About this recruitment

This recruitment drive by the Indian Space Research Organisation (ISRO) is a significant opportunity for individuals looking to contribute to India's cutting-edge space missions. ISRO, a premier space agency under the Department of Space, Government of India, is responsible for the nation's space program, including satellite design, rocket development, and space exploration. The roles on offer, ranging from Technician 'B' and Draughtsman 'B' to Technical Assistant, Scientific Assistant, Library Assistant 'A', and Cook 'A', are crucial for the day-to-day operations and long-term projects of various ISRO centres and units across the country. These positions are not merely administrative; they form the backbone of ISRO's technical and operational capabilities, ensuring that scientists and engineers have the necessary support to push the boundaries of space technology. The Technician and Draughtsman roles are vital for hands-on fabrication, assembly, and design support, while Technical and Scientific Assistants provide essential aid in research, development, and laboratory functions. Library Assistants ensure access to critical knowledge resources, and Cook 'A' positions cater to the essential needs of personnel in various facilities, often in remote or specialized locations. These roles collectively enable ISRO to achieve its ambitious goals, from launching communication satellites to planetary exploration. Typically, candidates with a strong technical aptitude, a keen interest in science and engineering, and a desire to serve in a national strategic organization apply for these posts. The prestige associated with working for ISRO, coupled with the opportunity to be part of groundbreaking scientific endeavours, makes these positions highly sought after. Aspirants should refer to the qualification table above to understand the specific educational requirements for each post and the dates table for application deadlines.

What the role actually looks like

A Technician 'B' or Draughtsman 'B' at ISRO might spend their week on the shop floor, involved in precision machining, fabrication of components, or creating detailed engineering drawings using CAD software. They work closely with engineers, translating designs into tangible parts or technical schematics. The environment is often a mix of hands-on work and technical documentation, adhering to stringent quality and safety standards. Technical and Scientific Assistants typically find themselves in laboratories, assisting in experiments, data collection, instrument calibration, and maintaining scientific equipment. Their work directly supports research and development projects, requiring meticulous attention to detail and a strong understanding of scientific principles. Library Assistants 'A' manage and organize technical literature, journals, and digital resources, ensuring that ISRO's vast knowledge base is accessible to researchers and staff. This involves cataloguing, database management, and assisting users with information retrieval. A Cook 'A' would be responsible for meal preparation and catering services, maintaining hygiene standards, and managing kitchen inventory, often in a large institutional setting. Postings can be across various ISRO centres, which are located in different parts of India, including major cities and specialized research facilities. Transfers, while not frequent, are part of a long career. Reporting hierarchies are generally structured, with clear lines of responsibility. The work environment is professional, focused, and often involves working with advanced technology and highly skilled individuals. The decisions handled by these roles, while operational, are critical for the successful execution of ISRO's projects.

Eligibility, decoded

The eligibility criteria for these ISRO positions are quite diverse, reflecting the range of roles available. For Technician 'B' and Draughtsman 'B' posts, a foundational qualification like SSLC (10th standard) coupled with an ITI (Industrial Training Institute) certificate in a relevant trade is typically required. The ITI trade must align directly with the specific technical demands of the role, such as Fitter, Electrician, Electronic Mechanic, or Draughtsman (Mechanical/Civil). Candidates must ensure their ITI certificate is from a recognized institution. For Technical Assistant and Scientific Assistant roles, a Diploma in Engineering (e.g., Mechanical, Electronics, Computer Science) or a Bachelor's degree in Science (B.Sc.) with specific subjects is usually mandated. It's crucial to check if your specific engineering discipline or science specialization is listed. Sometimes, a B.E. (Bachelor of Engineering) might be considered equivalent to a B.Tech (Bachelor of Technology), but this is not always explicitly stated and candidates should seek clarification if unsure. For Library Assistant 'A', a Bachelor's degree along with a Master's degree in Library Science or Library and Information Science is generally required. Cook 'A' positions typically require SSLC with relevant experience. There are no explicit physical or medical requirements beyond general fitness for duty, but candidates should be prepared for a medical examination as part of the selection process. Domicile requirements are generally not a factor for central government jobs like those in ISRO, meaning candidates from all states and Union Territories are eligible. Age relaxation is provided for reserved categories (SC/ST/OBC/PwBD/Ex-servicemen) as per Government of India norms; candidates should consult the official notification for specific age limits and relaxation details for their category.

