Setting aside the aviation specifics...
If you do not already have the right to live and work in the UK (which EU citizens no longer automatically have) then anyone wishing to employ you would need to justify a work visa exemption for you. Basically they would need to demonstrate that they needed to employ you because they could not fill the post with a UK resident.
It may be a long, long, time before the aviation sector recovers sufficiently for this to be the case.
Good luck.
