Barclays Bank is to cut 400 IT jobs from its Global Infrastructure Delivery Unit, made up of 150 in-house jobs and 250 contractors.
The company said some jobs had become obsolete and others were duplications. Most of the job cuts planned are in Cheshire and London.
The bank said it would attempt to reduce compulsory redundancies through releasing contractors, closing vacancies and opening voluntary redundancy registers.
“Barclays continually reviews its operations and resources so that it functions as efficiently as possible as business needs and customer requirements evolve,” the firm said a statement.
“As part of this process, we have identified some aspects of our technology operations where the organisational structure impedes performance, and roles and responsibilities for colleagues are unclear.”
Other banks have been reducing staff numbers to position themselves for tough business conditions and back-office jobs have been hit.
Separately, about 450 jobs at womenswear retailer Viyella could be at a risk after the firm went into administration yesterday (7 January).
