Two Sigma Appoints Jeffrey Wecker as Chief Technology Officer

Wecker Joins Two Sigma from Goldman Sachs; He Succeeds Dr. Alfred Spector in the Role

Two Sigma announced that Jeffrey Wecker has joined the company as Chief Technology Officer and Head of Engineering. In this role, Mr. Wecker will drive technology strategy and implementation across the company’s businesses. He succeeds Dr. Alfred Spector in the role, who is retiring after holding the position at the firm since 2015. Mr. Wecker joins Two Sigma from Goldman Sachs, where he was a partner and the company’s first Chief Data Officer.

“Jeff brings an ideal combination of commercial experience, business acumen, and technical understanding of data analytics and architecture to Two Sigma,” said David Siegel, Co-Founder and Co-Chairman of Two Sigma. “Science and technology anchor Two Sigma’s offerings, and we look forward to leveraging Jeff’s unique expertise as we continue to grow the company.”

Of Dr. Spector’s retirement, Siegel said: “We are grateful for Alfred’s leadership and his many contributions to Two Sigma over a period of tremendous evolution for the company.”

As Chief Data Officer at Goldman Sachs, Mr. Wecker formed the firm’s Data Intelligence and Data Architecture departments and established data offices across Goldman’s divisions. These teams worked to bring together technology assets and data analytics with a specific focus on accelerating and improving data insights, quality and governance.

“I look forward to building upon the work of Dr. Spector alongside a group of innovators who are best-in-class within their respective fields,” said Mr. Wecker. “Data-driven systems have taken on increasing importance across financial services over the last decade, and Two Sigma is a true leader in developing and applying advanced quantitative methods to discover areas of opportunity.”

Prior to his time as Chief Data Officer of Goldman Sachs, Mr. Wecker served in senior roles at Bridgewater Associates — including Head of Front Office Transformation and Chief Business Architect — where he was responsible for the strategic transformation of the hedge fund’s investment engine. He previously served as Chief Executive Officer at Lime Brokerage and Townsend Analytics, Global Head of Electronic Trading at Lehman Brothers, and Co-Founder of Caspian Holdings, where he was Chief Executive Officer of Caspian Asset Management. Early in his career, he also spent over a decade at Goldman Sachs managing quantitative strategies.

Mr. Wecker received a Bachelor’s Degree in Civil Engineering from Princeton University, with a Certificate in Operations Research and Financial Engineering.
