I left a job after a similarly short tenure (roughly 7 months) last year, but for different reasons: the product was essentially bait-and-switched on me. I thought I was being hired on to work on a problem I was really passionate about, and within a few months the business at large made it clear that they just wanted us to be be relegated to a "professional services" type arrangement. I think it's always okay to leave any job at any time for any reason; I once turned down a job at Google because the hiring manager was a complete asshole (I mentioned I had a dog and his immediate response was "oh god, I hope you never bring that thing into the office because I _hate_ dogs!"), I've left jobs because managers lied about petty shit, and I've left jobs because the company wouldn't allow me to work remotely despite several extremely senior eng leaders advocating on my behalf to do so. IMO, an engineering culture completely devoid of the ability to change is at least as valid as any of the ones I've had to leave, and I can tell you from personal experience that there's a limit to how much any one person can change, no matter their influence, the quality of their ideas, or their passion for righting the ship. At a certain point, you have to don your own oxygen mask before helping others. Especially if this job is impacting your mental health and/or personal life, cut and run right now. There's no reason to stick around for a job that's not giving you the respect you deserve.
