Online retailer Gilt. com says it will create 45 new at its Dublin office over the next two years.
The software engineering roles will be based at a Platform Innovation Centre in the capital.
The company also said that it will continue to add finance and customer service positions to its Limerick office as a result of the investment.
Gilt chief executive, Michelle Peluso, said that the Irish technology team has been "instrumental" in developing the company's e-commerce platform.
"We are excited by the opportunity to further harness the rich, deep talent pool available to us in Ireland, " she said. "Our Platform Innovation Centre in Dublin will own and accelerate some of Gilt's most critical development projects."
The venture is also being supported by the department of Jobs, Enterprise and Innovation (JEI) through IDA Ireland.
"Gilt is a world-leading and highly innovative company in this sector (e-commerce) which established its first European operations in Ireland in 2011, and today's announcement that it is expanding further with the creation of 45 high-end jobs is great news," said Richard Bruton, Minister for JEI.
Mr Bruton added that Ireland’s reputation is “strong” and that the country is “highly competitive”.
“We can see further jobs growth in the multinational sector in the coming months and years,” he said at Gilt’s global headquarters in New York.
Also welcoming the the announcement IDA chief executive, Barry O’Leary, said that the company’s Irish operations continue to go from “strength to strength”.
“Gilt will join many other companies in Dublin that have chosen to open software engineering operations here,” he said.
Gilt currently employs over 150 people in Ireland and first set-up operations in the country in 2011.
The company’s gross revenue in 2012 was just under $550 million, up from $450 million the year before.
