135 jobs have been announced for Waterford.
A global publishing group is expanding its team in both Portlaw and Waterford City.
The Agora Companies - which currently employs 270 people - is celebrating two decades in the south-east.
The roles will be in digital publishing, software development and customer support.
“After 20 years in Waterford, we continue our commitment to Ireland’s south east which has established itself as a strategic location for a number of multinational corporations and continues to capture talent from the capital with the offer of a better quality of life," said Bill Bonner, founder of The Agora Companies.
"The Agora Companies have established themselves in communities globally and are driven by the same mission, to provide a source of responsible and genuinely independent advice and opinion.”
IDA Ireland CEO Martin Shanahan described the announcement as "terrific news for county Waterford and the wider south-east region".
He added: "Having a publishing group of this stature operate successfully from a regional location like Portlaw shows how global companies can establish and grow their operations in locations outside of large urban centres."
