Aircraft engineer reserves

Hi, im currently doing an aprenticeship in aircraft engineering and at the end i will have a b1 license.

Ive had a look on the website and it doesn't show a engineer position in reserves. Would it still be possible to join as a reserve as an aircraft engineer still. As im planning on moving to airbus at brize. to work on a400m or air tanker and ive heard you have to be apart of a reserve squadron to be able to deploy with the aircraft overseas.

Many thanks HR
