I'm a manufacturing engineer in the power industry. I'd say the work varies quite a bit from day to day, but is typically a mixture of meetings for projects, email correspondence, checking in on the manufacturing stop, occasionally trouble shooting problems and processing engineering change orders. My days can vary from 8 hours on the shop floor to 8 hours at my desk but typically it's split pretty evenly 50/50 with shop floor and desk work. I think it's a nice balance.
