Barclays will cut around 1800 technology jobs in the UK over the next couple of years as it looks to offshore the work to "centres of excellence" around the world.
Staff at the bank's global infrastructure and service delivery (GISD) unit were informed of the plans in January, with the bank expected to shift the work to centres in India, Hungary and Singapore.
Of the 1800 permanent and temporary jobs, about 700 will be axed by September, with the remaining 1100 due to go by 2010.
Barclays says it needs "centrally-managed technologies in centres of excellence in key locations around the world" in order to become a fully global bank.
"These changes are about putting in place the technology and systems to support Barclays in achieving its ambitions," says a statement.
The bank claims many of the job losses will be among contractors and temps and it is working with union Unite to help permanent staff relocate or find work either within Barclays or externally.
The latest cuts follow plans revealed last May to cut 1100 jobs at Barclays UK processing centre in Poole, which handles back-office functions such as payment processing, human resources and IT support, over three years.
