Telecoms company Rainbow Communications is to create 20 jobs at its Northern Ireland base.
The company said the expansion is linked to the announcement this week by mobile phone company EE that it plans to open a customer contact centre.
As the only direct business partner of EE in Northern Ireland, Rainbow Communications said the new posts will be in sales and will bring the total number employed by the business telecoms provider to over 100.
Stuart Carson, director of sales and marketing at Rainbow Communications, said: "We have witnessed significant growth in the past year, not least in our mobile offering due to our partnership with EE who is the only provider of 4G services in Northern Ireland.
"EE's commitment to Northern Ireland is clear following its announcement to create 250 jobs in Belfast earlier this week and its continued expansion of the 4G network in Northern Ireland.
"The creation of these 20 new jobs is a significant investment for Rainbow. We are committed to providing expertise and value wrapped in a customer service second to none."
