Starting in 1983, Mr. Davidian spent the first years of his career at the NASA Lewis Research Center in Cleveland, Ohio, working for the Space Propulsion Technology Division in the area of analytical and experimental research on the performance of liquid rocket engines.

Between 1997 and 1999, Mr. Davidian was assigned by NASA to work as the Assistant Director of Operations for the Summer Session Program at the International Space University in Strasbourg, France. Upon his return to the center (which had been since renamed to the NASA Glenn Research Center), Mr. Davidian worked in the Plans and Programs Office.

In 2001, Mr. Davidian left government service and entered the private sector in many positions.

In 2004, a move to Washington, D.C. provided Mr. Davidian the opportunity to work on Centennial Challenges, NASA's prize program. He started as a contractor, working for WBB/DMG, and then reentered civil service when he was hired by NASA Headquarters in 2007, becoming both the Program Manager for Centennial Challenges and the ESMD Commercial Development Policy leader.
