The Primary Entry Point: Scientist/Engineer ‘SC’
The main gateway for fresh engineering graduates to join ISRO is through the Scientist/Engineer ‘SC’ position. This role places you at the heart of India's space programme, working on cutting-edge projects ranging from satellite development to launch
vehicle technology. Recruitment for these posts is conducted by the ISRO Centralised Recruitment Board (ICRB), which announces vacancies across various disciplines like Electronics, Mechanical, Computer Science, and Civil Engineering. The role is designated as a Group 'A' Gazetted post, offering a prestigious start to a career in space science and technology. The starting basic pay is set at Level 10 of the 7th Pay Commission, which is ₹56,100 per month.
Checking Your Eligibility: Education and Marks
The foundational requirement for the Scientist/Engineer ‘SC’ post is a B.E./B.Tech degree or its equivalent in a relevant engineering discipline. ISRO specifies a minimum aggregate of 65% marks or a CGPA of 6.84 on a 10-point scale. This criterion applies to disciplines such as Electronics & Communication, Mechanical, Computer Science, Civil, and Electrical Engineering, among others. For certain recruitment cycles, ISRO also requires a valid GATE (Graduate Aptitude Test in Engineering) score in the corresponding subject. It's crucial for applicants to ensure their degree is from a recognised university and completed within the prescribed duration. Final year students are often eligible to apply, provided they can produce their final degree certificate by a specified date.
Age Limits and Nationality
To be eligible, candidates must be citizens of India. The standard upper age limit for applying is typically 28 years as of the closing date of the application. However, age relaxation is provided for candidates from reserved categories as per Government of India norms. For OBC candidates, the upper age limit is relaxed to 31 years, and for SC/ST candidates, it is extended to 33 years, particularly for posts reserved for these categories. Ex-servicemen and Persons with Benchmark Disabilities (PwBD) are also eligible for age relaxations according to government orders.
How to Apply: The Online Process
The application process for ISRO recruitment is conducted entirely online through the official ISRO 'Careers' portal. Candidates must first complete a one-time registration using a valid email ID and mobile number. After registration, you need to fill out the detailed application form, providing accurate personal and educational details. This includes uploading necessary documents like a recent passport-sized photograph and signature in the specified format. If the recruitment is based on GATE scores, you will be required to enter your valid GATE 2025 or 2026 score details. An application fee, typically around ₹250, is applicable for some candidates, while women, SC/ST, and PwD candidates are often exempted.
The Selection Process: GATE Score and Interview
ISRO employs a multi-stage selection process. Depending on the specific recruitment drive, this can involve a written test or direct shortlisting based on GATE scores. For recruitments based on GATE, candidates are shortlisted for the interview stage based on their scores in a 1:7 ratio. The final selection is then determined by performance in the personal interview. Some recent notifications have indicated a 50% weightage given to the GATE score and 50% to the interview performance for creating the final merit list. The interview is known to be rigorous, with a panel of senior scientists assessing the candidate's fundamental knowledge, problem-solving abilities, and passion for the field.
