In the Navy, "job" is determined not only by rank but rating. Master Chiefs performed and still do many important functions within the structure of the Navy as senior NCO's. Their jobs are varied, as they were during WW2 and before.

The master Chief Petty Officer rate was established in 1958, so there were no Master Chiefs in WW2. The rating MR is Machinery Repairman, which also did not exist in WW2. It is probably a split off from the WW2 rating MM or Machinist mate.
