The system operators need to be Taertikon because they don't breathe air and don't need to eat. Since these machines can fix any issue without oxygen problems, you can remove the air from these areas when they catch fire. You can make them pretty indestructible if you give them Nano-machines.
The Rakkhi are Warriors capable of dealing with intruders or teleporting to other ships. Their fighting skills are among the best in the game. Engineers should be Etari because they can handle themselves in a fight and have enough health to last when fixing fires. Engineers are essential supporting roles, and it is better to have an Etari on hand as a spare crew member than any other race.
We don't have a Medic because it's not a very important role, and the Medbay can provide any healing.
