Is it possible to do Graduate school full time in Engineering while working fulltime as an Engineer?

It sounds like a pretty tough load, but I know someone who went full time for a PhD in history in one university while going to law school in another university, so I guess your plan is conceivable. Good luck.

Full-time, no, unless your employer will let you work nights. Lots of people do master's degrees part time and most universities will have coursework-only master's degrees. Some major universities like North Carolina State even have their engineering master's degrees online. It might be possible to do that the equivalent of full-time.

You won't be able to do a PhD program or research-based master's though. The research project requires too much of a time commitment.

it is plausible for a individual to be self knowledgeable yet in lots of area even a individual with an engineering degree can no longer say they are an engineer till they are qualified by way of a particular technique.

Doubtful. Grad school classes etc are during the day, so is work. Most folks in my organization do grad school part time, including time off (with limits) for grad school classes held during the day.
