After a couple of years in a decent grad school, passing quals, many times thinking about quitting (the usual: impostor syndrome, stress etc), and one paper. I feel like I have a clear head to make this decision. I do not want continue with a career path in academia, I want to be an engineer (or other technical field). In short, I will be happier that way and need to support my family with a better income.
I love physics and it will always be a part of my life and would love to still work with it. Currently, I work in experimental condensed matter: know a lot of fabrication techniques, studied lots of mechanics, can build circuits and perform fairly complicated electronic measurements, written programs for analysis (mostly Matlab, but some C in the past). The list can go on... I feel like the transition with this track record shouldn't be hard - but I don't want to be misinformed or get too "cocky".
What can I do to be a competitive applicant that will have to contend with people that have engineering degrees and training?
