  Amazon.com Inc. said Jeffrey Wilke, chief executive for its world-wide consumer arm, will retire in the first quarter of 2021. 


  Dave Clark, the company's senior vice president for world-wide operations, will succeed Mr. Wilke, the e-commerce giant said. Mr. Clark joined the company in 1999 and started his current position in January 2013. 


  Mr. Wilke became consumer chief in April 2016 and previously oversaw consumer business, North American retail and world-wide operations. He joined the company in September 1999 as vice president and general manager for operations. 


  At Amazon, Mr. Wilke used his manufacturing expertise to help create a more efficient way of running the company's warehouses that made its two-day Prime shipping possible. He was also in charge of integrating Whole Foods into Amazon and was part of the leadership team that scouted for Amazon's second North American headquarters.
