Exclusive: Walmart's Chief Technology Officer leaves company as e-commerce wars flare

WASHINGTON (Reuters) - Walmart Inc. Chief Technology Officer Jeremy King is leaving the company, according to an internal company memo, even as the retailer races to transform its e-commerce business and close the gap with rival Amazon.com Inc.

King, who joined the company in 2011, led a revamp of Walmart’s U.S. e-commerce technology platform by making it faster, more competitive and customer-friendly, all of which have been key to the retailer’s fight against its e-commerce rivals.
