I have multiple journal articles, but I do not enjoy conference presentations. Is it bad for my job prospects?
[I am talking from a STEM perspective, not from social sciences, but from what I hear from humanities, interaction may even be more important there than in STEM. However, take it with a grain of salt:]
A faculty position involves interacting with people and giving lectures regularly. Where will you get the practice from if not in conferences?
Assuming even that you get a faculty position. Where will you get your networks that you'll need for tenure and promotion, if not by meeting colleagues at conferences and explaining your work. Yes, some extraordinary scientists may actually achieve faculty positions by their journal papers alone (I am aware of such examples), but they are extraordinary people and very rare.
Better, you face your challenge and get used to learn how to present good talks. We all had to develop this skill and I promise you it will come handy at some point.
