Certainly, bad product management can make engineers unhappy. This includes failure to identify important features early in the development process; unwillingness to cut features to meet deadlines; waffling on what a feature should do so you end up rewriting the same thing several times, which feels like spinning your wheels; and probably several other things that come to mind right now. Plus, some engineers are motivated by seeing the software they build get used and solve problems for the users - bad project management certainly makes this less likely.
