Boyd Johnson III, a former No. 2 at the U.S. attorney’s office in Manhattan, has left his role as co-chairman of investigations and criminal litigation at Wilmer Cutler Pickering Hale and Dorr in order to become general counsel at Soros Fund Management LLC, a private investment firm controlled by billionaire businessman and philanthropist George Soros.

Johnson officially starts at the investment management firm on May 1. He follows a well-worn path of former top federal prosecutors heading to prominent in-house roles at hedge funds.
