Keep an eye on God? That could be a job! (10)

I believe the answer is:

watchmaker

'a job' is the definition.
(I know that watchmaker is a occupation)

'keep an eye on god?' is the wordplay.
'keep an eye on' becomes 'watch' (synonyms).
'god?' becomes 'maker' (as in meeting one's maker).
'watch'+'maker'='WATCHMAKER'

'that could be' acts as a link.

(Another definition for watchmaker that I've seen is " One producing small movements".)

I've seen this clue in The Independent.
