1. Python

Python is a top choice for a job at ISRO because it’s a handy programming language. It’s easy to understand, and lots of people like using it. Python is great for doing things like looking at satellite data, making pretend space missions, and making machines do tasks by themselves in space.

  • Python Can Do a Lot: Python is handy at ISRO because it can do many different things. It’s good at dealing with big data sets from satellites, creating simulations for space missions, and making machines do things in space.
  • Lots of Job Chances: If you know Python, you can apply for many jobs at ISRO. You could work on software for controlling satellites or look at data for space missions. 

2. C/C++

Regarding space technology, C and C++ remain the bedrock of programming languages. ISRO relies heavily on these languages to develop mission-critical systems, satellite software, and embedded systems. If you aspire to work in the heart of India’s space program, a solid understanding of C and C++ is necessary.

  • Legacy Systems and Compatibility: ISRO often works with legacy systems and hardware. C and C++ are ideal for maintaining and enhancing these older systems while ensuring backward compatibility. If you aim to work on maintaining and upgrading existing satellite software, a strong command of C/C++ is a valuable asset.
  • Learning Opportunities: While C and C++ may have steeper learning curves compared to some other languages, the investment in mastering them pays off significantly. The demand for C/C++ experts in space technology is consistent, and ISRO frequently seeks professionals with these skills.

3. Java

Java, known for its platform independence and extensive libraries, plays a crucial role in the Indian Space Research Organization (ISRO). Although more dominant than Python or C/C++, Java has its niche in satellite control systems, software development, and telemetry. Understanding Java can be a valuable asset for securing a job at ISRO.

  • Safety-Critical Applications: Java is well-suited for safety-critical applications, such as those in space technology. Its memory management and exception-handling mechanisms provide robustness and reliability. This is crucial for ensuring the smooth operation of satellite systems, where errors can have severe consequences.
  • Software Development: ISRO often requires software developers who can work on mission-critical applications. Java’s extensive standard library and vast ecosystem of third-party make it a powerful tool for software development. Java proficiency is valuable whether developing control software for satellites or ground control systems.

4. Fortran

ISRO relies on Fortran primarily for tasks involving complex mathematical computations and simulations, which are integral to space research. Furthermore, Fortran code can be efficiently optimized for performance, a crucial aspect of space missions where every ounce of computational efficiency counts.

To secure a job at ISRO, mastering Fortran can be a wise investment. Start with the basics, learning to declare variables, write loops, and manipulate arrays. Gradually progress to advanced topics such as parallel processing and interfacing with other languages like C and Python. 


In the context of ISRO, MATLAB plays a crucial role in satellite image analysis, remote sensing, and mission control. Moreover, MATLAB’s integration capabilities with other languages and software like Simulink and Python enhance its utility in interdisciplinary projects within ISRO.

To stand out as a potential candidate for ISRO, it’s essential to become proficient in MATLAB to familiarize yourself with the basic syntax, data manipulation, and plotting techniques. Building a solid foundation in MATLAB will open doors to exciting career opportunities at ISRO.

6. Assembly Language

Assembly language, often called ASM, is a fundamental programming language that bridges the gap between human-readable code and the binary instructions that computers understand. It’s the language that empowers programmers to communicate directly with a computer’s hardware, making it indispensable for space technology applications.

ISRO relies heavily on software to control spacecraft and perform critical tasks in the space industry. Assembly language is crucial because it allows programmers to communicate directly with a computer’s hardware. This is essential for ensuring software works efficiently and effectively in space technology applications.

7. SQL (Structured Query Language)

Structured Query Language is the universal language for managing and manipulating databases. Proficiency in SQL opens doors to fulfilling careers in database management and data analysis within ISRO, making it a must-learn language.

 ISRO relies heavily on data-driven decision-making for its space missions. SQL is the cornerstone of database management systems that store, retrieve, and analyze mission-critical data. SQL queries enable ISRO professionals to extract meaningful insights from massive datasets, from tracking satellite orbits to monitoring equipment health. 


Mastering programming languages like Assembly Language and SQL is crucial for aspiring candidates seeking a job at ISRO. These languages empower professionals to optimize spacecraft software and manage mission-critical data efficiently. By acquiring proficiency in these languages, you can enhance your prospects of securing a rewarding career in space technology at ISRO.
