Varied options must include one job (8)
I believe the answer is:
position
'job' is the definition.
(position is a kind of job)
'varied options must include one' is the wordplay.
'varied' indicates an anagram.
'must include' indicates putting letters inside.
'one' becomes 'i' (Roman numeral).
'options' anagrammed gives 'postion'.
'postion' going around 'i' is 'POSITION'.
(Other definitions for position that I've seen before include "Post or place occupied" , "Put" , "Spot" , "Office - location" , "brew" .)
