I currently am a systems engineer working specifically on email systems design.
And this makes you an authority about Weapons of Mass Destruction how? Even if you were doing email systems design for DuPont or the military, you'd have no authority to cite.
Also, if you were any good as a "systems engineer" they wouldn't have you working on email, that's a lower rung than even web backends. Whoever was responsible for cooking up Saddam's nasties in the 80s wouldn't even hire guys of your caliber as a floor manager, let alone as an engineer.
