According to a report from CoinDesk, Tim Wagner, VP of Engineering at Coinbase is leaving the company after just over a year at the job. Wagner previously spent six years at Amazon Web Services and joined Coinbase shortly after the company acquired Earn.com and made Balaji Srinivasan CTO. Srinivasan left Coinbase in May along with COO Asiff Hirji meaning Wagner is the third senior departure from the firm in just a few months time.
