aozc,
lads,
one of recruitment agencies recruiting for tk is sigmaaviationservices(dot)com.
currently looking for long haul SFOs and SFIs, I am sure they will have more positions (not just simulator trainers)
you can get more info directly from them: info(at)sigmaaviationservices(dot)com or recruitment(at)sigmaaviationservices(dot)com
best of luck
