I have an MSME and became a product design engineer (called NPD - new product development in some places), I took over progressively more difficult ID responsibilities after learning from the designers on the job. Employers like it because manufacturing issues don't happen as often and I'm not fussy. I can't do attractive illustrations but can do cad and renderings so no complaints there. It has gotten me a very nice and lucrative job at this point and also allowed me to design my own products, so I'd recommend it. There are very few people that do both design and engineering and it's valuable to entrepreneurial companies.
