Sears Holdings (SHLD) said its president and chief merchant, Luis Padilla, would leave at the end of the month.

Sears said it is "evaluating leadership alternatives" and that a search for his replacement is under way. Padilla was brought in last year by former Sears chief Alan Lacy. Lacy was kicked upstairs earlier this month in favor of Aylwin Lewis, a lieutenant of investor Ed Lampert, who controls Sears.

Sears also named Maureen McGuire marketing chief, Corwin Yulinsky head of customer strategy and insight and David McCreight president of Lands' End. The retailer said the execs would report to Lampert, who is chairman.

McGuire joins Sears from IBM ( IBM), where she was vice president, strategy and marketing, worldwide systems and technology group. Yulinsky joins Sears from McKinsey, where he was a leader of the financial institutions practice.

"These two experienced and highly effective executives will bring Sears Holdings a new level of creativity and focus on marketing and our customer relationships," said Lampert. "I particularly value the winning attitude and record of success that they will bring to Sears Holdings, and I expect them to help lead the on-going change in Sears' culture."

Sears said McCreight has been acting as interim president of Lands' End since Aug. 4. He joined Lands' End in 2003 as chief merchant.

"David has moved quickly to inject energy into the Lands' End organization and to foster collaboration with Sears Holdings," Lampert said. "With David's background and experience, we look forward to his leadership in extending and expanding the Lands' End brand with the quality, value and service that it has long been known for."

On Wednesday, Sears fell 81 cents to $117.98.
