The cover story is that Boehner will not be lobbying, the firm says, but instead "providing strategic advice to clients."
Last week, he joined the board of the tobacco giant Reynolds American. Board members at Reynolds American can make $400,000 per year in total compensation, according to The Wall Street Journal.
He is expected to make even more at Squire Patton Boggs.
Boehner will be joined at the firm by longtime aides John Criscuolo and Amy Lozupone, reports The Hill. His former deputy chief of staff, Dave Schnittger, and former policy adviser, Natasha Hammond, already work at Squire Patton Boggs.
“With Speaker Boehner joining our team, we're better positioned than ever to grow our brand throughout the world and to fully capitalize on our integrated global platform,” said Squire Patton Boggs CEO Mark Ruehlmann in a statement.
Boehner resigned from Congress last October.
