ISRO Telemetry Tracking and Command Network (ISTRAC) Technician-B, Draughtsman-B, Technical Assistant, Scientific Assistant, Library Assistant, Cook-A Recruitment 2026

The ISRO Telemetry Tracking and Command Network (ISTRAC), based in Bengaluru, is an essential arm of the Indian Space Research Organisation (ISRO). Established to support India's satellite and launch vehicle programs, ISTRAC plays a pivotal role in operations including vehicle health monitoring, telemetry data acquisition, and control during satellite launches. Over the years, ISTRAC has evolved into a significant hub housing several advanced technologies for tracking and controlling space missions, contributing to India's expanding capabilities in space.

Candidates selected for positions such as Technician-B (Electronics Mechanic and Carpenter) and Draughtsman-B (Civil and Mechanical) are involved in hands-on technical work crucial for supporting ISRO's missions. Their day-to-day functions may include assembling electronic devices, performing maintenance tasks, working with blueprints, or preparing technical drawings, depending on their specialization. Technical Assistants (Electronics and Mechanical) focus on applying their engineering knowledge to resolve technical challenges and assist in various projects. Work typically takes place onsite at ISRO facilities, requiring candidates to collaborate closely with engineers and other technical staff, often in a uniformed environment.

Selected candidates will utilize advanced tools and technologies relevant to their fields, such as CAD software for Draughtsmen or electronic testing equipment for Technicians. These roles involve a mix of fieldwork and desk duties, with opportunities to engage directly with cutting-edge projects in India's space program.

The pay scale for these positions is structured under the Pay Levels outlined in the government pay matrix. For instance, Technician-B posts fall under Pay Level 3, which translates to an approximate basic salary of ₹21,700, along with allowances such as HRA (House Rent Allowance) which can vary based on the city's classification (up to 24% for metropolitan areas). After deductions, the in-hand salary is estimated to be around ₹26,000 to ₹30,000.

As for career growth, individuals can expect promotions within 5-10 years, potentially advancing to Senior Technician or similar roles after demonstrating consistent performance and acquiring further skills. Those in Technical Assistant roles, positioned at Pay Level 7, start with a higher basic pay of around ₹35,400, providing a significant jump in responsibility and scope for career development.

Working at ISTRAC comes with multiple benefits. Medical facilities through CGHS or state schemes, leave travel concessions (LTC) for travel within India, and subsidized housing are significant perks. Employees also benefit from comprehensive insurance coverage, the New Pension Scheme (NPS), and opportunities for study leave to pursue further education and skills development. Additionally, a canteen service at nominal rates is available, promoting a comfortable workplace atmosphere.

The selection process typically involves a two-tiered approach. The first stage comprises a Computer-Based Test (CBT) that assesses candidates on technical knowledge and reasoning abilities, with subjects such as General Knowledge, Mathematics, and specific technical topics related to the applied role. Expect around 100 questions with no negative marking, making it crucial to attempt all questions.

Preparation strategies should include familiarizing oneself with the ISRO exam pattern. Recommended resources include NCERT books for science subjects, reference books specific to engineering for Technical roles, and subjects like Mathematics for Draughtsman candidates. Practice online mock tests and previous year question papers to gauge preparation levels effectively.

This recruitment drive is ideal for candidates with technical degrees or diplomas and those passionate about contributing to India’s space missions. The roles combine both technical expertise and innovative thinking, making it suitable for individuals who are excited by challenges and teamwork. Conversely, those who prefer purely theoretical work without hands-on engagement may find these posts less appealing. Compared to similar roles at other governmental organizations, ISTRAC provides unique experiences within the space sector, amplifying its significance.
