A Prestigious Career Path
Working at ISRO is more than just a job; it's an opportunity to be at the forefront of India's space exploration journey. From the historic Chandrayaan missions to the ambitious Gaganyaan programme, ISRO scientists and engineers contribute to projects
of national importance. The Scientist/Engineer 'SC' role is a coveted Group 'A' Gazetted position, offering a chance to build a remarkable career in space science and technology. This high level of prestige and impact makes the recruitment process highly competitive, and understanding the eligibility requirements is the first critical step toward a successful application.
Core Educational Qualifications
The foundational requirement for an aspiring ISRO scientist or engineer is a strong academic background. For the Scientist/Engineer 'SC' post, candidates must possess a B.E., B.Tech, or an equivalent engineering degree from a recognised university. A consistent and high level of academic performance is mandatory. Applicants are generally required to have secured a minimum aggregate of 65% marks across all semesters or a CGPA of 6.84 on a 10-point scale. It's crucial to check the specific notification, as candidates in their final year of study may also be eligible to apply, provided they can produce their final degree by a specified date.
Eligible Engineering Disciplines
ISRO recruits for a wide array of specialisations that form the backbone of its technical operations. The most recent recruitment drive for 93 Scientist/Engineer 'SC' posts, with an application deadline of August 17, 2026, has called for candidates in several key fields. These include Electronics, Mechanical, Computer Science, Civil, Electrical, Refrigeration & Air Conditioning, and Architecture. Electronics typically has the highest number of vacancies, followed by Mechanical and Computer Science, reflecting the core needs of satellite and launch vehicle programmes. Applicants must ensure their engineering discipline exactly matches the one specified in the recruitment notification to avoid disqualification.
The GATE Score Requirement
For many recent recruitment cycles, a valid GATE (Graduate Aptitude Test in Engineering) score has become a key shortlisting criterion. The latest notification specifies that candidates must have a valid score from GATE 2025 or GATE 2026 in the paper corresponding to their engineering discipline. ISRO shortlists candidates for the interview stage based on this GATE score, not the rank or marks. According to the selection process, candidates are typically shortlisted in a 1:7 ratio for the interview. The final selection then gives equal weightage (50% each) to the GATE score and the performance in the personal interview.
Age Limit and Category Relaxations
Prospective applicants must meet the age criteria set by the organisation. For the general category, the upper age limit for the Scientist/Engineer 'SC' post is typically 28 years as of the closing date of the application. For the current recruitment ending August 17, 2026, this remains the standard. However, there are provisions for age relaxation for candidates from reserved categories as per government norms. Typically, OBC candidates receive a relaxation of up to 3 years (making the upper age limit 31), while SC/ST candidates receive a relaxation of up to 5 years (making the limit 33). Ex-Servicemen and Persons with Benchmark Disabilities (PwBD) are also eligible for age relaxation as per official orders.
How to Apply and Stay Updated
All applications for ISRO recruitment must be submitted online through the official ISRO website, www.isro.gov.in. The ISRO Centralised Recruitment Board (ICRB) is the primary body handling these large-scale recruitments. It is vital for aspirants to regularly monitor the 'Careers' section of the website for the latest advertisements, as notifications for different disciplines and centres can be released at various times throughout the year. When applying, ensure all details, especially your GATE score and educational qualifications, are entered correctly, as any discrepancy can lead to the rejection of your application. The current application window for 93 posts closes on August 17, 2026.
