There are full time positions in the ANG. Each unit tends to handle them differently, but there is definitely a portion of every ANG unit manned with full-timers. Typically those positions are highly sought after but I've seen guys get hired as a part-timer and work their way into a full time spot.

There are two types: Technicians and AGR
Technicians are civil servants with a GS pay scale.
AGR folks are exactly the same as someone on active duty.

There are pros/cons to each that are well beyond this discussion. Bottom line, you could get hired at a Guard unit and eventually be there as a full time pilot.
