Wells Fargo in San Francisco said that its chief information officer will retire at the end of March.
Kevin Rhein, who was 61 as of the company's latest annual report, will leave Wells Fargo after more than 37 years with the company. In addition to his role as CIO, Rhein was also head of Wells' technology and operations group and was a member of its operating committee.
Rhein took on his current role in 2011 after heading the card services and consumer lending group.
A Wells spokeswoman declined to provide information on Rhein's successor as CIO.
Beginning in February, Wells will place responsibility for its technology and operations group's three main divisions under different members of the operating committee in preparation for Rhein's departure.
Chief Financial Officer John Shrewsberry will become responsible for the enterprise information technology division led by Scott Dillon. Dillon will be named chief technology officer.
