Internet service provider Digiweb will create 200 jobs over the next three years as part of its expansion plans.
The bulk of the jobs will be based at its new data and network operations centre in Blanchardstown, which opened yesterday.
Digiweb, which has headquarters in Dundalk, Co Louth, currently employs more than 120 technical staff in Dundalk, Dublin, Waterford and Limerick.
The new data centre will operate as the hub for the company's internet and broadband infrastructure. It will also serve as the base for the deployment of new technologies including Ireland's first fourth-generation, always-on mobile broadband network.
The network operations centre will provide 24-hour monitoring and response services for Digiweb's national wireless and fibre broadband network.
The expansion plans will include further work on the company's fibre network.
In addition, Digiweb said it would continue its expansion into markets outside Ireland. It trades mainly in Ireland, but also trades in Europe and the US. The company uses a mix of technologies to provide broadband and voice solutions in Ireland and Europe, particularly in Britain, Italy, France, Germany and Spain.
In February, the company announced that it had secured a mobile wideband licence in Norway. The licence and spectrum is identical to that which it secured in Ireland and will allow the service to be rolled out in Norway in 2008.
