The Indian Space Research Organisation (ISRO) has released the official notification for Scientist/Engineer ‘SC’ Recruitment 2026, offering 175 vacancies for eligible engineering graduates in Electronics, Mechanical and Computer Science disciplines.
The recruitment is being conducted through the ISRO Centralised Recruitment Board (ICRB) under Advertisement No. ISRO:ICRB:03(EMC):2026, dated 27 August 2026.
Eligible candidates can submit their applications online from 27 August 2026 to 16 September 2026, with the recruitment being based on a written test/CBT followed by an interview rather than a GATE-score-based selection process.
The advertised positions carry Level 10 of the Pay Matrix, with a minimum basic pay of ₹56,100 per month, along with applicable Central Government allowances and other benefits. The vacancies are distributed across Electronics, Mechanical and Computer Science streams, and applicants are required to have the prescribed B.E./B.Tech or equivalent qualification with the required academic performance.
Candidates should pay particular attention to ISRO’s eligibility rules because the organisation does not permit candidates to independently convert CGPA into percentage for meeting the minimum qualification requirement.
The official recruitment process also requires candidates to be registered on the National Career Services (NCS) portal before applying.
With applications now open, eligible engineering graduates should carefully review the discipline-wise vacancies, age limit, fee, examination pattern, selection process and document requirements before completing the online application.

Vacancy figures include backlog seats and are provisional; any revision will be notified via corrigendum on www.isro.gov.in. Allied disciplines acceptable under each stream are listed in the official FAQs — candidates from closely related branches should verify their eligibility there before applying.
CGPA / Percentage Rule — Read Carefully
- If your degree certificate/marksheet shows both CGPA and percentage, meeting either one of the two ISRO criteria is sufficient
- If only CGPA is mentioned, the CGPA itself must meet the 6.84/10 norm — converting CGPA to percentage using any university formula is NOT permitted for eligibility purposes
- The same rule applies in reverse if only percentage is shown
- For Dual/Integrated Degree holders: if CGPA/percentage is shown separately for Graduation and Post-Graduation, the Graduation-level figure is considered; if only a combined figure is shown, that combined figure decides eligibility
Age Limit & Relaxation (As on 16.09.2026)
- Maximum Age: 28 Years
- Age relaxation available for serving Central Government civilian employees, Ex-Servicemen, and Persons with Benchmark Disabilities (PwBD), as per Government of India orders
- PwBD candidates must submit a self-attested Disability Certificate (issued by a duly constituted 3-member Medical Board, with at least 40% disability) at the time of Interview
PwBD Reservation Categories
| Category | Disability Type |
| A | Blindness & Low Vision |
| B | Deaf & Hard of Hearing |

| D | Autism Spectrum Disorder, Intellectual Disability, Specific Learning Disability, Mental Illness |
| E | Multiple Disabilities (incl. Deaf-Blindness) |
Backlog PwBD vacancies may be interchanged across the five categories if suitable candidates from the originally notified category are unavailable; all PwBD candidates (Category A–E) are encouraged to apply regardless of the category shown against a specific post.

