Very very unlikely to find a ski job in the south of England at any time. We have virtually nothing cause skiing just isn't part of the culture (understandably).
If you want to keep skiing through the summer the only nearby dryslope that does freestyle is calshot, which is on a wednesday evening I think (Billy Morgan is known to show occasionally)...
Or build a summer set up.
