More than 100 jobs are to be created at Hewlett Packard in Galway.
The jobs will be in software engineering, testing and development. Recruitment will begin straight away.
Over 4,000 people are currently employed by Hewlett Packard in Galway, Dublin, Kildare and Belfast.
Enterprise Minister Batt O'Keeffe said HP had chosen Galway to create the 105 jobs because it was at the core of research and development for the firm's global operations.
The highly-skilled positions will include engineering jobs from graduate to PhD level and will involve working with the latest innovations in the information technology sector.
The company is also seeking technologists and managers at the European Software Centre in Ballybrit, which covers software and services.
