They hired you and have to take responsibility for training you. Don’t let they’re Byzantine development practices scare you. In all places that I’ve worked in like that - Jira sweat shops - the product was a tinderbox of disaster code waiting to burst into flames and nobody noticed. Everyone is chained to their Jira tickets - including the whole management hierarchy - and nobody bothers to look up to take a fresh look at the big picture. You have out-of-the box, novel experience and can help them far more than I think you realize… They need you. “Hey guys, do you really think this is a good idea..?”
