Try:

select *, case when job_Order is null then 1 else 0 end as Rank
from job
order by Rank, job_Order, job_id

What I'm reading is this: The user will add a job on one page using job_id as the reference. You're question is how to sort the jobs on the career page? Can you not just "ORDER BY job_Order" when retrieving the data to display on the careers page?
