The company is generating the positions in Dublin and Limerick in its cloud computing and solutions operations.
Cloud computing involves the on-demand provision of data or software via the internet rather than from a local computer.
Dell’s operations in Dublin will now host the computer giant’s first global cloud research and development centre.
The jobs in Limerick will form part of the company’s first solution centre globally.
Dell already employs 2,300 people in Ireland with 1,000 based in Limerick in and 1,300 in Cherrywood, Co Dublin.
The extra jobs will be rolled out over the next two years, with the recruitment of software engineers, IT architects, engineers and developers.
Announcing the jobs with the Taoiseach at Government Buildings, Dell vice-chairman Jeff Clarke said: “The decision to choose Ireland as the location for these global investments highlights the strategic nature of the operations that are already here and a testament to the quality of people that are on our Irish team.”
Mr Kenny said the extra employment showed the US group was committed to their investment in Ireland.
“It shows confidence in their operations here and that Ireland remains a good place to do business. This endorsement from such a global company is indeed very welcome.”
Dell cut its staff numbers in Limerick by almost 2,000 people in early 2009, when it moved its production unit to Poland.
Mr Kenny confirmed yesterday that the new jobs would not replace the old ones lost in Limerick.
Finance Minister and Limerick TD Michael Noonan said the previous Dell job losses had been a bad day for his home county but that the new employment was a sign of interest by businesses here.
