Perhaps you are taking it too seriously. Sometimes "deadlines" are not really deadlines. I once work on a team exactly like the one you described: I was the new one and I was coming from a company that was obsessed with delivery something every week (even if that means delivering crap features). My new team was slow (for my then standards), it would take two days for the senior engineers to open a pull request about"adding a simple constant to an array"... But I after a few months I got used to that pace because: 1) we were delivering almost no (serious) bugs (which means we were never being paged at 3am), 2) it was a very relaxed environment, where I wasn't stressed at all (not like in my previous company).
