Manipulate mechanic? (8)

I believe the answer is:

engineer

I believe this clue is a double definition.

'manipulate' is the first definition.
(engineer can mean to plan or manipulate)

'mechanic?' is the second definition.
(type of engineer)

(Other definitions for engineer that I've seen before include "Person who uses scientific knowledge to solve practical problems" , "produced" , "control" , "Mastermind" , "He may be civil, mechanical or electrical" .)

I've seen this clue in The Independent.
