If you think a Sr VP is going to take a meeting from a Sr Dev just to fire them because they tell them things they don't know or don't want to hear, I'd say you are being paranoid. Nothing I do in that meeting will be a fire-able offense. The reality is most Sr Managers crave hear honest feedback, as long as it's given in a respectful way. They may not agree, but they aren't going to take offense.

But if I'm wrong, and this Sr VP is one of the thin skinned exceptions (doubtful since they are taking the meeting from a Sr. Dev in the first place), then I can get a better job somewhere where it's less dysfunctional.

It depends on the exec. Most that I know like rough, raw feedback.
