Citigroup is creating 440 IT jobs at in a technology and operations centre in Belfast over the next five years.
The IT jobs are part of the banking group's plan to create more than 500 new roles.
According to the Belfast Telegraph, deputy first minister Martin McGuinness said, "Over the next five years, Citi plans to create 440 new high-quality roles in its technology and operations divisions and a further 61 new specialist posts in its legal and compliance division."
Government business support group Invest Northern Ireland contributed £8.4m to the project.
The investment signals that business volumes are on the up for banks. This contrasts with two years ago when the worst effects of the credit crunch were being felt. In November 2008, US bank Citigroup announced plans to cut its workforce by 52,000 jobs across all businesses and geographies.
Citigroup CEO Vikram Pandit said the bank would cut 20% of its employees at the group.
The latest figures from CWJobs.co.uk show that the financial services sector is advertising the most IT contractor and permanent roles.
