Describe your responsibilities in your first role, then do the same with each promotion. This demonstrates that you have grown into new roles and you have the potential to do so again. If you don't do this, you may look like a dead end.
Everything in a resume should be targeted towards the job that you're trying to land. Don't ever
just describe the responsibilities in your roles. This leads to lots of dead weight in your resume, and will make it less likely to get a response. Yeah, you should describe the job . . . but every part of the description of responsibilities (actually, every part of the resume itself) should link back to how you're going to be good at the new job you're looking for.
