The challenger bank is set to continue to increase its headcount outside of London, after announcing a transition to profitability earlier this year.
Starling Bank is set to recruit 100 new staff for its Southampton office, as part of a hiring drive.
Southampton was the challenger bank's first office outside London and was initially launched in 2019.
The new hires will be based in the city's Town Quay business hub and will work across a variety of different business functions, including customer services, compliance, software engineering, and data analytics.
Anna Griffin, talent acquisition manager at Starling Bank, said the bank is happy to recruit people who haven't worked in banking previously.
"We're really focused on people who just really want to provide the best customer service," she added.
The announcement comes as the challenger has been hiring at a rapid pace.
In contrast, Monzo's headcount moved from just 1,332 to 1,879 in that same period.
Much of this hiring is occurring outside the capital; in May, the bank more than doubled its headcount in Cardiff to 868, after initially pledging to hire just 400 people in the region.
Starling's expanding headcount mirrors an expanded lending portfolio.
Mortgages accounted for £1.2bn of Starling's loan book as of March 2022, but that figure grew to over £2bn in June.
Despite the majority of financial services jobs still being concentrated near London, Starling isn't the only major employer boosting its headcount outside the capital.
In addition, Bank of London is set to create 232 jobs in Northern Ireland with the opening of its new Belfast office, across job functions such as software engineering, compliance, and risk.
