There are no direct recruitment program. You have to keep an watch on the ICRB website regarding the notice of recruitment for MSc Physics and you have to apply accordingly. Also I would recommend you to give GATE and apply for DRDO or BARC. BARC regularly recruits scientific officers every year which you can see in the BARC website but ISRO isn't regular and it publishes recruitments suddenly. So you need to pay attention.

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