It was brought to my attention that Nexus may have a roll as a sort of.. Hacker or Electronics specialist. The thought had completely escaped my mind as well, and I believe it is a wonderful idea. Being a robot, its defense and know how of electronics is unparalleled. I then further thought on other avenues, such as gunsmithing and equipment creation. While not being allowed in the ship-crafting or repair avenues, scouting teams or defense members could always use snazzy gadgets or high-powered weaponry, if scrap and materials were to be provided of course. 

In fact, if enough were supplied, heavy mounted artillery could be utilized by the machine itself, a large single-rig cannon perhaps.

But these are just ideas, you can restrict what Nexus is able to do. They would be more than fine being a Cyber-based defense platform.
