Thermal Engineering

It depends on the college. You can ask seniors and check for placement records of last year of the college.
But There is enormous scope for thermal engineering. Any system which deals with temperature, needs a thermal engineer. As far as job is concerned, companies which manufacture heat exchangers, A.C.s, Refrigerator etc needs thermal engineers for designing such stuffs. You may also work in thermal power plants, hydro-electric power plant etc. Here you can work for designing the plant layout with your team or also go for monitoring and maintenance. If you want to do research, then sky is the limit. Hot research fields in thermal are: micro and mini hydel plants, cooling systems of nuclear power plant, alternate fuel for I C engines, Compact heat exchangers, cryogenics, thermal analysis of various systems, etc. There is a huge list. You just need to choose what you want to do.
