No... I'm afraid I don't have a reference on job titles; even if I did, it likely won't be very meaningful; here's why:
Companies often create their own titles for positions that are all non-standard. Sure, there's the Network Engineer and the Systems Admin in IT; but many other positions are individually defined.
If you're able, the best way is to approach the company and simply ask them for a definition, or for further detail on the specific position of interest.
