The professions are: Armortech, Weapontech, Biotech, Chemist, Inventor, Harvester, and Soldier for Hire. The article goes into some detail about each profession's specialty and gives a bit of information about materials gathering and the collection of schematics to assist characters.
Check out all there is to know (so far!) on the Prime: Battle for Dominus site.
