Generally, the guys with PhD degrees got the plum assignments, but I wrote my fair share of code for number crunching. I designed and built spacecraft antennas, but most of that software was long ago written by some senior guys. I did a fair amount of mechanical design, as well. That was all on me. If you are working for a US company, they are potentially limited in the tasks assigned to you, due to ITAR restrictions- "international trafficking in arms". That is a pretty far-reaching law, as it covers more than just "shooting" arms.
If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
