The 17-year-old midfielder looked like a seasoned pro as he ran the show against Ross County in last week's 4-2 Scottish Premiership win.
The Scotland Under-19 cap scored the Tannadice club's third in Dingwall before setting up striker Nadir Cifti for the fourth.
But despite featuring in all but one of the Arabs' matches so far this campaign, McNamara has no concerns that his raw youngster will be burnt out by too much exposure to top-flight football.
Asked if he may need to protect Gauld at times this season by dropping him from the side, McNamara said: "That will depend on Ryan and how he is doing,
"If he is playing well then I won't take him out of the team to protect him. If he's coping and remains confident he will stay in the team.
"However, if the team is struggling then, like any of the players, I will look at how he is doing and decide what is best for him.
"Protecting players is not something I've had to consider yet. For me, they young lads in the team here have all shown they can handle it.
"If I saw signs that they weren't, then I would try and protect them as much as I can. I'd make sure they are were getting down and letting that effect their performances.
"But we have a very good group of young players who are all level headed and Ryan is one of those."
