You've just described most jobs. From your username it appears you work at Amazon AWS. Guess what, most of the hard problems have already been solved. Every job needs worker bees; was this not clear during the interview? This is giving me "new grad wants to be CEO in a day" vibes. To quote comedian Louis CK, "Yes this job sucks, that's why we gave it to you."

So you're better off than most people as it is. My advice? Find a life outside of work. The worst feeling is the one when you blink and realize you've just wasted half your life working at a unfulfilling job, but you wasted your time and opportunities around the job. Make the best of what you have.
