Cabinet Secretariat DFO Recruitment 2026: 250 Technical Posts, Apply by Post by 15 November

Cabinet Secretariat DFO recruitment 2026 offers 250 tentative posts of Deputy Field Officer (Technical) in the Government of India, and the closing date is close: applications must reach the Cabinet Secretariat by ordinary post by 15 November 2026. The notification, Advertisement No. 02/2026, was published in the Employment News issue of 17 to 23 October 2026, and it fills a Group B, non-gazetted post in Level-7 of the pay matrix, with initial monthly emoluments of about Rs. 1,00,000 including all allowances for a posting at New Delhi.

Read the eligibility limits first, because they narrow the field sharply. Applicants must be Indian nationals, must hold a valid GATE scorecard with qualifying cut-off marks in GATE 2024, 2025, or 2026 in the paper matching their subject, and must not be over 30 years of age as on 15 November 2026. Each applicant may apply for only one of the nine subjects, and the degree subject and GATE paper must match. There is no online form, so an applicant who waits for a portal link will miss the deadline.

Cabinet Secretariat DFO recruitment 2026: subject-wise vacancies

All 250 vacancies sit under the single post of Deputy Field Officer (Technical), split across nine subjects, and the notification marks the figures as tentative. Computer Science and Information Technology carries 112 posts, with GATE paper CS, and Electronics and Communication or Telecommunication also carries 112 posts, with GATE paper EC. Data Science and Artificial Intelligence carries 10 posts, with GATE paper DA, Physics 5 posts, with GATE paper PH, Mechanical Engineering 4, Civil Engineering 3, Chemistry 2, Mathematics 1, and Statistics 1, with GATE papers ME, CE, CY, MA, and ST respectively.

The notification gives no category-wise reservation split and no Persons with Benchmark Disabilities breakup, so applicants should not rely on any split figure read elsewhere. The Cabinet Secretariat may revise the number of vacancies at any stage, and may cancel or withdraw the process without giving a reason. Shortlisting is done subject by subject, so a GATE score is compared only with others in the same paper.

Who can apply for the Cabinet Secretariat DFO posts

Applicants need a Bachelor's degree in Engineering or Technology, or a Master's degree in Science, in one of the nine subjects, from a recognised university or institution. A valid GATE score means the applicant achieved the qualifying cut-off marks in GATE 2024, 2025, or 2026 in the paper for the subject applied for, and all eligibility conditions are counted as on 15 November 2026.

The maximum age is 30 years as on 15 November 2026, with relaxation for Scheduled Caste, Scheduled Tribe, Other Backward Classes, Central Government employees, and ex-servicemen as per Central Government orders in force. The notice does not state the number of relaxation years and does not mention a minimum age, so applicants claiming relaxation should check the official notification rather than assuming a figure. Persons in government service must send the form through their office with Annexure-IV if they claim age relaxation.

Pay, posting, and service conditions

The post sits in Level-7 of the pay matrix as a Group B, non-gazetted post, with initial monthly emoluments of about Rs. 1,00,000 including all allowances for a posting at New Delhi. The notification does not give the basic pay amount or allowance details, so those figures should not be guessed from the total. The job involves field postings with All India transfer liability, and the medical standard will follow the Central Government guidelines for Group B posts.

How selection works for the Cabinet Secretariat DFO posts

Selection starts with a merit list. All applications received by the closing date that meet the eligibility conditions are arranged in order of merit on valid GATE score, separately for each subject. Shortlisting is set at five times the number of vacancies in each subject, and shortlisted candidates are called for interview, with the date, time, and centre sent by email. Final selection is based on the GATE score and the interview, subject to eligibility, character and antecedent verification, and medical examination. The notification does not state the interview marks or weightage, so applicants should not assume a ratio.

How to apply for the Cabinet Secretariat DFO posts by post

This is an offline process with no registration portal, and the steps leave little room for error. Applicants should copy the form printed in the notification, type it on A-4 size paper in English capital letters using black or blue ink only, fill every column, affix a self-attested recent passport-size coloured photograph, and sign the declaration. Self-attested copies of Matriculation, 10+2, and degree mark sheets and certificates, proof of date of birth, the valid GATE scorecard, and the Aadhaar card must be attached, with a caste certificate in Annexure-I or II if age relaxation is claimed, and a no-objection certificate if employed. Two recent passport-size coloured photographs, with the applicant's name and date of birth on the back, are also required.

The completed form must be sent by ordinary post to Post Bag No. 001, Lodhi Road Head Post Office, New Delhi-110003, so that it reaches that address by 15 November 2026. The date that matters is receipt, not the date the form is dropped in a letter box, so applicants should post early and keep the postal receipt. A form that is unsigned, incomplete, or missing a photograph or certificate will not be entertained, and more than one application, or an application for more than one subject, risks rejection. No application fee or payment mode is mentioned, so applicants should not send money with the form unless the official notification asks them to.
