Atom is recruiting 30 new employees for various positions, including two positions in the mortgage team.
Following the move from Durham to Newcastle, the bank is looking for two key people for its residential and commercial lending activities.
The commercial mortgage team is looking for a delivery lead who can help further improve turnaround times.
The residential team is looking for an associate pricing and trading manager who can focus on cost strategy and competition.
Of the 30 positions Atom is looking to fill, the lender also has vacancies across engineering, data, operations and customer support teams.
The bank says it will continue to support local initiatives and social mobility in the region through its early careers programme.
It includes the Atom Futures Fund, which provides financial support to low-income students and those in healthcare, helping them with college applications and transitions.
Atom’s headquarters recently moved to The Pattern Shop, a Grade II listed building previously occupied by Robert Stephenson & Co, a pioneer of the Industrial Revolution.
The building has been renovated to create low-carbon office space.
Atom chief executive Mark Mullen said: “Our move to the Pattern Shop is not just a change of address; it is a powerful statement about our future and our belief in the North East.
“We are investing in a space that celebrates our region’s industrial past while providing a modern, flexible and inspiring home base for our people.
“This new chapter will help us attract top talent and continue to challenge the status quo, proving that a truly innovative and profitable business can thrive here in the Northeast.”
