CERT-In Scientist-B Recruitment 2026 Notification Out

If you’ve been sitting on a good GATE score wondering where it could actually take you, here’s a genuinely interesting option. The Indian Computer Emergency Response Team (CERT-In), which functions under the Ministry of Electronics and Information Technology (MeitY), has opened applications for 133 Scientist-‘B’ posts through Advertisement No. CERT-In/SCB/2026/1. These are Group-‘A’ equivalent positions, and unlike most government recruitments, there’s no separate written exam involved — your GATE 2024, 2025, or 2026 score does the heavy lifting. Online applications opened on 14 July 2026 and will close on 17 August 2026 at 5:30 PM, so anyone eyeing this needs to move with a plan rather than wait around.

CERT-In Scientist-B Recruitment 2026 Overview

Before diving into the finer print, here’s a quick snapshot of what this recruitment actually involves.

Things You Absolutely Need to Know First

• A total of 133 posts are up for grabs across Computer Science, Data Science & AI, and Electronics & Communication disciplines.
• There is no written exam — shortlisting for the interview stage runs purely on GATE scores from 2024, 2025, or 2026, with all three years given equal weightage.
• Zero application fee applies to every category, which is refreshingly rare these days.
• Final selection blends 60% weightage from the GATE score with 40% from the Personal Interaction/Interview.
• The job carries an all-India (and even overseas) posting liability, so mobility matters here.
• No prior work experience is required to apply.
• Interviews will be held in Delhi, and CERT-In has made it clear that no request for a location or date change will be entertained.

How the 133 Vacancies Are Split

CERT-In has broken the notified posts down by discipline, and Computer Science clearly carries the bulk of the opportunities this year. The Computer Science and Information Technology stream (GATE paper code CS) has 83 posts, split as 35 for Unreserved, 12 for SC, 6 for ST, 23 for OBC (NCL), and 7 for EWS, with three posts reserved horizontally for PwBD candidates. Data Science and Artificial Intelligence (paper code DA) carries 25 vacancies — 12 UR, 3 SC, 1 ST, 7 OBC (NCL), and 2 EWS, with one PwBD post. Electronics and Communication Engineering (paper code EC) rounds out the count with another 25 posts distributed as 13 UR, 3 SC, 1 ST, 6 OBC (NCL), and 2 EWS, plus one PwBD post.

Worth flagging: the SC and OBC (NCL) figures in the CS and DA streams include backlog vacancies, so those numbers aren’t purely fresh recruitment slots. CERT-In has also noted that the advertised post count is tentative and could shift up or down before the process concludes.

Who Can Apply CERT-In Scientist-B Recruitment 2026

Nationality

You need to be an Indian citizen, or a subject of Nepal or Bhutan, or a Tibetan refugee who settled in India before 1 January 1962, or a person of Indian origin who migrated from Pakistan, Burma, Sri Lanka, or specified East African nations with the intent of settling permanently in India. Candidates outside the citizen category will need an eligibility certificate.

GATE Score Requirement

This is really the backbone of the whole selection process. You must hold a valid GATE score in the paper code matching your discipline — CS for Computer Science and IT, DA for Data Science and AI, or EC for Electronics and Communication. Scores from 2024, 2025, and 2026 all carry equal weightage, so a slightly older score doesn’t put you at a disadvantage.

Educational Qualification

For the CS stream, you need either a four-year Bachelor’s degree in Engineering/Technology in a relevant field like Computer Science, IT, Cyber Security, Data Science, AI, Blockchain, or similar disciplines, or a Master’s degree in Computer Science, Computer Applications, or Computer and Network Security, or an MCA. The DA stream calls for a Master’s degree in a relevant Science discipline — think Data Science, AI, Machine Learning, Big Data Analytics, Cloud Security, or comparable fields. The EC stream wants either a four-year Engineering/Technology degree in Electronics, Telecommunication, Mechatronics, Robotics, or Drone Technology, or a Master’s degree in Electronics, VLSI Design, or related areas. One point CERT-In has been strict about: no “equivalent” qualification claims will be entertained, so your degree needs to genuinely fit the listed disciplines.

Age Limit

Age is calculated as on the cut-off date of 17 August 2026. The Unreserved and EWS categories get an upper limit of 30 years, SC/ST candidates get 35 years, and OBC (NCL) candidates get 33 years. PwBD candidates get considerably more room — 40 years for general PwBD, 45 for SC/ST PwBD, and 43 for OBC (NCL) PwBD. Service candidates already working in government roles get 35, 40, or 38 years depending on category, and an additional 5-year relaxation applies for those already serving in a Government organisation where prior experience would help in this role.

What the Job Actually Pays

Scientist-‘B’ at CERT-In sits at Level 10 of the 7th Central Pay Commission, translating to a pay scale of Rs. 56,100 to Rs. 1,77,500. That’s a solid starting point for a Group-A technical role, and it comes without the pressure of years of prior work experience — a fresher with the right GATE score and degree can walk straight into it. The notification doesn’t spell out specific allowance figures like DA, HRA, or TA, but as a Central Government Level-10 post, standard allowances applicable to central government employees would typically apply.

Application Fee

Here’s some good news for every applicant, regardless of category — there is no application fee at all for this recruitment. UR, EWS, OBC, SC, ST, and PwBD candidates all apply free of cost.

How Selection Actually Works

Since there’s no written test, the process runs in three clean stages. First, GATE score shortlisting happens in a 1:5 ratio, discipline-wise and category-wise, meaning five candidates are called to interview for every vacancy in each category. Anyone tied at the cut-off rank also gets shortlisted, so borderline scores aren’t automatically dropped. Second comes document verification, done ahead of the interview — miss this with your originals in hand, and you’re out of the race regardless of your score. Third is the Personal Interaction/Interview itself, worth a maximum of 50 marks and judged on technical/academic knowledge, presentation and communication skills, and your academic performance record (calculated at 0.05 marks per percentage scored in your qualifying degree).

The final merit list weighs your GATE score at 60% and the interview at 40%. There’s also a qualifying bar in the interview — Unreserved candidates need 50%, while EWS, OBC, SC, ST, and PwBD candidates need 40% — and falling short here knocks you out of the final list no matter how strong your GATE score was. If two candidates end up tied, the one with the higher GATE paper score wins, then the one with better technical marks in the interview, and if it’s still a dead heat, the older candidate gets preference.
