Adding a Job to defineJob.h

So I want to add a job to defineJob.h.

I want to add one new 1st job, one new 2nd job, one new Master and one new Hero. But the define IDs are all in numberical order, and I can't increase them all to include my new jobs, because messing up their original IDs make things happen in the game. Do each job type need to be within the MAX_ number? If I make a new 1st job can it be ID 32 or something like that, must I increase MAX_EXPERT to 32? It seems a bit strange

Code:

// Expert
#define JOB_MERCENARY               1 // 기본 직업들
#define JOB_ACROBAT                 2

#define JOB_MAGICIAN                4
#define JOB_PUPPETEER               5
#define MAX_EXPERT                  6
