Mullin had been advising Ranadive in an unofficial capacity since the Silicon Valley software magnate bought the team in May, including scouting ahead of the NBA draft. Ranadive also said he had sought Mullin's advice before hiring D'Alessandro, who worked under Mullin in Golden State's front office.
"Chris Mullin is an incredible addition to our organization," Ranadive said in a statement. "I have great respect for his accomplishments and understanding of the game. From day one, we have focused on making the Sacramento Kings a first-class franchise built for the 21st Century. Chris brings the experience, knowledge, and influence to help us achieve our ultimate goal -- bringing a championship to the fans and city of Sacramento."
Mullin was the general manager of the Warriors from 2004-09, including a memorable playoff run in 2007 when the team upset the top-seeded Dallas Mavericks in the first round. He was a five-time All-Star with Golden State, a member of the USA's gold-medal winning "Dream Team" in 1992 and was inducted into the Naismith Memorial Basketball Hall of Fame in 2011.
The 50-year-old Mullin had worked as a broadcast analyst for ESPN in recent years and often expressed interest in getting back in a front-office role.
"I couldn't be more excited about joining the Kings and playing a part in making this team a winner again," Mullin said. "I'm especially grateful for the unique opportunity to work in close proximity with a world-class ownership group led by Vivek Ranadive and the talented group of individuals assembled in our front office."
