Some 165 new jobs are being created at two separate companies in Dublin.
The global telecommunications software company Ammeon is creating 75 new jobs at its global headquarters in the city.
The company is looking for software architects, senior software developers and business development specialists.
Meanwhile, IT company Version 1, is opening its new corporate headquarters on the city's Millennium Walkway, creating 90 new positions.
However, Version 1 is looking abroad to fill vacancies in its expansion plan, because it says it cannot get enough graduates here.
Managing director Justin Keatinge said the Government should make it easier to recruit from abroad.
"We're trying to bring people from all over the world...to fill these vacancies, and it's very difficult," he said.
"We would encourage the Government to come up with a fast-track, hi-tech work permit system where within a week you could get a work permit for a person coming from Argentina, for example."
