Yes. We have subject matter experts too. That's something I have tried very hard to avoid from my college days to present. God has instilled in me a desire to be flexible. So I have successfully worked as a Quality Analyst, Welding Engineer/Supervisor, R&D Engineer, Plant Engineer, Manufacturing Engineer, Project Lead Engineer, Maintenance Engineer, Programmer, Chemical Engineer, Electronics Engineer, Piping and Vessel Stress Engineer, Project Lead Mechanical Engineer, Mechanical Design Engineer, Civil Engineer, Lo to Hi Mach Design Engineer, etc., and jobs I can't talk about. I get bored at four to six years and look to change jobs within a company. I'm doing Weights Engineering now and some documentation work on a fighter jet. It's not particularly exciting.
It's cool when you're allowed by management to think outside the box. Fixed processes are destroying engineering creativity. Engineers are now thought of as replacable components.
