New York-based shared office rental company WeWork is shaking things up in its C-suite as it forges ahead with aggressive global expansion efforts.

WeWork's chief legal officer and chief operating officer, Jennifer Berrent, has been promoted to co-president as 31-year-old Eugen Miropolski steps up from a managing director role to serve as her successor.

Berrent, who retains her CLO title, now oversees corporate strategy along with WeWork's people and legal teams. Miropolski, the youngest executive at the company, will focus on fostering international growth and cross-cultural collaboration between WeWork's international offices.

WeWork has 425 locations in 27 countries, nine of which it entered last year, including Chile, Ireland, Japan, Peru, Spain and Vietnam. The company also is investing heavily in China and announced in February that it planned to open an office rental space later this year in South Africa. Nearly 60 percent of the company's shared workspaces are located outside the United States, compared with 41 percent last year.

Berrent joined WeWork as general counsel in 2014, when the company had about 250 employees—it has more than 11,000 today. She is credited with having “crafted a legal department that has served as the foundational support system for the company, establishing processes and policies that continue to support WeWork's unparalleled growth and expansion,” according to an email from a WeWork spokesman.

Before she went in-house for WeWork, Berrent was a partner for nearly nine years at Wilmer Cutler Pickering Hale and Dorr in New York, where she headed the firm's emerging company practice. She had an earlier stint as an associate at Covington & Burling and as associate general counsel for financial advisory firm Longitude Inc. She is a graduate of the New York University School of Law.

Miropolksi takes on the COO role after having served as the company's managing director for Europe, Pacific and China. He was Airbnb Inc.'s managing director of international operations before he joined WeWork more than three years ago.

He said in a prepared statement that as COO his “primary focus will be on serving—and scaling—The We Company mission to build a global community that offers our members innovative new ways to connect with both their physical environments and each other as they work, live, learn and play—whether they're in Jakarta or Johannesburg.”
