Dear Candidate,

Yes certainly but from relevant streams/subjects. One with Ph.D. will be employed as a scientist/engineer with an ‘SD’ grade. For more details: Recruitment In ISRO - Eligibility For ISRO Exam & ISRO Employment Opportunities A bachelor's level degree in relevant subjects is required to write the exams for a job in ISRO.

Ph.D. holders have to register (for being considered when there is a vacancy in the corresponding field)

Hope it was helpful.
