Rueda, 60, replaces Ze Ricardo, who was sacked after the side's 2-0 home loss to Vitoria on August 6, reports Xinhua news agency.
The six-time Brazilian Serie A champions are currently seventh in the 20-team standings with 29 points from 20 matches.
Rueda has previously coached the national teams of Colombia, Ecuador and Honduras. He had been without a club since June, when he parted ways with Colombia's Atletico Nacional, whom he led to the Copa Libertadores title in 2016.
His first match in charge will be a Copa do Brasil semi-final clash against Rio de Janeiro rivals Botafogo on Wednesday.
