Originally called in zone engineer (3)
I believe the answer is:
nee
'originally called' is the definition.
(written before eg a maiden name)
'in zone engineer' is the wordplay.
'in' says the answer is hidden in the clue.
'NEE' can be found hidden inside 'zone engineer'.
(Other definitions for nee that I've seen before include "Adjective meaning born, followed by maiden name" , "Adjective used to give woman's maiden name" , "Originally called" , "Born as (French)" , "Name originally" .)
