That's kind of where my careers been, it seems like sre has been rebranded infrastructure and platform engineering and there's not to much sre titled jobs. It's probably not to hard if you have demonstrated experience with the expected sre tools. If you happened to have made the unforgivable sin of not using k8s or terraform durring your career it sucks.
They thing that sucks about k8s (and other industry software) is that you can't learn it without shelling out several hundred dollars on hardware. Sure you can read books, but that will be next to useless in the real world. We need something like an apprenticeship program or something that provides people access to learn.
I think two vps instances ought to be enough to get started with a light kube distribution.
I think SRE is a solid career pivot right now, especially if you have an overlapping skill set like mechanical/electrical engineering.
