Seems to me that the "spy" was doing mandatory military service when he was 18 in the Intelligence part of the army? It seems common for many Israeli technically minded teens to go into that or similar wings rather than the more on the ground units.

It was from 1995 to 1998 (that's 20 years ago now) before he was at University and is the first item in his work experience. And the length of the position is about the same as military service. I do not know his current age.
