The Indian Space Research Organisation (ISRO) is among the most respected scientific institutions in the world and plays a crucial role in India’s space ambitions. While ISRO is widely known for its scientists and engineers designing satellites and launch vehicles, a large part of its success depends on its technical workforce. Among these roles, the position of Technical Assistant is one of the most important. This role forms the core implementation support system inside laboratories, testing facilities, and mission preparation units. Technical Assistants ensure that designs created by scientists are successfully executed in real-world applications
What Does a Technical Assistant Do
A Technical Assistant in ISRO works in different technical and engineering support functions such as assembly, fabrication, testing, inspection, maintenance, and operation of machinery or mission equipment. They function under the supervision of senior engineers or scientists and ensure that systems and components are technically sound and ready for space missions. Their work is hands-on, highly practical, and mission focused rather than purely theoretical
Functional Areas and Branches
ISRO recruits Technical Assistants in multiple engineering domains, depending on the technical requirement of individual centres. The major technical branches are
- Mechanical Engineering
- Electronics and Communication Engineering
- Electrical Engineering
- Computer Science
