The Minister for Enterprise, Trade and Employment, Micheál Martin has announced that IBM will invest €46 million in its technology campus in Mulhuddart, Co Dublin over the next three years.
The IDA-backed scheme is expected to create 300 jobs.
IBM already employs more than 3,200 staff in Ireland. This year the firm celebrates 50 years in Ireland.
Under the new investment, IBM is going to expand its software development operations, launch a business innovation centre and invest in its supply chain.
The company will be recruiting mainly graduate and doctorate level engineers to fill the new positions.
The software areas these new recruits will concentrate on include innovation in financial services, retail markets and biomedical research.
Work at the incubation centre will go towards identifying and advancing new business opportunities, in Ireland and abroad.
It is hoped the incubation centre will also be used by the wider research and development community.
