Hey,

Aerospace Engineers design spacecraft, aircraft, missiles and weapons systems. In addition, they are also responsible for assembling, maintaining and ensuring they function properly at all times. Some specialise in other important equipment such as air guidance systems, guidance control systems, propulsions, etc.

Duties of an Aerospace Engineer include:

Developing new technologies for use in spacecraft, aviation and defense systemsDesigning, assembling and testing of aircraft and aerospace productsExamine damage or malfunction in an equipment to find our possible reason and offer solutionAssessing cost and feasibility of new projects proposed to be undertakenDetermining quality standard acceptance criteria for design methods, quality standards, sustainment after delivery, and completion datesEvaluating that the project or the product meets engineering principles, safety norms, customer requirements and environmental challengesManufacturing aircraft and individual components in coordination with the design team.Aerospace Engineers take on specialised areas of functioning such as software engineering, structural engineering, mechanical engineering, electrical and electronic engineering, for automation and guidance purposes, aerodynamics or propulsion systems.

Aerospace Engineers specialise in two types of Engineering: Aeronautical and Astronomical.

Aeronautical Engineer: An Aeronautical Engineer works on aircrafts and its components.

Astronomical Engineer: An Astronomical Engineer works specifically on spacecraft and related technologies.

Aerospace Engineering is an ever evolving field, adopting new technology for further development in production and functioning of aircrafts and spacecrafts. Earlier the space was dominated by government organisations, but with the entry of many private players, opportunities in this industry are growing more and more. Here are a few organisations that hire Aerospace Engineers in various capacities:

Indian Space Research Organisations (ISRO)
Hindustan Aeronautical Limited (HAL)
National Aerospace Laboratories (NAL)
Defence Research And Development Organisation (DRDO)

Private companies that hire Aerospace Engineers for their aircraft related projects are: Airbus, Boeing, Goodrich, GE.

Hope this helps.
