Well, there are product engineers, applications engineers, test engineers, product development engineers, product advancement engineers, VLSI engineers, AC power engineers, DC power engineers, MEMs engineers, a whole whackload.
If I crudely boil it down there is:
-microfab engineers (I'm not sure the exact word)- design the transistors on the silicon- not how they are arranged but the transistors themselves and the processes to manufacture chips
-VLSI/microelectronics engineers (design the transistors arrangements to make up ICs, microprocessors, RAM and all that).
-computer engineer (like the VLSI engineer except focuses on processors, RAM, buses and everything that makes them up)
-power engineers (power distribution systems and grids, generators, transmission lines, power plants)
-power engineer 2 (AC/DC motors, rectifiers, DC-DC converters, motor drives)
-control engineers (makes the stuff algorithms and hardware to control other things)
-electromagnetics engineer (lasers, magnetic fields, and atoms and crazy stuff like that)
-RF engineer (high frequency circuits like wireless and radio)
-communications engineer (I have no idea, but I know they exist I've not taken many courses in those)
And many more...
*chicks dig power engineers but my opinion is biased, but I found one that digs AI so...