The “Academic Achievements” component rewards candidates from IITs/IISc/IIST/NITs/NIRF Top-20 institutes (3 marks), high CGPA/percentage (up to 4 marks), and institute-awarded rank 1–3 (up to 3 marks) — a distinctive feature not commonly seen in most PSU/bank recruitment interviews, so candidates from these backgrounds should be ready to highlight this clearly in their application and interview.
Selection Process & Final Merit
- Stage 1: Written Test/CBT (100 marks — Part A + Part B) at one of 37 venues nationwide
- Stage 2: Shortlisting for Interview in a 1:5 ratio (minimum 10 candidates) based on Written Test performance, category-wise
- Stage 3: Interview (100 marks) — Unreserved candidates need 50% in Written Test, 50% in Interview, and 60% aggregate; PwBD (reserved posts) need 40% + 40% + 50% aggregate
- Final Panel Weightage: 50% Written Test/CBT marks + 50% Interview marks
- Tie-Breakers (applied in order): (1) Written Test/CBT marks, (2) marks in essential qualification, (3) older candidate preferred by Date of Birth
How to Apply Online for ISRO SC Recruitment 2026
- Visit the official ISRO website — www.isro.gov.in and locate the ICRB advertisement link
- Candidates must be registered on the National Career Services (NCS) portal and meet eligibility conditions before proceeding
- Complete on-line registration to receive your Registration Number — save it carefully for future reference
- Enter a valid, correctly-spelled email ID — all hall tickets and call letters are sent only via registered email
- Fill in all application fields carefully and verify before final submission
- Upload photograph and signature strictly as per the specifications given below
- Proceed to pay the ₹750 processing fee via the Bharatkosh e-Payment gateway link that appears after form submission
- Avoid submitting multiple applications for the same post — only the application against which fee is received within the deadline is considered
Photo & Signature Upload Specifications
| Document | Format | Dimensions | File Size |
| Photograph (recent, colour, not older than 3 months) | .jpg/.jpeg | 200 x 230 px (preferred) | 100 KB – 200 KB |
| Signature (black ink on white paper, NOT capital letters) | .jpg/.jpeg | 140 x 60 px (preferred) | 80 KB – 150 KB |
- Photo must be against a light-coloured, preferably white background; no caps, hats, or dark glasses
- If wearing glasses, ensure no reflection and both eyes are clearly visible
- SC/ST/Disability/Ex-Servicemen certificate (any one, where applicable) must also be uploaded for full processing-fee refund eligibility
Documents & Other Requirements
- Candidates employed in Government/PSU/Autonomous Bodies must submit a No Objection Certificate (NOC) at the time of Interview — failure to submit the original NOC means the candidate will not be permitted to interview, and no Travelling Allowance (TA) will be paid
- All original documents supporting the online application details must be produced at the time of Interview
- Second-class train fare (shortest route) is reimbursed for Interview attendance only — no TA is paid for the Written Test/CBT
- Ration Card and similar non-photo documents are not valid proof for this recruitment
- PwBD candidates should get any manual disability certificate digitised on the UDID portal well in advance of verification
ISRO SC 2026 Preparation Strategy
- Part A (80 marks) decides the exam — since it carries 4x the weight of Part B, prioritise revising your core discipline (Electronics/Mechanical/Computer Science) fundamentals at final-year engineering depth
- Negative marking of −1/3 in Part A means guessing is costly — attempt only questions where you can eliminate at least 2-3 wrong options confidently
- Part B reasoning has zero negative marking, so attempt all 15 questions even under time pressure — there’s no downside to guessing here
- For Electronics: Focus on Electronic Devices, Analog & Digital Circuits, Signals & Systems, Control Systems, Communication Systems, and Electromagnetics
- For Mechanical: Focus on Thermodynamics, Fluid Mechanics, Strength of Materials, Machine Design, Manufacturing Processes, and Theory of Machines
- For Computer Science: Focus on Data Structures, Algorithms, Operating Systems, DBMS, Computer Networks, and Computer Organisation
- Since the final panel gives equal 50:50 weightage to Written Test and Interview, don’t neglect interview prep even if you clear the written round comfortably — Presentation/Communication Skill and General Awareness in your specialisation together carry 40 of the 100 interview marks
- Candidates from IITs/IISc/IIST/NITs or with high CGPA/percentage should be ready to substantiate these details clearly, since Academic Achievements is a distinctly weighted interview component in this recruitment
What Does a Scientist/Engineer ‘SC’ at ISRO Actually Do?
- Works on Research & Development activities in Space Applications, Space Science and Technology across ISRO/DOS Centres and Units
- Contributes to the design, development, and testing of Launch Vehicles and Communication/Remote Sensing Satellites
- Electronics stream: avionics, satellite communication systems, onboard electronics, signal processing for space hardware
- Mechanical stream: structural design, propulsion systems, thermal systems, and mechanical fabrication for launch vehicles/satellites
- Computer Science stream: mission software, ground systems, data processing pipelines, and simulation/control software for space missions
- Appointees are liable to be posted at any ISRO/DOS Centre or Unit in India and transferred based on organisational need
Common Mistakes to Avoid
- Attempting to convert CGPA to percentage (or vice versa) using your university’s formula to claim eligibility — ISRO does not permit this; only the criteria actually printed on your certificate/marksheet is considered
- Entering an incorrect or inactive email ID — since hall tickets and call letters are sent only by email, a wrong entry can mean missing the exam entirely
- Submitting bank account details incorrectly, which can cause the processing-fee refund to fail — ICRB/ISRO will not be responsible for such errors
- Uploading a photo/signature that doesn’t match the exact pixel dimensions and file-size range specified — such applications risk rejection
- Not being registered on the National Career Services (NCS) portal before applying, which is a stated pre-condition for this recruitment
- Ignoring genuine employer NOC requirements if currently in Government/PSU service — missing this at interview stage forfeits both the interview and any TA claim
