Harris, who was the club’s inaugural signing in BBL|01 and played in the Heat’s BBL|02 championship season, will join Brisbane as a specialist bowling coach for the first half of the season.
He will work alongside coach Darren Lehmann and assistant coach James Hopes, who were also part of the club’s BBL|02 championship.
Harris will depart before end of the BBL to complete his duties as Australia’s Under-19 coach for the ICC World Under-19 Youth Cup in South Africa early next year.
Experienced coach Gavin Fitness will also link with the Heat again during the BBL, having previously been involved with the club’s off-field staff as well as acting as a personal coach for Heat captain Chris Lynn.
Heat coach Darren Lehmann said he was delighted to work with Harris once more.
“We used Ryan as a bowling mentor early in the BBL when he was returning from injury, and I know Dan Vettori had him on his staff in a similar role a few years ago,’’ he said.
“I was lucky enough to captain Ryan as a grade cricketer, a rookie player and as a state cricketer. He was one of the most-talented players I had ever seen.
"We’re really pleased we can continue his growth as a coach as I know he has a lot to offer Australian cricket in that regard.
"It will be great to know he will be heading on from us to help the Australian Under-19 players pursue their dreams of a World Cup.”
“James Hopes and I are looking forward to having Ryan and Gav back with us and helping the Heat players execute their skills to the best of their ability and have some fun playing the game.”
Harris was a dominant figure for Australia as their pace bowler spearhead, claiming 113 Test scalps at 23.52 in a career curtailed by injury.
He played in the IPL with Deccan Chargers and King’s XI Punjab.
Since retiring in 2015, Harris has worked within Cricket Australia’s High Performance coaching program based at the Bupa National Cricket Centre and is currently Justin Langer’s bowling coach with the Australian team during the Gillette T20 International series against Sri Lanka.
Harris said he was excited to again be involved in the BBL.
“I really enjoyed my time as a player with the Heat, and it was where I got an opportunity to dip my toe in the water with regards to coaching,’’ he said.
“It’s another great chance for me to improve my coaching experience with ‘Boof’ and get ready to work with some of the country’s most talented young players at the Under-19 World Cup next year,’’ he said.
