Robert Van Behren, co-founding engineer of the Google Wallet, has left his position with the technology giant as of January and joined the ranks of Square Inc. As you may remember, we have been following Square and founder Jack Dorsey as they acquire new talent for the start up.

Von Behren updated his Linkedin page today to read ‘Hyperspatial Payments Pioneer at Square’ under the employment overview section. His career at Google dates back to 2004 where he started out as a software engineer. He attended UC Berkeley from 1998-2006 as a PhD student in Computer Science, but never graduated.

Van Beren reports he is going to help Square expand its existing product line. Currently the start up has about 75,000 participating merchants. Direct competitors for the service include the Google Wallet, PayPal, and Intuit Inc.

Van Behren commented to NFC Times on his move to Square:

“When I left the Google Wallet project in January, I fully expected to stop working in payments but to remain at Google,”

“After meeting the team at Square, however, I decided to do the opposite. Square is doing some great things in the payment space. They have a strong leadership team and a culture that fosters innovation.”

At Square he joins Google ex-partner Jonathan Wall, former Tesla communications specialist Ricardo Reyes, former Apple executive Jesse Dorogusker, and Alyssa Cutright formerly of PayPay, now in charge of international business. With this lineup, Square is poised to revolutionize the way merchants interact with credit transactions.

We will be following Square as they continue to drive innovation in the mobile payment sector and we will keep you updated on changes at the start up. Dorsey has a goal to double their current staff of about 250 in the next couple of months so we can expect more talented addition to the team soon.
