I worry about this every so often¹. On the one hand, I could probably get another job within the university (we're big on stealing each other's senior technical people). On the other hand, it's probably completely hopeless to apply for jobs outside the university, since I have (eg) basically no cloud/k8s/etc experience. If in-university jobs dry up or are unappealing, I'm up the creek.
(I'm not looking, I hope to spend the rest of my career at my current position.)
