The Indian Space Research Organisation (ISRO) has opened applications for 746 positions as the Department of Space faces its highest staff vacancy rate in 25 years.
The recruitment drive includes 336 regular positions and 410 apprenticeship opportunities, covering scientists, engineers, administrative staff and trainees. The move comes after the Department of Space reported 5,632 unfilled posts, equivalent to nearly 30% of its sanctioned workforce.
The hiring exercise is among ISRO’s largest in recent years and comes at a critical time as India expands its space programme while simultaneously opening the sector to private companies.
ISRO opens 746 positions
The latest recruitment drive is spread across three notifications issued between July 27 and July 29.
Of the 746 openings:
| Category | Vacancies |
|---|---|
| Regular positions | 336 |
| Apprenticeships | 410 |
| Total | 746 |
Of the regular vacancies, 43 are backlog positions, while the remaining openings are intended to strengthen the organisation’s current workforce.

The recruitment covers several major ISRO centres across India.
Department of Space has 5,632 vacant posts
The scale of the recruitment becomes clearer when compared with the Department of Space’s overall staffing position.
Earlier this year, the government told Parliament that the Department of Space had 5,632 vacant positions, representing nearly 30% of its sanctioned workforce. The vacancy rate was described as the highest in at least 25 years.

Even if all 746 newly advertised positions are filled, thousands of vacancies would remain.
This means the latest recruitment drive is an important step but will not completely solve ISRO’s staffing shortage.
92 Scientist/Engineer posts announced
Among the regular vacancies, ISRO has opened 92 Scientist/Engineer ‘SC’ positions under Level 10 of the pay matrix.
The largest number of technical positions is in electronics engineering.
| Engineering discipline | Posts |
|---|---|
| Electronics | 34 |
| Mechanical | 26 |
| Computer Science | 13 |
| Civil | 10 |
| Electrical | 4 |

The distribution reflects the broad engineering requirements involved in spacecraft, launch vehicles, ground infrastructure and other space systems.
Administrative recruitment also underway
ISRO is not limiting the hiring exercise to scientists and engineers.
The ISRO Centralised Recruitment Board (ICRB) is recruiting 244 Level-4 administrative employees.
These include:
- 113 Assistants
- 81 Junior Personal Assistants
- 22 Upper Division Clerks
- 10 Stenographers
- Other administrative positions

This is significant because ISRO’s workforce requirements extend well beyond scientists and engineers.
Large space programmes require finance, procurement, administration, documentation, logistics and other support functions.
410 apprenticeship positions at URSC
The recruitment drive also includes 410 apprenticeship positions at the UR Rao Satellite Centre (URSC) in Bengaluru for the 2026-27 training cycle.
Apprenticeships provide ISRO with a way to build a future talent pipeline while giving young technical graduates and trainees exposure to India’s space programme.

This is particularly important as India’s space industry expands beyond government agencies into private launch companies, satellite manufacturers and space-tech startups.
Which ISRO centres will get new employees?
Successful candidates will be posted across several major ISRO and Department of Space facilities.
These include:
| Centre | Location |
|---|---|
| UR Rao Satellite Centre (URSC) | Bengaluru |
| Human Space Flight Centre (HSFC) | Bengaluru |
| ISRO Headquarters | Bengaluru |
| Vikram Sarabhai Space Centre (VSSC) | Thiruvananthapuram |
| Satish Dhawan Space Centre | Sriharikota |
| Space Applications Centre (SAC) | Ahmedabad |
| National Remote Sensing Centre (NRSC) | Hyderabad |
| Liquid Propulsion Systems Centre (LPSC) | Valiamala |
| ISTRAC | Bengaluru |
The geographical spread shows that the staffing shortage affects multiple parts of ISRO rather than being concentrated at one centre.
Staffing pressure comes as India’s space programme expands
The recruitment drive comes at a particularly important moment for India’s space programme.
ISRO is working on multiple ambitious programmes, including:
- Gaganyaan human-spaceflight missions
- Chandrayaan and planetary exploration
- Earth-observation satellites
- Communication satellites
- New launch vehicles
- Reusable launch technologies
- Space docking and rendezvous
- Future space-station capabilities
At the same time, India’s private space industry is expanding rapidly.

