Frank needs a job. Take note! (8)
I believe the answer is:
postmark
'frank' is the definition.
('postmark' can be a synonym of 'frank')
'a job take note' is the wordplay.
'a job' becomes 'post' (post is a kind of job).
'take' says to put letters next to each other.
'note' becomes 'mark' ('mark' can be a synonym of 'note'**).
'post'+'mark'='POSTMARK'
'needs' acts as a link.
(Other definitions for postmark that I've seen before include "Frank" , "Stamp franking" , "Stamp cancellation" , "It is stamped on envelope" , "It shows date and time of mailing" .)
