Credit Suisse (CSGN.S) named Goldman Sachs’s (GS.N) Joanne Hannaford as chief technology and operations officer as of Jan. 1, the Swiss bank said on Monday, as current chief operating officer James Walker takes a role in the United States.

Hannaford, who held senior jobs at Goldman Sachs Engineering in London and New York including co-head of Enterprise platforms and global head of resiliency, will become a member of Credit Suisse’s executive board, the bank said in a statement.

Walker, in the COO role since 2019, will become the deputy CEO of Credit Suisse Holdings (USA), Inc. and be based in the United States “for family reasons”, the Swiss bank said.

This is the latest top leadership change at Credit Suisse as it navigates its way through twin crises: the suspension of funds linked to collapsed British supply chain finance company Greensill and the implosion of investment fund Archegos. The bank has been hit by billions in losses and big declines in its share price.

“Technology is and will increasingly be a key success factor in financial services and with her skills, Joanne is well positioned to lead our strategic efforts going forward,” Credit Suisse Chairman Antonio Horta-Osorio said.
