He told the Stick to Football podcast: "I'm right at the bottom from a managerial point of view, and I want to work my way up.
"I'm not relying on what I've done as a player to get me into places that I shouldn't be.
"I would 100% (take a job in League One). I want to get back into managing and I want to prove myself. Whether that's League Two, League One or Championship. It's all experience.
"I'm only 38, I've had three managerial jobs. I've got quite a bit of experience, like with Derby in administration, and going out to the States (to manage D.C. United). I've got a bit of experience to lean on now, I'm still young in terms of a manager."
On what he's learned from past jobs, Rooney said: "I think I need to be stronger, and say that if we're going to do it, it's going to be my way... I've made decisions that will really push me and challenge me. I'm pleased with what I've done at Derby, pleased with what I did in DC, and it was disappointing for me at Birmingham. I think it's important that you go in to the right club at the right time."
