As many as 90 new jobs are being created in Belfast's Titanic Quarter by a worldwide software firm.
Fidessa, which is headquartered in London, plans to create the financial technology jobs.
The announcement will see an expansion of the firm's development centre set up in the city in 2008, supported with a £970,000 investment from Invest NI.
The company makes products and provides services for financial markets. It serves around 26,000 users across 900 clients worldwide and its products are used by many of the world's largest asset managers.
The new jobs will bring staff numbers at the Northern Ireland Science Park in the Titanic Quarter to 115 over the next three years.
Chris Aspinwall, Fidessa chief executive, said: "The Belfast centre has been central to the development of our new products and services for the international market and we have been delighted with the calibre of software engineers we have been able to recruit.
"This further investment will strengthen our development capability and enhance our reputation for providing powerful, robust solutions to meet the requirements of the most demanding blue-chip organisations involved in global financial markets trading."
First Minister Peter Robinson said the financial services technology sector is important to the local economy through high value jobs and export opportunities.
"This investment is a welcome confidence boost for the economy, which, as we begin this New Year, is still facing many challenges and will help to drive the growth and international reputation of the financial services sector in Northern Ireland," he said.
Deputy First Minister McGuinness added: "The investment follows recent investments by other internationally successful companies such as NYSE Euronext and First Derivatives and sends a very clear message to multi- national companies that this region has much to offer the global financial service sector."
And Enterprise Minister Arlene Foster said the availability of high quality software engineers and the company's positive experience at its Belfast operation had helped secure more jobs.
