A green-tech Irish company and a technology firm are to create more than 40 jobs in separate investments.
M/A-COM Technology Solutions, a leading supplier of high-performance analog semiconductor solutions, is to expand operations in its Cork base.
Some 30 new staff are to be taken on at the plant, which acts as international headquarters and the centre for its integrated circuit (IC) design.
Sean Sherlock, junior minister in the Department of Jobs, Enterprise and Innovation, said: "IC design companies like M/A-COM Tech are of significant importance to Ireland's foreign direct investment portfolio.
"I wish the company every success in the future and offer the continued support of the Irish Government as M/A-COM Tech continues to grow its Irish operations."
In a separate jobs boost, Galway-based Cellulac has been approved for a record 2.8 million euro cash injection from the European Commission that will create 14 high-end jobs
The grant will be used to commercialise its biorefining technology that converts agricultural waste into lactic acid. The investment will fund 14 posts and the recruitment of graduates from the life sciences and engineering sectors.
Chief executive Fin Murray said: "This win and our confidence that Cellulac will be filling key R&D (research and development) roles locally is a testament to the investment poured into the development of the life sciences and green-tech sectors over the last number of years."
Elsewhere, five other companies have announced a total of 77 jobs.
European firms Culture Translate, Diaceutics, Nimble Apps, iMosphere and Unique Digital are to establish operations in Limerick, Dundalk and Dublin.
