Target Corp. continued this week replenishing its e-commerce and information technology leadership team with outside talent, as it seeks to recover from a devastating data breach last year that exposed the credit or debit card details of 40 million customers and other personal information of 70 million shoppers.

The retail chain announced yesterday it had hired Alan Wizemann to the newly created position of vice president of Target.com and mobile product. He will oversee digital teams for Target, No. 18 in the 2014 Internet Retailer Top 500, (more on the Top 500 ), and report to Jason Goldberger, who remains as senior vice president of Target.com and the company’s mobile team. Wizemann has been consulting for Target and leading various product teams, including the one responsible for Target’s Cartwheel mobile app. He previously founded e-commerce software provider ShopIgniter.

The company also announced hiring David Weissman to head up Dermstore, the online retailer of skin care products that Target acquired last year.  Weissman previously worked at BCBG Max Azria Group Inc., where he was executive vice president of e-commerce and omnichannel. He also held senior-level positions during a 10-year tenure at GSI Commerce Inc., which was acquired by eBay Inc. in 2011.

Target also announced yesterday that it had hired Jim Fisher as senior vice president, Infrastructure and operations at Target Technology Services, where he will oversee Target’s technical infrastructure and operations. He most recently worked at payment processor First Data Corp. and previously held positions at The Home Depot, Macy’s and IBM.

These three appointments follow several other senior-level hiring of executives from outside of Target. They include: Brad Maiorino, hired as senior vice president and chief information security officer; Peter Glusker, senior vice president, New Business Integration and Operations; and Kristi Argyilan, senior vice president, Media and Guest Engagement.