The staffing gap therefore has implications for the pace at which India can execute these programmes.
Why the 25-year vacancy high matters
A nearly 30% vacancy rate means ISRO and the Department of Space are operating with a substantially smaller workforce than their sanctioned capacity.
That can put pressure on existing employees.

Potential impact on
project execution
The issue is particularly important for a highly specialised organisation because replacing an experienced space engineer is not as simple as filling an ordinary administrative vacancy.
Spacecraft and launch-vehicle development often require years of specialised experience.
Experience is particularly valuable in space programmes
Space engineering depends heavily on institutional knowledge.
Engineers and scientists develop expertise in areas such as:
- Propulsion
- Avionics
- Guidance and navigation
- Satellite systems
- Thermal engineering
- Materials
- Communications
- Mission operations
- Launch systems
When experienced personnel leave, replacing them can take years.

This makes workforce planning particularly important for ISRO as mission complexity increases.
The private sector is also competing for talent
India’s space sector has changed significantly in recent years.
Companies such as launch startups, satellite manufacturers and space-tech firms are attracting engineers and scientists who previously had fewer career options outside government organisations.
This creates a new talent environment.

The expansion of private-sector opportunities is positive for the overall space industry, but it also means ISRO must compete more actively for specialised talent.
India’s private space boom changes the workforce equation
India has been encouraging private participation in space activities through reforms and the creation of IN-SPACe.
Private companies are increasingly working on:
- Launch vehicles
- Satellite platforms
- Propulsion systems
- Earth observation
- Space electronics
- In-orbit servicing
- Ground systems
That means the demand for skilled aerospace and engineering professionals is likely to increase.

The 746-job recruitment drive therefore comes at a time when the entire Indian space ecosystem needs more skilled workers.
Recruitment alone may not be enough
The latest hiring exercise will help reduce the vacancy gap, but it is unlikely to eliminate the problem.
With 5,632 vacancies previously reported, filling 746 positions would leave a substantial number of posts vacant.

Large remaining gap
Some of the 746 positions are apprenticeships rather than permanent employees, so the immediate reduction in the overall vacancy count will be smaller than the headline figure might suggest.
Why apprenticeships are strategically important
The 410 apprenticeship positions should be viewed as a longer-term workforce investment.
Space organisations require highly specialised technical skills, and building those skills takes time.
Apprenticeships can create an early pipeline of candidates familiar with ISRO’s engineering environment.

Even when apprentices do not ultimately join ISRO, they can take those skills into India’s broader aerospace and space-tech ecosystem.
Electronics is the biggest technical hiring area
Electronics engineers account for the largest group among the 92 Scientist/Engineer vacancies, with 34 positions.
That is unsurprising given the importance of electronics in modern spacecraft.
A satellite can contain complex systems for:
- Communication
- Navigation
- Power management
- Sensors
- Data processing
- Control systems
- Telemetry
- Command systems

The 34 electronics positions therefore highlight the continuing importance of electronics and embedded systems in India’s space programme.
Computer science also features in recruitment
The recruitment includes 13 Computer Science positions.
This reflects the growing importance of software in space missions.
Modern spacecraft increasingly depend on:
- Embedded software
- Mission-control systems
- Simulation
- Data processing
- Artificial intelligence
- Cybersecurity
- Autonomous navigation

This makes technical recruitment increasingly important.
Human spaceflight adds another layer of demand
The Human Space Flight Centre (HSFC) in Bengaluru is among the centres receiving candidates under the recruitment drive.
Human spaceflight requires expertise beyond conventional satellite missions.
It involves:
- Life-support systems
- Crew safety
- Human-rated launch vehicles
- Environmental control
- Space medicine
- Mission operations
- Crew training
- Recovery systems

A shortage of skilled personnel can therefore become a strategic constraint.
ISRO recruitment comes amid major space ambitions
India has set increasingly ambitious goals for its space programme.
These include developing stronger human-spaceflight capabilities, expanding satellite infrastructure, improving launch capacity and eventually supporting a larger presence in low-Earth orbit.
At the same time, India is seeking to increase its share of the global space economy.
Achieving those goals will require both capital and people.

