US e-commerce company Gilt, which employs over 150 people in Ireland, is to create 45 jobs.
The new positions will be in software engineering roles as the company establishes a Platform Innovation Centre in Dublin over the next two years.
The company said it will also add to finance and customer service positions in its Limerick office.
Speaking at the announcement in Gilt's global headquarters in New York, Minister for Jobs, Enterprise and Innovation Richard Bruton said: "E-commerce is a major growth sector that we have targeted as part of our plans for jobs and growth, and in recent years we have seen significant progress in this area.
"Gilt is a world-leading and highly innovative company in this sector 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."
Gilt Chief Executive Michelle Peluso said: "Our Platform Innovation Centre in Dublin will own and accelerate some of Gilt's most critical development projects."
