Senong will assist head coach Simphiwe Dludlu for the tournament, which will be played in Uruguay from November 13 to December 1.
Senong has been to a World Cup with his U-20 men's team in 2017, so Dludlu believes he will bring valuable experience to the side.
“We have appointed coach Thabo Senong as our technical director for the World Cup because we believe that we can learn from his previous experience,” Dludlu told SAFA's website.
“He is a well decorated coach who has passion for youth development. He has already joined our camp and has added a lot of value in the few training sessions we have had so far. We, as the technical staff, are very happy to have him here because he brings with him an opinion of experience.”
Maud Khumalo will continue working as Dludlu's assistant, making it a strong technical team for the showpiece.
“We are fortunate to have great minds of both coach Khumalo and Senong in the squad,” Dludlu said.
“We have a good working relationship and believe that we can reach our targets in Uruguay. I believe that Khumalo and I complement each other very well because I am her assistant at U-20 and she is my assistant at U-17.
“Coach Thabo has been a mentor to me,” Dludlu added. “With that said, I believe we have a very strong technical team going to this year’s World Cup.”
