Fifty new software jobs are to be created in Belfast by the US-based ATG company.
The firm already employs 62 people in the e-commerce sector at its Belfast offices. ATG's clients include Tesco, B&Q and Tommy Hilfiger.
The move was announced on Friday by Enterprise Minister Arlene Foster.
"Generating upwards of £2 million in salaries annually, this is great news for the local economy and underscores Northern Ireland's position as a highly regarded investment location," she said.
"ATG has operations across the world but has chosen to locate these new jobs in Belfast because of the quality of the workforce it can access here and the support offered by Invest NI."
ATG Senior Vice President of Products and Technology, Ken Volpe, said that the company's experience in Belfast has been excellent.
"Our continued investment here reflects our confidence in our existing team and the calibre of local technology professionals we are looking to recruit.
"We consider our Northern Ireland office to be an integral part of our worldwide research and development operations, which plays a pivotal role in our overall company growth."
US economic envoy to Northern Ireland Declan Kelly welcomed the expansion.
"US technology firms of all sizes continue to look to Northern Ireland as a location for global expansion because of the talented workforce and expertise the region offers in technology and software development," he said.
