Im not aware of any security related jobs that dont require experience in...something. Network, servers, software, or cloud. Typically security jobs will focus on a particular set of skills. For example, a network security job will be vastly different than an infrastructure security position. Security in general has many facets. A general security focused job would be something like a helpdesk.
With that said, here's a basic concept you should understand: who or what is the biggest security risk in an organization, and why?
