It seems being a fortran/assembly programmer is just a small part of whats needed. What they seem to need are engineers that can teach themselves quite deep domain knowledge of the voyagers to figure out how they work, reverse engineer the hardware and software that arn't documented. (and eventually do some programming, mainly on old ground based code, and certainly without bricking the probes if the flight software needs to be altered).
