Since Genetic Engineering is a highly research oriented field, a PhD degree is imperative if you want to climb up the ladder at work.
Genetic Engineering scientists and researchers usually find jobs in the research labs of universities and research institutions. Some even join the R&D section of biotech industries. Students with M.Tech or M.Sc degree in Genetic Engineering or Biotechnology with specialization in Genetic Engineering can find jobs in biotech and pharma companies or join universities as research assistants. Some universities in India also hire M.Tech/M.Sc students as lecturers.

First, there is no concept of 'placement' in US or other countries. The university is not responsible for the placement of its students and the reason why you are finding it difficult to search for this data is because there is no collated data for placements. The students find jobs on their own and the university doesn't keep a tab on their employment details.

Can you please explain your question?

Hi JP
Love to see you have set your future big and different.
I would suggest to go for Aeronautical / Aerospace Engineering from a renowned college then you may pursue higher studies on same. It will take you to close to your dreams.
One more suggestion, if possible just read the 'Wings of Fire' the autobiography of Mr. APJ Abdul Kalam. It will charge you up again.
