400 new jobs are expected to be created by computer gaming company Goa in Dublin's Digital Hub. The company is the online games division of French telecommunications giant Orange and is owned by France Telecom.
The IDA backed investment is a significant boost for Ireland's high-tech sector, although it is not yet known how soon the jobs will come online.
Interactive entertainment is one of the fastest growing industries in the world and Dublin will provide a key base for the online games company Goa.
The company is a market leader in the cutting edge games industry and is about to produce a major new game for Mythic Entertainment.
The Dublin office will provide customer and operations support for European countries in five different languages.
The Tanaiste and Enterprise Minister Mary Couglan described the IDA backed expansion as 'terrific'.
She said the jobs were a very strategic inward investment and demonstrated the changing nature of our knowledge based economy.
