It didn’t take long for former Treasury Secretary Timothy F. Geithner to land a new job, and it’s not on Wall Street.

The Council on Foreign Relations, a nonpartisan think tank based in New York, said Wednesday that Geithner would become its newest senior fellow later this month. He stepped down as Treasury secretary Jan. 25.

President Barack Obama has nominated White House Chief of Staff Jacob J. Lew to replace him.

Geithner has followed this route before. He was a senior fellow at the Council on Foreign Relations in 2001 after his first stint at the Treasury Department and before he started a job at the International Monetary Fund. After the IMF, Geithner served as president of the Federal Reserve Bank of New York from 2003 until he became Treasury secretary in 2009.

Because of Geithner’s long history dealing with the financial industry and his role in the banking bailouts, some had speculated he might take a job on Wall Street.
