Bloom spent the past two and a half years advising President Barack Obama on manufacturing policy.
Recently, Bloom helped broker an agreement between the federal government and leading automakers to raise fuel economy standards to 54.5 miles per gallon by 2012.
Until Sept. 2009, Bloom served at the Treasury Department on the President’s Task Force on the Automotive Industry, helping coordinate the restructuring of General Motors and Chrysler.
“I am grateful to have been given the opportunity to serve under President Obama and alongside so many talented individuals who worked tirelessly to strengthen the economy and help communities across the nation,” Bloom said.
The White House said Bloom plans to return Pittsburgh to spend more time with his family.
