Hello Dharamvir,
You have done your Diploma. Hence logical reasoning says go for engineering. But in engineering you may have to leave your job for three years. On the other hand BCA course, even if for three years, can be perhaps done alongside your job. Provided of course the college where you seek admission has classes that do not clash with your working hours. Best wishes to you.
