Utility contracting firm Gaeltec is to create 150 jobs in Kilkenny and Dublin, as well as on projects around the country.
The roles will include junior and senior engineers, field surveyors, fibre technicians, GIS technicians, supervisors, designers, electricians and plant operators.
The new jobs are the result of the firm securing a number of new energy and telecoms contracts in the utilities sector.
"Today's jobs announcement is a significant milestone for Gaeltec," said Gaeltec Managing Director, Joao Felizardo.
"Our expansion is a mark of the reputation we have built in the Irish utilities market, and the confidence our customers place in our high standard of work and consistent track-record of delivery."
60 of the new positions will be in support of SIRO’s roll out of the next phase of its fibre broadband network.
The broadband provider aims to bring Gigabit broadband to 770,000 premises in 154 towns around the country over the next four years.
"Our partnership with Gaeltec is a key part of our network build programme and the 60 new jobs at Gaeltec are a direct result of the massive shift in scale in our rollout," said SIRO CEO John Keaney.
Gaeltec is also currently working on several strategic electricity transmission and distribution projects.
As part of its expansion Gaeltec is investing €750,000 in the further development of its headquarters in Kilkenny.
The news was welcomed by Tánaiste and Minister for Enterprise, Trade and Employment Leo Varadkar, who said it is a real boost in the country’s capacity to build important infrastructure.
Gaeltec was founded 19 years ago and employs 200 people in Ireland as well as 100 more in the UK and Europe.
It is a subsidiary of Telecabo which itself employs 1,500 worldwide.
