Crossword Genius

A post at headquarters (7)

Ross

I believe the answer is:

station

This clue is a double definition.

'a post' is the first definition.
(synonyms)

'headquarters' is the second definition.
(I've seen this before)

'at' acts as a link.

(Other definitions for station that I've seen before include "Small military base" , "Stopping-place" , "Broadcasting channel" , "TV or radio channel" , "HQ - stopping place - post" .)

I've seen this clue in the Evening Standard.
