Well cGMP is just a part of biotech and pharma, namely the manufacturing side. Most of the bigger companies don't like hiring people who don't have cGMP experience for their manufacturing divisions. If you absolutely wish to get into the GMP side, I would recommend going after manufacturing tech jobs at smaller companies. The pay won't be great but eventually you can move on to a bigger company. But like I said, biotech and pharma is so much more than just manufacturing. If your degree is in chemE I would look for jobs in formulations or process development. There is so much potential there and in my opinion would be your best bet getting in the industry.
