DevOps is a philosophy, not a job role. It's the idea that developers deploy and operate their own code. An SRE is often someone who helps make that happen, by building the tools necessary for developers to operate their own code. In a small organization, you can get away with a sysadmin running a Kubernetes cluster to enable that. In a larger org you'll need SREs as well as Operations Engineers to build and maintain the tools you need to enable the engineers.
