challenging.
"So far we have seen that in every step of the way our growth has been able to be matched by Dublin," he said.
He added that the firm have signed a long-term lease in Dublin and "are definitely here in Dublin for the long haul".
The Minister for Business, Enterprise and Innovation Heather Humphreys said it was very positive that a leading international technology firm such as Indeed will be significantly expanding its workforce in Ireland.
"The company's decision represents a real vote of confidence in Ireland as a place to do business and shows that the country remains highly attractive to overseas investors," the minister added.
IDA Ireland's Chief Executive Martin Shanahan said the company first came to Ireland just seven years ago to internationalise its business and to serve its growing customer base.
"In that time, Ireland has proven to be a superb location for the company to quickly expand its footprint into the EMEA market," Mr Shanahan said.
"Indeed's drive and ambition has resulted in it being the world's largest job site and Ireland plays a very important role in the ongoing success of the company," he added.
Foreign companies account for around one in 10 jobs among Ireland's more than two million workers, and hiring has shown little sign of diminishing in the face of Brexit and a slowdown in global growth.
Facebook said in January that it would hire 1,000 more people in Dublin this year.
And US cloud software maker Salesforce plans to add 1,500 jobs over the next five years, one of the largest job commitments in the 70-year history of IDA Ireland.
