Call centre company Eishtec is to create 250 new jobs at its sites in Co Waterford and Co Wexford over the coming months.
The company was developed less than two and a half years ago after the closure of Talk Talk in Waterford in 2011.
Starting just nine employees, the firm has grown significantly and currently employs 700 staff.
The customer contact provider recently won a contract to provide smart phone technical support in Britain and is therefore increasing its staffing numbers.
Supported by Enterprise Ireland, the project’s recruitment drive has already begun and the positions are expected to be filled by next summer.
Minister for Enterprise, Jobs and Innovation Richard Bruton said Eishtecis a “remarkable example” for the government’s plan for jobs and growth.
