You could join the Order of the Engineer and refuse to do things that would not be compatible with your understanding of the Obligation of an Engineer [1]. Of course, that doesn't stop your employer from asking someone else to do it and asking you to find other employment.

There's a few other orders or societies or what have you that you could join. Personally, I don't drive a train or even wear a stripey hat, so I haven't considered joining an organization for Engineers.