The 746 openings address one part of that equation.
What the recruitment means for India’s space economy
The hiring drive has implications beyond ISRO.
As more scientists and engineers are trained in India’s space ecosystem, they can potentially contribute to private companies as well.
This could create a positive feedback loop:
ISRO
↓
Trains engineers
↓
Builds expertise
↓
Space ecosystem expands
↓
Private companies grow
↓

↓
Larger talent pool
India’s space ambitions therefore depend on building a workforce large enough to support both government and commercial activity.
The challenge is retaining experienced employees
Hiring new employees addresses one side of the problem.
The other is retaining experienced staff.
A large organisation can recruit hundreds of young engineers but still lose critical institutional knowledge if senior specialists leave.

For ISRO, balancing these four areas will be increasingly important as private-sector opportunities expand.
The 746 jobs are only part of the solution
The latest recruitment should therefore be viewed as a capacity-building measure rather than a complete solution to the staffing crisis.
The Department of Space still has thousands of vacant posts.
The immediate priorities are likely to include:
- Filling existing vacancies
- Recruiting specialised engineers
- Building apprenticeship pipelines
- Retaining experienced personnel
- Developing new technical skills
- Expanding workforce capacity alongside new programmes

What happens next?
The current recruitment drive will bring in new scientists, engineers, administrative personnel and apprentices across ISRO’s network.
The bigger question will be whether future recruitment rounds can gradually reduce the 5,632-post vacancy backlog.
As India’s space programme expands, workforce requirements are likely to remain high.

Conclusion
ISRO’s decision to open 746 positions comes at a crucial point for India’s space programme.
The recruitment drive is significant on its own, but the number that matters most is the 5,632 vacancies already reported across the Department of Space.
That figure means nearly three out of every 10 sanctioned positions were vacant, putting the organisation’s staffing rate at a 25-year low.
The latest hiring exercise attempts to address the problem from several directions.
ISRO is recruiting 92 scientists and engineers, including specialists in electronics, mechanical engineering, computer science, civil engineering and electrical engineering.
It is also filling 244 administrative positions, ensuring that the organisation has the support staff required to operate its growing network of research centres and programmes.
And perhaps most importantly for the longer term, 410 apprenticeships are being added at the UR Rao Satellite Centre in Bengaluru.
This combination of immediate recruitment and talent development is important because India’s space programme is becoming considerably more ambitious.
ISRO is simultaneously working on human spaceflight, advanced launch systems, satellite programmes, autonomous spacecraft operations and future space infrastructure.
At the same time, India’s private space industry is growing rapidly.
Launch startups, satellite manufacturers and other space-tech companies are creating new demand for engineers with expertise in propulsion, avionics, electronics, software, robotics and satellite systems.
That creates both an opportunity and a challenge for ISRO.
The opportunity is a much larger Indian space ecosystem with more jobs, more companies and greater technological capability.
The challenge is that ISRO must now operate in a labour market where highly skilled engineers have more career options than they did in the past.
That makes retention of experienced employees just as important as recruiting new ones.
For a space organisation, experience has enormous value.
A senior engineer who has worked on multiple satellite or launch-vehicle programmes carries knowledge that cannot simply be replaced by hiring a new graduate.
Therefore, the 746 openings should be seen as the beginning of a broader workforce-building effort rather than the final solution.
The immediate objective is to fill critical positions.
The longer-term objective should be to create a sustainable pipeline:
Recruit → Train → Retain → Develop.
If India wants to expand its share of the global space economy, it will need not only rockets, satellites and launch infrastructure, but also the people capable of designing, operating and improving them.
The current recruitment drive is therefore about more than government jobs.
It is about building the human capital needed for India’s next phase of space development.
With thousands of vacancies still remaining, the pace and scale of future recruitment will be an important factor in determining how effectively ISRO can execute its increasingly ambitious mission roadmap.
