Unfortunately no. I made the jump in 2022 from doing on-prem at a small company to doing on-prem at a hyperscaler when software engineers were very in demand and got placed in an organization which does physical datacenter design and core software infrastructure (software defined networking, service discovery, host management, datacenter failovers).

Back in 2022 you could make the moves, but I think now it is very hard to make the jump.

Part of the issue with building and running very large on-prem infrastructure is that you can only get experience by doing it. It not like you can run thousands of racks in multiple datacenters as a personal side project.
