Walmart's US chief marketing officer, Stephen Quinn, is to retire in January after more than 10 years with the firm.
In light of the move, the retailer has announced that former Target marketing executive, Michael Francis, will join as a consultant at the start of 2016.
Most recently chief global brand officer at Dreamworks, Francis served at Walmart's rival for 26 years, and has also held the post of president at JCPenney.
His new role will see him tasked with revamping Walmart's marketing department. Commenting on the appointment, Francis said: “I’m committed to building on the strength of that brand, and I couldn’t be more excited about the opportunity."
There has been a string of new appointments from the supermarket chain this year. In June longtime chairman Rob Walton stood down and was replaced by Greg Penner and more recently it added Instagram chief executive Kevin Systrom to its board of directors.
