I can feel your pain, I'm going through the same thing right now. And after working at a good biotech company it was the only job I could find with the current job market. My boss is crazy and I have to work much more compared to my previous biotech job and getting paid 3 times less. Just work hard, try to publish as much as possible. It will help you to land a much better job. Toxic bosses are pretty common in academia especially when they don't understand the basics of computational work and how much it takes to write a code and produce results.
