Hewlett Packard is to create 500 jobs at its base in Leixlip, Co Kildare.
The jobs will be announced with the establishment of a global services desk.
The firm already employs around 4,000 people in Ireland at its bases in Dublin, Leixlip, Galway and Belfast.
Speaking on RTÉ's News at One Managing Director of Hewlett Packard Ireland Martin Murphy said the company has plans for further growth over the coming years.
The multi-lingual technical support centre will employ a range of people, including high-end graduates, and an element of the operation will also involve research and development.
300 jobs are to be brought on line immediately.
The new support service will deal with HP customers in 16 European languages.
The company says it decided to base the jobs in Ireland because of its access to a highly-skilled and talented labour pool.
However, some of its current staff have been affected by cuts with many taking leave in a bid to cut costs.
