Recruitment Overview
The Space Applications Centre (SAC), a premier operational center of the Indian Space Research Organisation (ISRO) in Ahmedabad, has opened its recruitment process for 40 research positions under Advertisement No. SAC: 02:2026. Covering Junior Research Fellows (JRF), Research Associates (RA), and Project Scientist-I (PS-I), this drive targets engineers, physicists, meteorologists, and data scientists eager to work on advanced space missions. Selected fellows will directly support upcoming earth observation, planetary exploration, and AI-driven satellite data pipelines with substantial monthly stipends and institutional backing.
About the Organization
Space Applications Centre (SAC) is ISRO's lead center responsible for conceptualizing, designing, and fabricating space-borne instruments and optical/microwave payloads. From communication transponders to cutting-edge imaging sensors on earth observation satellites, SAC bridges space technology with practical societal applications in agriculture, disaster management, weather forecasting, and defense communication. The center houses advanced payload integration labs, environmental testing setups, and dedicated computing clusters for complex satellite data modeling.
About the Job Profile
Selected researchers will participate in core R&D across diverse domains. Electronics and communication engineers will focus on RF mixed-signal ASIC design, MM-wave superconducting receivers, and cryogenic circuit testing. Earth, environmental, and atmospheric scientists will handle data from the NASA-ISRO Synthetic Aperture Radar (NISAR) mission, building algorithmic pipelines for soil moisture mapping, wetland dynamics, glacier velocity tracking, and numerical weather modeling. Computer science specialists will develop Agentic AI workflows and Large Language Models for automated satellite data retrieval.
Career Opportunities
A research fellowship at ISRO SAC offers exposure to premier national space missions. JRFs are encouraged to register for Ph.D. programs with recognized universities while utilizing SAC's advanced laboratories and datasets. Working alongside senior ISRO scientists allows researchers to publish in leading international Science Citation Indexed (SCI) journals, building credentials for future inductions into permanent Scientist/Engineer cadres or academic research tenures globally.
Preparation Tips
Because selection is based on candidate shortlisting followed by a technical interview, applicants should thoroughly review their core subject fundamentals and past academic projects. Candidates applying for JRF posts should revisit GATE/NET syllabus topics, circuit design concepts, or atmospheric physics equations. Be prepared to present past master's or doctoral thesis work, explain research methodologies, demonstrate familiarity with software tools (such as Python, MATLAB, TCAD, or GIS), and outline how your technical background fits the specific project scope.
