Filled in top of form to get employed (7)
I believe the answer is:
infused
'filled' is the definition.
(infusing is a kind of filling)
'in top of form to get employed' is the wordplay.
'top of' says to take the initial letters.
'to get' is a charade indicator (letters next to each other).
'employed' becomes 'used' ('use' can be a synonym of 'employ').
The first letter of 'form' is 'f'.
'in'+'f'+'used'='INFUSED'
(Other definitions for infused that I've seen before include "as 27 [HERBAL TEA] did" , "Did steep" , "Inculcated" , "as the tea maker did" , "poured in" .)
