Scott Thompson, who served as the last official Yahoo CEO before Marissa Mayer (not including interim CEO Ross Levinsohn) has now taken the job of CEO at retailer network ShopRunner. He already has experience on the company’s board, and will be reunited with old colleagues.

Meanwhile, ShopRunner’s current CEO, Mike Golden, will continue as President of the company.

Golden said, “Scott and Michael Rubin had worked together for a number of years, and Michael and I took him through the idea of ShopRunner early on. He had an immediate understanding of the potential impact of ShopRunner for consumers and retailers. During his tenure as PayPal’s President, Scott joined the ShopRunner board of directors and we got to see firsthand how much value Scott could add to our business. Michael and I both felt he would be the perfect long-term CEO. We are thrilled that Scott has taken us up on our offer to lead ShopRunner’s continued growth.”

“Joining ShopRunner is a tremendous opportunity to build on the strong foundation that the company has already established,” said Thompson. “While PayPal and ShopRunner are fundamentally different businesses, there are similarities in each of their success. Both companies are focused on building the broadest network of satisfied merchants by providing the value that creates a large and loyal customer community, creating a virtuous circle.”

“Mike Golden has built a great foundation with ShopRunner and we both agreed that it is the perfect time to bring in Scott, who we have gotten to know extremely well over the past few years,” said Rubin, who currently serves as CEO of Kynetic, a majority shareholder of ShopRunner. “Scott’s deep understanding of online businesses combined with his team building, operational capabilities, and focus on product will allow ShopRunner to realize its ultimate potential.”

The ShopRunner gig may not be quite as high profile as Thompson’s short gig at Yahoo, but it may prove less of a challenge. Longtime Googler Marissa Mayer now has the pleasure of taking on the challenge that has cost numerous CEOs their jobs over the past decade.

Thompson had developed Thyroid cancer, which became public knowledge once the Wall Street Journal reported on it in May, but Bloomberg BusinessWeek reports that Thompson is now “cancer free”.
