ISRO ISTRAC Technical Assistant Job Profile 2026: Roles and Responsibilities

The Technical Assistant post (Electronics and Mechanical disciplines) is one of the most sought-after roles in this ISRO ISTRAC recruitment because of its Pay Level 7 salary structure and strong technical exposure. Based on the nature of ISTRAC’s core functions, Technical Assistants in Electronics typically support satellite tracking systems, telemetry reception, ground station equipment maintenance, and signal processing operations. Those posted under Mechanical discipline generally assist with maintenance of antenna systems, mechanical structures at ground stations, and equipment servicing.

Postings for this role are spread across multiple ISTRAC centres including Bengaluru, Thiruvananthapuram, SDSC SHAR (Andhra Pradesh), Sri Vijayapuram (Andaman & Nicobar Islands), and even NESAC Umiam — meaning selected candidates should be prepared for an all-India posting liability and round-the-clock shift work, since ground station operations run 24×7 to track satellites and launch vehicles in real time.

ISRO ISTRAC Scientific Assistant Job Profile 2026-  Roles and Responsibilities

Scientific Assistants (Computer Science and Mathematics streams) generally support data processing, software-related ground segment operations, computational analysis for tracking data, and technical documentation. Given ISTRAC’s emphasis on Space Science Data Centres and precise timing facilities, Computer Science Scientific Assistants are likely to be involved in data centre operations, network monitoring, and software support for telemetry systems, while Mathematics stream assistants typically contribute to orbital computations, data analysis, and statistical processing that underpins satellite tracking accuracy.

ISRO ISTRAC Technician-B and Draughtsman-B Job Profile 2026

Technician-B posts (Electronics Mechanic and Carpenter trades) involve hands-on technical support — electronics equipment installation, wiring, repair, and maintenance work for ITI-qualified candidates, while the Carpenter trade Technician supports facility maintenance and infrastructure work.

Draughtsman-B (Civil and Mechanical) roles involve preparing technical drawings, engineering layouts, and design documentation to support ISTRAC’s construction, infrastructure development, and mechanical design requirements at various ground stations.

ISRO ISTRAC Library Assistant-A and Cook-A Job Profiles 2026

The Library Assistant-A post supports ISTRAC’s technical library and documentation centre, managing scientific literature, journals, and reference resources for ISRO’s scientific and engineering staff — an essential but often overlooked support function in a research-heavy organisation. The Cook-A post, meanwhile, supports ISTRAC’s canteen and catering services, requiring five years of prior professional cooking experience at a recognised hotel or canteen (experience certificates from individuals are not accepted).

Selection Process for ISRO ISTRAC 2026 Posts

All posts (except Cook-A) follow a Written Test/CBT of 80 MCQs in 1.5 hours (+1 mark for correct, -0.33 for wrong answer), followed by a qualifying Skill Test conducted for 100 marks. Cook-A candidates take a 60-MCQ written test followed by a Skill Test where 60/100 marks are required to qualify, with no relaxation for any category.

Pass marks for Unreserved candidates are 32/80 in the written test and 50/100 in the skill test; reserved category candidates need 24/80 and 40/100 respectively. Shortlisting for skill test happens in a 1:5 ratio with a minimum of 10 candidates. Final selection is based purely on written test/CBT marks among those who clear the skill test.

Career Growth in ISRO ISTRAC 2026 – Long-Term Prospects

One of the biggest draws of ISRO ISTRAC 2-026 job profile is career growth built on a Merit Promotion Scheme rather than dependency on vacancy availability — meaning scientific and technical staff are reviewed for promotion to the next grade after a prescribed residency period, purely on merit, without needing an open vacancy. This is a major advantage over many other government jobs where promotions stall due to lack of vacant posts. Administrative staff promotions, however, remain vacancy-dependent.

Beyond salary, ISRO offers employees free transport or transport allowance, limited housing facility or HRA, computer purchase advances, home construction loans, Leave Travel Concession, Group Insurance, subsidised canteen facilities, and an attractive medical scheme for employees and dependents. Employees are enrolled under the National Pension System/Unified Pension Scheme.

For candidates aiming at long-term careers in India’s space sector, starting as a Technician, Draughtsman, Technical Assistant, or Scientific Assistant at ISTRAC can be a stepping stone toward senior scientific and engineering roles within ISRO over the years, backed by continuous skill development and exposure to cutting-edge satellite tracking technology.

Important Guidelines for ISRO ISTRAC 2026 Applicants
