Groupon has brought in a former Amazon.com Inc executive as its new chief financial officer, the discount coupon provider said.

Jason Child, a former vice president of finance for Amazon’s international business, took on the new role with Groupon on Monday.

Groupon turned down a $6 billion buyout offer from Google earlier this month, according to media reports.

The Chicago-based company’s viral couponing concept has been a hit, with annual revenue said to range from $500 million to $2 billion. It sends members daily e-mails with a variety of discounts. The deals are activated when a minimum number of people agree to make a purchase.

Child spent 12 years at Amazon after a seven-year stint at accounting firm Arthur Andersen.