Who can apply

Individuals holding qualifications from SSLC with ITI to a Master's degree, depending on the specific post, are eligible to apply. Each role has distinct educational and technical requirements, which candidates must meet as detailed in the official notification.

Selection stages — deep dive

Written Examination (CBT)

This is typically the first stage for most technical posts. It's a computer-based test (CBT) or OMR-based written exam, usually comprising multiple-choice questions. The difficulty level varies by post, testing both technical knowledge relevant to the discipline and general aptitude.

Scoring: Marks are awarded for correct answers, and there is usually negative marking for incorrect ones. The exact ratio (e.g., 1/3rd or 1/4th) for negative marking will be specified in the notification.

Tip: Focus on conceptual clarity in your technical subject. Practice time management for the general aptitude section.

Skill Test / Practical Test

Candidates shortlisted from the written exam, usually in a ratio of 1:5 or 1:10, proceed to this stage. This test assesses practical skills directly relevant to the job role. For Technicians/Draughtsmen, it might involve hands-on fabrication, drawing, or operating specific equipment. For Scientific/Technical Assistants, it could be laboratory work or software proficiency.

Scoring: This stage is typically qualifying in nature, meaning candidates must achieve a minimum score to be considered further, but marks from this stage may not be added to the final merit list.

Tip: Familiarize yourself with standard tools, equipment, and software used in your trade/discipline. Practice practical exercises relevant to the job description.

Interview

For some posts, especially at higher technical levels, an interview follows the written and skill tests. This assesses communication skills, problem-solving abilities, technical depth, and suitability for the organizational culture.

Tip: Keep all original documents organized and ready. Ensure all details match exactly with your application form.

Medical Examination

Selected candidates will undergo a medical fitness examination by an ISRO-designated medical board. This assesses general health and fitness for the demands of the role.

Scoring: This is a qualifying stage. Candidates must be declared medically fit.

Tip: Maintain a healthy lifestyle. Address any minor health concerns proactively.

Career growth & long-term earning

A career at ISRO, even in technical support roles, offers a structured and rewarding growth path. Initial promotions for Technician 'B' or Technical Assistant roles typically involve moving up through different grades within the same cadre, such as Technician 'C', 'D', and so on, or Senior Technical Assistant, and then potentially to Junior Engineer or equivalent scientific/technical officer positions. The time-to-next-grade can vary but generally involves a combination of years of service, performance evaluations, and sometimes internal departmental examinations. For instance, moving from Technician 'B' to 'C' might take around 3-5 years. ISRO encourages continuous learning, often providing opportunities for internal training, skill enhancement programs, and even sponsored higher education for deserving candidates. Lateral opportunities within ISRO are possible, allowing individuals to transition to different departments or specialized units based on their acquired skills and organizational needs. Deputation to other government departments or public sector undertakings is also an option for experienced personnel. The pension scheme for new recruits falls under the National Pension System (NPS), providing a robust retirement benefit. Beyond salary, ISRO employees enjoy a range of perks, including subsidized housing (subject to availability), comprehensive medical facilities for themselves and their families, Leave Travel Concession (LTC), and various allowances. The long-term earning potential is significant, with regular pay commission revisions and annual increments ensuring a comfortable and secure financial future, culminating in a respectable pension. The prestige of contributing to India's space program adds an intangible but immense value to the career.

Historical trends & competition

Historically, the competition for ISRO's technical and scientific support roles has always been intense, reflecting the organization's reputation and the attractive career prospects. In recent cycles, we've observed a gradual increase in the number of applicants, leading to higher cutoffs across various categories. The written examination, particularly the technical section, has become more challenging, requiring a deeper conceptual understanding rather than rote learning. For Technician and Draughtsman posts, questions on fundamental engineering principles and practical applications have gained prominence. For Scientific and Technical Assistants, the general aptitude section, including reasoning and quantitative ability, has seen increased difficulty, acting as a significant differentiator. Cutoffs for unreserved categories consistently remain high, often requiring aspirants to score well above average. Reserved categories also experience stiff competition, with their cutoffs trending upwards, though still lower than the general category. This trend implies that a fresh aspirant needs to focus not just on their core technical subject but also on strengthening their general awareness and problem-solving skills. The skill test, while qualifying, has also become more rigorous, demanding genuine hands-on proficiency. Candidates who historically performed well were those who balanced theoretical knowledge with practical application and maintained a consistent study schedule over several months. The takeaway is clear: success requires comprehensive preparation, not just a last-minute cramming effort.
