My opinion is: you should not think of your current job as something terrible you must leave asap. Make some token efforts to change the working environment if you have the say in the management or try to fit yourself for a few months.
Trying to change job is good, but you should have a solid backup plan first because the odds are against you, you are more likely to fail than to succeed going by general statistics. So you need to plan for failure, you should not "all in" even if you have a year of saving to spare.
It's really possible to have a shitty job but a good and meaningful life. Job don't control you, I am the captain of my soul. However especially while we're young there is no reason to muster a good effort to get a good job. Basically if you have a shitty job, you can still do quality things with your life, there is much to one's life outside a job, unless you are at a slavery shitty job.
Our normal day jobs leave us plenty of room to define our lives in other ways - how we treat people, who we get to know, what we do in our spare time, what we see in life and our surroundings. Quality of life is more dependent on self than on external parameters. Irregardless of your peers and your product at work, you can believe in causes like FOSS and fight for it in your spare time, you can get involved in charity and community work, you can read and think and define your way of life, you can get to know people and treat them in different ways. The source of happiness to, variedly, helping other people, being part of something greater than yourself, feeling collective purpose, and other things in that ballpark and if we believe them, then all of those are possible in almost any kind of environment
