The 31-year-old outside-half - who has scored over 1,000 points in Test rugby - is set to work alongside the new kickers in the Wales squad side such as Stephen Jones and Ceri Sweeney.
"Neil would be well suited for that job," said Wales coach Steve Hansen.
"He is obviously a great kicker but also his man management skills are very good and he can get his point across easily so that young and senior players pick it up.
"He will still have a role to play in Welsh rugby in the future as he enjoys working with young people, as we have seen at Pontypridd with Sweeney."
Jenkins has called time on his international career 12 years after making his debut against England in 1991.
Since then Jenkins established himself as the most prolific goalkicker in rugby history scoring 1,049 points in 87 Tests for Wales and a further 41 points in three Tests for the British Lions.
However he has been set back by injuries over recent seasons including a serious knee ligament problem that flared up during the 2001 British Lions tour.
"I think Neil has made the right decision. It's always the hardest decision to make after a long career but it's just a case of finally convincing yourself that your body can no longer do what you think it can," said Hansen.
"He has been a great player and a great ambassador for Wales and is revered around the world for the number of games he has played and points he has scored.
"But the man himself hasn't changed a bit, he's still down to earth and cares."
Jenkins will continue to play rugby at provincial level, however, having signed a one-year deal with the new Pontypridd-Bridgend region.
