Well I am retired, (forced) do to movement of busines HQ.
I used to be in the Civil Aviation Authority, now AirServices Australia as a Flight Service Officer, Hence Exfso. This was/is very similar to Air Traffic Control. We used to service aircraft operations outside of controlled airspace, provide traffic information, Meterological service, in flight operational information, long distance HF communications for ATC, and search and rescue to name a few.
I did that for 30yrs.

That's my basic CV.
