Lloyds Banking Group is to create 500 jobs at a new tech hub in Edinburgh.
The bank said the hub would help transform the "digital experience" for Bank of Scotland, Lloyds Bank, Halifax and Scottish Widows customers.
It is creating 500 new software engineering roles in the Scottish capital, with recruitment taking place over the next 18 months.
The move is part of a £3 billion investment programme announced last year to boost the bank's digital capabilities.
"We're working with the industry to strengthen our tech-based talent pool in Scotland, which will not only benefit customers of Lloyds Banking Group, but support the development of technology, skills and talent in the fastest growing digital economy outside London," Philip Grant, chairman of Lloyds Banking Group's Scottish Executive Committee, said.
"People's expectations are rising rapidly as they want the same experience they're used to with established digital brands," Mr Grant said.
"In our tech labs, we are designing what customers will need in the future, making products and services that can adapt to their lives and making it easier for them to connect with their finances," he added.
Edinburgh is fast becoming one of the UK's most competitive tech hubs, with growth in agile start-ups, offerings from its world-leading universities and new digital academies providing greater scale and choice for careers in the industry.
