I doubt if your son will get a good NIT with these marks. In case he does't get a good college on the basis of this rank, then he can opt for some of the good private universities like LPU, SRM, VIT, etc., offering various specializations in B.Tech. They have their different criteria for admissions. Some offer admission on basis of JEE scores, some offer admission on basis of their own tests and some offer admission on the basis of both. Some even offer direct admission on basis of your marks in class 12th. Some of the universities also offer scholarships on basis of your performance in class 12th or JEE or even during the course. All these universities offer world class learning atmosphere to students along with good placements.
Check their websites for more details.
Good luck.

A Bachelor of Science in Information Technology, (B.Sc IT), is a Bachelor's degree awarded for the completion of an undergraduate course or program in information technology.
A Bachelor of Science in Information Technology degree program typically lasts three to four years. This degree is primarily focused on subjects such as software, databases, and networking. In general, computer science degrees tend to focus on the mathematical and theoretical foundations of computing rather than emphasizing specific technologies.
In the job market B.Tech qualification carries more value. You can expect better job prospects as well higher salary after B.Tech. But it is important you select the specialization based on your career aspiration. For e.g. If you are interested in Botany then joining in an engineering stream is not the right decision. You should, in that case, pursue B.Sc too for better career prospects.
Regards.
