Engineering is such a broad discipline. There is already a number of specialties in engineering, and these specialties may also have sub-specialties. People who enjoy having different things to do would be happy to work in engineering. If you are interested, it may be overwhelming to check which is the best fit for you. If you like airplanes and rockets, you might want to check for a Propulsion Engineer position.
Propulsion Engineers oversee the design of the propulsion components. These components include jet engines, rocket motors, and compression systems. They oversee the workers who will build these components. They would then have to make sure that these components are working well. They are often found in the aerospace industry, given that their specialty is centered on propulsion.
If you have a special interest in building things and making the world safer, you can be a propulsion engineer. Of course, you need to undergo engineering studies, so you should also be inclined to undergo training.
