Around 260 jobs are to be created at the Irish operations of technology companies Yahoo and McAfee.
The jobs were formally announced this evening after a meeting between Taoiseach Enda Kenny and senior executives from the two Silicon Valley companies as part of his visit to the US.
Yahoo plans to hire over 200 people for its Dublin offices over the next year in the areas of customer support, technology, HR, finance and operations.
Speaking after meeting Yahoo managing director Marissa Mayer, Mr Kenny said the new Yahoo jobs were an endorsement of the economic recovery Ireland has made and bodes well for continued foreign direct investment in Ireland.
Dan McCarthy of Yahoo Ireland said this morning that the company is going through a period of change.
He said some people have already been employed as part of the new drive.
"We have got quite assertive plans for these 200 roles so we have actively started over the last couple of weeks. We have actually some people on board now and we have significant targets to recruit these folks so we're live."
Meanwhile, security software firm McAfee will create around 60 engineering jobs at its centre in Cork.
Speaking at McAfee headquarters Mr Kenny said the Government was listening carefully to the comments made by companies investing in Ireland about the business environment and how it could be improved.
The new jobs are supported by the IDA.
