Aristocrat Leisure has begun the search for a new chief technology officer (CTO) to replace the departing Andy Hendrickson.

Hendrickson has resigned and accepted a role at a competitor, having served as CTO of Aristocrat since July 2021.

His contractual obligations include a six-month notice period and Aristocrat has put in place interim leadership arrangements to ensure continuity while a “rigorous” internal and external search for a successor is completed.

“We thank Andy for his contribution to our business over the last four years and look forward to announcing his successor in due course,” said Aristocrat CEO and managing director Trevor Croker.

Prior to joining Aristocrat, Hendrickson served as CTO at Activision, Walt Disney Animation Studios and DreamWorks Animation.

Shares in Aristocrat Leisure Ltd (ASX:ALL) closed 1.60 per cent lower at AUD$67.10 per share in Sydney Thursday.
