Hello Jonas,
FTE jobs vary massively, and there will almost certainly be jobs you could do. The ATPL knowledge is very helpful - but the degree may or may not be a problem. "Aviation technology" is a title usually associated with very basic degree programmes that are really just there to satisfy USian requirements to have a degree for an airline pilot job and usually they contain very poor maths and science content compared to a more grown up degree in Aerospace Engineering.
Better still in the current environment, you'd want a degree in electronics or avionics.
But, given that each FTE job is fairly unique, and most organisations will look at everybody as an individual, there's certainly no harm in applying.
