Is the post actually Senior Air Traffic Control Officer" (SATCO)or "Manager of Air Traffic Services" (MATS)?
The trouble with any air traffic unit is that it will always be a "cost" centre and never a "profit" centre for the airport company, and therefore the person running the unit has to be a very strong and persuasive person to get on - going funding, and that's where you need the business brain as well as the operational supremo.
To be SATCO you need to be a qualified air traffic controller, and usually, but not always, validated in all positions at the airport.
Manager of Air Traffic Services can, in theory, be someone with no air traffic experience, but to succeed and do the job successfully, they'd have to have the help of a very cooperative air traffic controller or SATCO, especially if the MATS was directly accountable to the CAA..
I'm not personally aquainted with a unit where the MATS is not a qualified or non operational ATCO, but unless a non atco MATS works very closely with a SATCO, it's a scenario doomed to failure.
