RadioShack Corp.’s executive offices have some new residents. The struggling consumer electronics retailer has hired two new executive vice presidents as it continues to make changes to its senior leadership team.

Jennifer Warren is the chain retailer’s new executive vice president and chief marketing officer. She will lead all aspects of the retailer’s marketing, including online customer experience. Warren comes from the marketing agency world, having spent 12 years in various roles at GSD&M where she worked on accounts including Cost Plus Inc., eHarmony Inc., Zale Corp. and Hallmark Cards Inc. Most recently, she worked at agency Razorfish on the Samsung brand.

RadioShack also appointed Michael DeFazio as executive vice president of store concepts. DeFazio joins RadioShack from drug store chain Walgreen Co. In February, RadioShack’s CEO, Joseph C. Magnacca, also joined RadioShack from Walgreen. Magnacca says he’s worked with DeFazio since 2008.

“Jennifer and Mike are becoming members of the talented, world-class executive team we are building at RadioShack, all of whom have a focus on—and proven records of—transforming brands,” Magnacca says.

RadioShack’s previous CEO left in September. In December, the e-retailer hired Huey Long as executive vice president of strategy and consumer insights and Troy Risch as executive vice president of operations.
