Technology firm Sanmina-SCI is to create 50 jobs through a €30 million upgrade of its Co Cork plant.
The US-based company, which makes ventilators and monitors for the medical industry, says it wants to transform the Fermoy plant into a research and development centre.
The facility employs 400 permanent and 200 temporary staff and is the largest medical unit within Sanmina-SCI.
Minister for Enterprise, Trade and Employment Micheál Martin said the move would consolidate employment in Fermoy and enhance the facility's position within the parent company.
