hi,

see time to time there is many recruitment going in isro. for several past years they are recruiting for computer science, electronics, electrical, and mechanical engineers. but there is always possibility that they will hire other stream engineers also. for making a satellite their is many technologies needed and also the qualified person need to present their for supervise. see if you want to pursue chemical engineering and really passionate about it then join any good college, dont think about job prospect of view right now as rather than isro , there is many organization who hires chemical engineers, some example as ongc, iocl, barc, sail, ntpc etc.
