Now I'm interested in making my second character someone who grew up among the archeological digs of Tau Ceti, only reluctantly left in order to become an official archeologist like her parents, then joins the Arcadian for the chance that the ship meets descendants of those aliens or a new alien species entirely...Hmm...

Edit:
Thought for sure we had a xeno-archeology division under the civilian roles given that we do have alien ruins and the USF might expect more to be out there. Perhaps geology could work for her main job, or she could become a signals officer...

Also, I just noticed the astrogeography position. I'm presuming that those are the guys actually charting the star systems as they go? If no one applies for that role, could Martin also take up that position? That would suit him very well.
