Being an M.Tech degree holder, you will not face any problem in getting job afterwards. There are many industries, plants and laboratories are recruiting Chemical engineers every year in India as well as abroad.
You can work in Mass product firms, refining industries, Petrochemical plants, Pharmaceutical plants and may more. There are different departments for chemical engineers like Quality control department, research and development department, Quality assessment department, etc. You can select any of them as per your interest and ca try for that. But one point you should keep in mind is, most of the higher designations for R&D, QC-QA departments are offered to PhD qualified candidates as they have research experience and aptitude to perform well. If a candidate is not holding PhD degree but have some research experience in some short term projects in relevant field, they are also considered.
So, my open advice is to pursue some good projects and get experience first and then try to get in reputed firms. This will give you good opportunities.
Apart from all these, teaching is an excellent option for reputed job with good returns. In this field you ca easily keep yourself updated with all the advance techniques in your own field.
You can start you tuition classes and this will give you freedom and independence to work in your available hours. So you ca think about it and convince yourself for teaching.
