A total of 250 new high-skilled jobs were announced yesterday.
A leading US software firm promised to create 150 new jobs over the next three years in Cork.
Quest confirmed it was setting up a shared services centre in Mahon in Cork as part of an IDA-backed investment.
The 150 new jobs -- many of which will be for graduates -- will be created on a phased basis over the next three years.
Quest ranks as one of the world's leading software firms and boasts more than 100,000 customers across 80-plus countries.
The Mahon centre will help co-ordinate the development and expansion of its non-US business.
In the west, a multi-million euro investment is on track to deliver 100 high-skilled jobs.
The positions will be created over the next three years under a €17m expansion and research programme in the automobile parts firm, Valeo Vision Systems, in Tuam, Co Galway.
The company is injecting funds into developing hi-tech cameras used as aids for parking and manoeuvring cars.
Fergus Moyles, director of the Galway firm, said that recruitment was already under way for the 100 positions. He said the expansion in Tuam was "very significant".
