Engineer

Doesn't mean every single men of science disapproved Sippe's plan, some were even totally okay to work for him.

He treats well volunteers : no brainwash, no torture, no forced work, eats well...

They recieved blue mechanic suits with a thermal protection coat and special shock absorbing helmet with night vision visor that has thermal vision option as well.
The most cases dislike unwilling to work scientists, thanks to their volunteerism they are overseer of those. They often got a small handgun for personal protection in the case of insubordination.
