TSB is set to create more than 100 new jobs at its Sunderland contact centre.
The bank says it hopes to fill the vacancies inside the next six months - which will bring the total workforce at its offices at Sunderland Enterprise Park to around 600.
The company says the 114 new permanent TSB partner roles will cover various aspects of the business from general banking to fraud prevention.
Kerry Sharkey, head of telephone banking at TSB, said: "TSB is a key part of the local community in Sunderland.
"Our contact centre is performing extremely well and remains central to TSB’s growth plans.
"The new jobs will help us bring better banking to more people – meaning more people will benefit from TSB’s excellent products and services.
"We’ve always found a fantastic pool of talented, enthusiastic individuals in the local area and look forward to welcoming more into successful careers with TSB.
"We call all of our staff partners as their role is about working in partnership with customers, communities and across our branch networks.
"We are offering rewarding positions in financial services, which could cover anything from general banking and credit card services to fraud or lost or stolen cards."
Sunderland is home to the largest of TSB’s two main telephone banking centres, with the other based in Swansea.
The city is also a major hub for the contact centre industry, with the sector employing around 14,000 people and generating more than £200m annually for the regional economy.
TSB’s contact centre has been backed by Sunderland City Council’s business investment team.
Coun Mel Speding, Sunderland City Council Cabinet Secretary, said: "The bank’s continued investment in Sunderland is another boost for our flourishing contact centre sector and a vote of confidence for the city as a place to do business.
"We’re delighted Sunderland is playing an integral part of TSB’s national operations and we welcome the new opportunities this brings."
