Deval Patrick has a new job.

The former Democratic Massachusetts governor will be joining the Boston firm Bain Capital to develop a line of so-called "social impact" investing to support causes from climate change to hunger.

Bain Capital was founded by Patrick's predecessor in the governor's office, Republican Mitt Romney.

Patrick told The Boston Globe ( ) that the opportunity is "a chance to have real meaning and mission in my work."

Patrick will become one of Bain's managing directors, sharing in the profits of the firm. He will be the first African-American to take on that role at the firm.
