Kirsten has been appointed by the United Cricket Board of South Africa (UCBSA) as a mentor to new players joining the national and provincial teams.
The UCBSA has reached an agreement with the left-handed batsman to groom new players in the team. He may also be considered for a position in the selection committee, the Board said in a statement on Wednesday.
"He is ideally suited for the job," the UCBSA said.
Kirsten's main role would be to bridge the gap between players in the six provincial teams and the national side.
Kirsten retired from all forms of cricket after South Africa's unsuccessful tour of New Zealand last month, where the visitors lost the ODI series and drew the Test series 1-1.
