D.E. Shaw & Co. has hired Christopher Zaback as CFO and a managing director, assuming the title previously held by Stuart Steckler, who will retain overall responsibility for most firm-wide infrastructure.

Zaback joins D.E. Shaw from Sandelman Partners, where he served as co-chief operating officer and previously as CFO. Prior to that, he was a director and co-head of the middle office of Moore Capital Management and a vice president in the equities division at Goldman Sachs.

“We are very fortunate to have someone of Chris’s talents playing such a key role,” said Steckler. “His natural leadership abilities and fluency with complex financial reporting make him a great fit for the firm. As our infrastructure continues to grow to support our global business, his arrival will allow me to focus more time on strategy and execution of firm-wide initiatives.”

D.E. Shaw currently approximately $39 billion in assets and has offices in North America, Europe, and Asia.
