ISRO SAC JRF/RA/PS-I 2026 — 48 Posts, Apply by 30 Sep (Gujarat)

ISRO SAC JRF/RA/PS-I Recruitment 2026 (48 Posts), Apply Online from 10 to 30 September 2026 in Gujarat. Space Applications Centre (SAC), Ahmedabad — a lead centre of the Indian Space Research Organisation (ISRO), Department of Space — has released Advertisement No. SAC:02:2026 inviting online applications for 48 temporary posts of Junior Research Fellow (JRF), Research Associate (RA), and Project Scientist-I (PS-I) across 16 post codes. This ISRO government job 2026 opportunity spans disciplines including semiconductor technology, RF & microwave engineering, VLSI, photonics, atmospheric sciences, oceanography, geophysics, remote sensing, GIS, and hydrology. Eligible candidates holding the post-specific B.E./B.Tech, M.E./M.Tech, M.Sc, or Ph.D qualification can apply online at sac.gov.in before the deadline. SAC is one of ISRO's lead centres, responsible for satellite-based communication, remote sensing, meteorology, and navigation payload development, and regularly runs fellowship-based recruitment to support its research and project pipelines. These JRF, RA, and PS-I positions are engaged for a fixed term only — JRF up to 5 years, RA up to 3 years, and PS-I co-terminus with the specific project — and do not carry any right to regular appointment at any DOS/ISRO centre, so candidates should treat this as a research-training opportunity rather than a permanent government post. Selected JRFs, RAs, and PS-Is will be posted at SAC, Ahmedabad, working on space-applications research projects, though project work may require travel or stay elsewhere in India. The ISRO SAC 2026 selection process is interview-based; if a large number of applications are received for a post, shortlisting is done on academic records and subject specialisation before candidates are called for interview. JRF applicants (Post Codes 01 to 07) must additionally hold a valid CSIR-UGC NET, GATE, or equivalent national-level qualifying score. The emoluments for ISRO SAC 2026 range from ₹37,000 per month plus HRA for first-year JRFs up to ₹67,000 per month plus HRA for senior-level Research Associates. The ISRO SAC 2026 online application is available at sac.gov.in and career.sac.gov.in. Online registration opened on 10 September 2026 at 1000 hrs, and the last date to apply for this recruitment is 30 September 2026 at 1700 hrs. There is no application fee for any post under this recruitment. Candidates must read the complete official SAC notification PDF before applying, since JRF posts carry a maximum age of 28 years while RA/PS-I posts allow up to 35 years, and all positions are temporary, project-based engagements with no claim to regular ISRO/DOS appointment.
