Former Amazon Web Services (AWS) and Microsoft employee Tim Wagner has joined Coinbase as vice president (VP) of engineering, according to a blogpost August 6.

Wagner will now lead Coinbase’s engineering team, which is “central to [Coinbase’s] mission of creating an open financial system for the world,” Coinbase writes in the post.

Aiming to build the “most open, secure, and accessible financial system,” Wagner will also be responsible for expanding the team by hiring engineering talent in San Francisco, New York, and Chicago, according to his LinkedIn profile.

Prior to Coinbase, Wagner served as general manager (GM) at AWS for more than five years, with his most recent positions at AWS Lambda, Amazon API Gateway, and AWS Serverless App Repository.

Before AWS, Wagner spent several years at Microsoft, serving as the director of development at Microsoft’s Visual Studio Ultimate.

San Francisco-based crypto exchange and wallet Coinbase has also recently hired Wall Street exec Jeff Horowitz as its new Chief Compliance Officer, and Rachel Horowitz, who previously served at Twitter and Facebook as a communications expert, as the new VP of Communications.

Last week, Coinbase announced it started exploring the listing of 49 new assets on its custodial service, including storage for such cryptocurrencies as Ripple (XRP), EOS, Monero (XMR), VeChain (VEN), Cardano (ADA), Bitcoin Gold (BTG), and Telegram.
