Suggestions on where to look for jobs in industry?

Hey all, I’m a current mechanical engineering student who will graduate at the end of this spring, I’ve had an interest in the engineering process of extractions, packaging, or really any work which requires an engineering skill/mindset. I haven’t had too much luck searching for positions so I was hoping some of you may have suggestions on where to look, as it is rather difficult to find job postings through most boards or find them on google. Thanks for your guys help and ideas
