The -reshape- idea is good. It can be slimmed
slightly:

reshape long w_job, i(ID) j(jobnum)
bysort id (w_job): gen Number_job = jobnum[_N]
reshape wide w_job, i(ID) j(jobnum)

but this solution, like Kelvin's, will return
any missing for each -id- as the maximum.
There are various ways around that; just be warned.

The calculation can also be done without a
-reshape-. We can also trap any missings that way.

gen max = w_job1
gen Number_job = cond(max == ., ., 1)
qui forval i = 2/4 {
replace max = max(max, w_job`i')
replace Number_job = `i' if max == w_job`i'
}

reshape long w_job, i(ID) j(jobnum)
gsort id -w_job
by id: gen Number_job=jobnum[1]
reshape wide w_job, i(ID) j(jobnum)
