(CNN) -- Mitt Romney will return to the private sector.
The 2012 Republican presidential nominee will join Solamere Capital, the investment firm founded by his eldest son, Tagg.
Romney will serve as chairman of the firm's executive committee, where he'll advise on matters of private equity, a source with knowledge of the situation confirmed Wednesday.
Romney has had office space at Solamere's Boston offices since the November election.
This story was first reported by NBC News.
The move is one more sign of Romney returning to post-election, private life. In December, he rejoined the board of directors at Marriott International, Inc., a position he held prior to his White House bid.
He'll re-enter the political sphere next week when he speaks at the annual Conservative Political Action Conference, a major conservative gathering held in the Washington, D.C. area.
