Ferrari protege Leclerc will graduate to the team from Sauber next year after just one season in F1.
Clear has been a leading F1 engineer for more than two decades and worked closely with multiple world championship-winning drivers including Michael Schumacher, Lewis Hamilton and Nico Rosberg.
It has previously been suggested that Clear could focus on Leclerc next year as Ferrari rejigs its technical structure in anticipation of the 21-year-old replacing 2007 world champion Kimi Raikkonen.
Carlo Santi has worked as Raikkonen’s race engineer this season following the departure of Dave Greenwood, while Riccardo Adami is four-time world champion Sebastian Vettel’s race engineer.
Asked ahead of this weekend’s Brazilian Grand Prix if he would be Leclerc’s race engineer next season, Clear said: “It’s not all finalised but at the moment, yes, I will have a strong influence on his side of the garage.
“Whether that is the job title or not, we’ll decide upon.
“Certainly I will taking closer attention to him than maybe I would have done on Kimi or Seb up until now.”
Leclerc has impressed with his rookie performances at Sauber but will arrive with only 21 starts and, at present, a best finish of sixth.
Clear, who recently made “a longer-term commitment” to Ferrari, believes his experience will allow him to make a good contribution to Leclerc’s adjustment to the famous Italian team.
“I have a lot of experience with young drivers and a lot of experience with experienced drivers as well,” he said.
“With Charles coming in I’ll help in any way I can to make his life easier, to ease some of the pressure, to make sure we get the best out of Charles and out of the team as a whole over the next few years.”
