Enzo doesn't have a job, he has a format, which is far more permanent and dedicated even than a career. Strictly speaking, he's a cadet, which is to say a student, but if something Guardianly comes up and no one more qualified is taking care of it (or even if they are), he is right there to take care of business.

Not sure what to say beyond that. The Guardian Collective has a sort of military structure, there's definitely some kind of chain of command (with version numbers instead of named ranks), but Guardians on solo assignments have a great deal of free rein in regards to how they pursue their functions.
