This is true, but around here a lot of those jobs are what one of my professional circles calls "adult supervision", and I feel 30 is a bit too young to be targeting those.
Having said that, I've seen teams of fresh grads and bootcamp trained devs, where some 30 year old adult supervision might have saved projects or companies from expensive or existential disasters. "No, we are NOT going to build this critical project's frontend on the JavaScript framework you and two of your bootcamp buddies spent the last 4 weekends writing."
More than anything I think the OP just needs a change of atmosphere and even as an IC with technical management or a middle people manager somewhere stable he’ll have an interesting time with a very different environment.
