Core Educational Qualifications
The primary eligibility criterion for the Scientist/Engineer 'SC' post is a strong academic background. Candidates must possess a B.E./B.Tech or an equivalent qualification in specific engineering disciplines. The most commonly sought fields are Electronics,
Mechanical, and Computer Science, though vacancies also open up for Civil, Electrical, and Architecture. To be considered, you must have secured a minimum aggregate of 65% marks across all semesters or a Cumulative Grade Point Average (CGPA) of 6.84 on a 10-point scale. This requirement is consistent across most recruitment notifications. It's crucial that the degree is from a recognized university and completed within the stipulated duration of the course.
Age Limit and Relaxations
For general category candidates, the upper age limit to apply is typically 28 years. However, the Government of India's reservation policies provide for age relaxations for other categories. Candidates belonging to Other Backward Classes (OBC) are usually given a relaxation of three years, making their upper age limit 31. For Scheduled Castes (SC) and Scheduled Tribes (ST) candidates, the relaxation is five years, extending the age limit to 33 years. It is important to note that these relaxations apply only against posts specifically reserved for these categories. Additionally, serving government employees, ex-servicemen, and Persons with Benchmark Disabilities (PwBD) are eligible for age relaxation as per government orders.
Nationality Requirement
A non-negotiable condition for applying to any position at ISRO is that the applicant must be an Indian citizen. This is a fundamental requirement for a role in an organisation of national strategic importance. All candidates will be required to produce valid proof of citizenship during the document verification stage of the recruitment process.
The Two Paths to Recruitment
ISRO primarily recruits Scientist/Engineers through two distinct methods. The first, and most traditional, involves a written test conducted by the ISRO Centralised Recruitment Board (ICRB), followed by a personal interview. The written test is designed to assess your technical knowledge in your specific engineering discipline. The second method, which has become more common, is recruitment based on a valid Graduate Aptitude Test in Engineering (GATE) score. In this process, candidates are shortlisted for a personal interview directly based on their GATE scores in the relevant paper. For a recent 2026 recruitment drive, for instance, ISRO announced it would shortlist candidates using valid GATE 2025 or 2026 scores, with the final merit list giving 50% weightage to the GATE score and 50% to the interview performance. Candidates must always check the official notification to understand which method is being used for a particular recruitment cycle.
How to Find and Verify Opportunities
All official recruitment notifications are published on the ISRO website, www.isro.gov.in, under the 'Careers' section. This is the only reliable source of information. Aspirants should be wary of fake job offers and always verify details on the official portal. When a recruitment drive is active, the website provides the detailed advertisement, eligibility requirements, application link, and important dates. For example, a recent notification for 93 posts had an application window from late July to August 17, 2026. Regularly checking the official website is the best way to stay informed about upcoming opportunities and ensure you have the most accurate information before applying.
