I am a solution architect now. I was a software engineer, then team lead, hired engineers then became an architect. Each to their own but I don't get how engineers can be effective without stand ups, meetings with stake holders and a frequent 1-2-1 with their manager. There are also demos, talking to vendors etc. As engineers progress they are expected to mentor juniors which typically involves pair programming and knowledge sharing. Some engineers, stutter or not, are pretty quiet. For any businesses I have worked in, it is the communicators that progress. I think software engineering is an excellent career for people who stutter in general with large periods of focused work. Everywhere I have worked, there has been that expectation to join and contribute to various calls.
