Oh, Kahl's already got hella practical experience with engineering, just not the numbers and principles behind it! All Grineer are cyborgs, and the vast majority of them live and work under pretty stark privation. They gotta learn really quick how to repair and jury-rig fixes for all their equipment, including their own limbs. They're also competent enough on average to bash together new devices out of existing tech they understand.

Still! Kahl has expressed a desire to learn about "science stuff", so he definitely won't turn down a chance to talk with somebody who knows more about the subject.

also he has no innate magical ability or magitek with him, so he'll be on the waiting list for that. He's just your regular, average, cyborg clone spaceman.
