Here I am considering Nizam College , Hyderabad (On internet there are also some other Nizam College)
According to the documents furnished on placements  by the college authorities Chemical Companies as well as educational institutions like Aakash etc visit the campus and recruits students. So yeah you have scope obviously but no figures are given so the placement is 100% or not or how much students gets jobs in placements is not mentioned.

Now , you can apply for any government jobs exam like RRB NTPC , SSC CGL , IBPS PO , UPSC , State PSC etc and on qualifying you will get a job . But this are not scientific jobs . To work in organizations like ISRO , BARC etc you will require a MSc atleast for (Scientist positions / Scientific Officer). For Assistantship in the organization there can be some openings but they are not regular.

I hope my answer helps you. All the very best for your future endeavors!
