I can recommend him for a position of responsibility as I have found him a very scrupulous young man.

Scrupulous means someone who is thorough, careful, and morally principled - paying close attention to details and doing things properly. Conscientious is the closest match, meaning showing care and conscientiousness in one's work. 'Hardworking' and 'enthusiastic' are positive traits but don't capture the moral/careful aspect, while 'conscious' simply means aware.
