Former Royal Bank of Scotland CIO for corporate and institutional banking (CIB), Scott Marcar, has joined Deutsche Bank as head of IT infrastructure.

Marcar will be responsible for designing, operating and modernising the German bank's infrastructure to improve security and drive greater cost efficiency.

He will join officially in October following his departure from RBS after seven years. He had previously held senior technology roles at JP Morgan Chase, after joining the investment bank in 1993.

Marcar is one of two appointments announced by the German lender, with Richard Shannon joining as Americas CIO and co-head of Group Technology & Operations (GTO) for the Americas.

Shannon joins after 20 years with investment bank Goldman Sachs, where he held the title of global head of web platforms technology.

He will support Deutsche Bank's compliance and regulatory technology initiatives, with the bank planning to hire 1,300 staff to improve its systems and controls.

The staff additions follow the recent hire of Michael Grimaldi, who joined from Goldman Sachs as CIO of corporate banking & securities and global transaction banking business divisions.

Both Marcar and Shannon will report directly to global CIO and global co-head of GTO, Kim Hammonds, who arrived at the firm from aircraft manufacturer Boeing in November 2013.

"Richard and Scott are strong technology leaders who will add to our deep bench of technical expertise," Hammonds said. "Their skills and experience will prove invaluable as the bank continues to enhance its IT platform while strengthening controls."
