Career Early career Mahoney worked as an attorney with the Harris Beach law firm as well as a criminal prosecutor in the Onondaga County District Attorney's Office.

County executive In February 2007, long-time incumbent County Executive Nicholas J. Pirro announced his retirement. Mahoney decided to run, but failed to win the endorsement of the Onondaga County Republican Party. The Republicans endorsed Dale Sweetland, Chairman of the County Legislature. The Post-Standard, the local newspaper in Syracuse; and Republican presidential-hopeful Rudy Giuliani, who is popular in upstate New York.

On November 19, 2007, Mahoney announced the names of her transition team that would ease the switch from Pirro's administration to hers. As she had promised on the campaign trail, it was a bipartisan team of Republicans and Democrats. The honorary co-chairs of her transition team were Republican County Executive Nick Pirro and former Syracuse Mayor Thomas Ganley Young, a Democrat.
Mahoney was inaugurated as Executive of Onondaga County on January 1, 2008. She was reelected in 2012, and again in 2016.
Presidency at SUNY-ESF In September 2018, Mahoney announced her resignation as county executive, midway through her third term, to take a position as chief operating officer with the State University of New York College of Environmental Science and Forestry (ESF).
