Job given to vacuous engineer ahead of person who epitomises the qualities specified (6,4)
I believe the answer is:
poster girl
'person who epitomises the qualities specified' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'job given to vacuous engineer ahead' is the wordplay.
'job' becomes 'post' (post is a kind of job).
'given' means one lot of letters go next to another.
'to vacuous' says to hollow out the word (remove centre letters).
'ahead' becomes 'girl' (I can't justify this - if you can you should believe this answer much more).
'engineer' with its middle taken out is 'er'.
'post'+'er'+'girl'='POSTER GIRL'
'of' is the link.
Can you help me to learn more?
(Another definition for poster girl that I've seen is " iconic figure".)
