Leaving Company in less than a year?

Recent college grad here. So, I was super excited to start my current job about 8 months ago. Initially I was told I would be trained and learn multiple things about the company and how they operate to be a process engineer mainly implementing continuous improvement initiatives. However it’s clear that is not what is going on. I’m being used solely for production with no guarantee to do what I want to do. I feel if I stay here any longer I will be setting back and damaging any potential career I have.

I’m being told by some older people it looks terrible to leave a job before two years, but I’m genuinely miserable most of the time. I wake up every morning dreading of going to work. I feel under appreciated and never taken seriously. The pay is ok for now at least for another year, but in my eyes the very minimum of what I would accept and ok benefits.
