The Saha Institute of Nuclear Physics (SINP), 1/AF, Bidhannagar, Kolkata – 700 064, a grant-in-aid Institution under the Department of Atomic Energy (DAE), Government of India and one of India’s premier institutes of basic scientific research, has released Advertisement No. SINP/Estt./Advt./11/2026 dated 31 July 2026 inviting online applications for 62 vacancies across Scientific, Technical, and Administrative and Auxiliary categories on Direct Recruitment and Deputation basis. Posts include Scientist ‘C’ (4 specialisations, 5 posts), Scientific Assistant ‘B’ (6 specialisations, 8 posts), Technician ‘B’ (9 specialisations, 18 posts), Assistant Administrative Officer-I (Deputation, 1 post), Lower Division Clerk (7 posts), Security Guard A (8 posts), Work Assistant ‘A’ (11 posts), and Halwai-cum-Cook (4 posts). The online application portal opened on 31 July 2026 at 6:00 PM and the last date for submission of the online application is 15 September 2026 at 3:00 PM IST at saha.ac.in. The application fee is Rs. 500 for Scientist ‘C’ and Scientific Assistant ‘B’ and Rs. 300 for all other posts; Women, PwBD, Ex-Servicemen, and Deputation candidates are fully exempted. Pay levels range from Level 1 (Security Guard A, Work Assistant ‘A’) to Level 10 (Scientist ‘C’) as per the 7th CPC, with DA, HRA, and other allowances as per Institute rules.
Important Note: Five points from the official notification that candidates routinely miss. First, there are three separate deadlines – online application must be submitted by 15 September 2026 at 3:00 PM IST; the PDF application file must be emailed to recruit.staff@saha.ac.in by 18 September 2026 at 3:00 PM IST; and candidates applying through proper channel (Government/PSU employees) or for the Deputation post must additionally send a physical hard copy to SINP by 28 September 2026 at 3:00 PM IST – missing any one of these deadlines means rejection. Second, fee payment must be completed BEFORE filling the online application form – the transaction reference number is required as a mandatory field during form submission; you cannot pay after submitting. Third, SC/ST fee exemption applies only for posts reserved for the respective category – SC/ST candidates applying against unreserved vacancies must pay the applicable fee. Fourth, the EWS certificate must be issued for Financial Year 2025-26 and valid for 2026-27 – certificates from earlier financial years will not be accepted. Fifth, Technician ‘B’ (FRENA) involves working in a radiation zone on a 24/7 shift-in basis at the FRENA particle accelerator facility – candidates should be aware of the nature of duty before applying.
