Keep your head down, watch money appear in your account and get another job or see if you can transfer. You can’t do anything about a bad manager.

And don’t be naive enough to care about the “mission” of any profit seeking company. They don’t care about you and if you got hit by a bus tomorrow, they would have an open request for your job before your body got cold and would not remember you in a month.

Any FAANG size company sees you as just a number.

A job is a transaction - you give them labor and they give you money.
