"Do the work assigned to them" has multiple levels of abstraction. You could say it's the task level which would be entry level. You could say it's the project level which would be mid level. You could say it's the a service or domain which would be senior. Staff should be tackling org wide and cross-team issues. The amount of scope and clarity needed for a "problem" changes and gets larger in expectation and more terse in explanation the further you go.
