I’ve been working in the Bay for over a decade and this is what an on-call rotation is for. If you’re doing this every week and are not a founder quit your job.
Rotation helps, but as a more senior/experienced person on the team it's easy for things to be "elevated" up to you because person X couldn't figure it out, etc.
This should be a rare event. If it’s not it’s also a sign of immaturity and disorder. Not worth it, especially as a senior engineer.
