I've been a software engineer with a mild stutter for about 8 years now. From my experience it all depends on the company, the team and the clients you are working for. Some teams have lots of meetings, presentations etc, some don't. Also you have to understand that the more senior you become (and the more your salary increases), the more is expected from you - more meetings, presentations, mentoring juniors, participating in hiring interviews, onboarding new employees etc. I do struggle in meetings, but the way I survived all those years is by building a solid technical knowledge, constantly learning new things on my own and figuring out ways to not be easily replaceable. This is additional work, but I think that really becoming a specialist in your field is the best way to compansate for your stutter. Plus having a bunch of non-trivial side projects that can prove your competence in times when your words can't.
