There is a shred of hope left. I have a friend that has not offered me work personally but he says he loves the "Google reject engineers". Meaning he loves to hire the people that are phenomenal and confident enough to compete in the big league but are defeated by some small technicality such as checking the wrong box on a web based job application or in your case failing at "side channel" communication. That's probably more of a good quality for you rather than a failure.
This is the problem with society at large IMO.
Sounds like a toxic or at the very least an incompatible workplace. You should look for a different place to work, and possibly a different line of work entirely, since you don't seem to enjoy the "meaningless engineering". Money isn't everything.
