In some countries like India, government institutions have positions for their research projects, something you can opt for as long as you have a valid qualification although the interviews can be hard to pass. The first option in such countries is JRF which is manageable as getting the GATE score is a bit challenging for starters.
There is this option of being an independent researcher and through this, you can have projects where you do the research and publish the results in known journals. In such scenarios, it is good that you find an entity to finance you to cater for your expenses. Independent researchers mostly have a Physical Degree and another clique has experience in research on top of the degree.
Researchers take up projects, make it a subject of research and systematically offer findings making them develop a system. After being through with the research, you should patent it and can sell the patent to big companies, and that is how you shall make your income. The research publications are another source of income, and to hit that level, you should be patient and advance degrees.
You can get into research again by taking a research proposal to a big company that supports research like ISRO or DRDO. These organizations will look into your proposal and analyze it, and if it fits the standards which they want, they will fund your research from scratch to the end. The education qualification for people who do these is the physical degree which makes it hard for people to get researches funded. Getting a job in research immediately after getting your undergraduate degree is rare and most who pursue this go for post graduations.
There is a wide range of research in any field of engineering, your choice relies on what interests you. If you know what you want for yourself from the early stages, it is advantageous because you will spend your time planning on the best way to approach your goals. The clarity of opting for research is good because you can easily choose between money and self-satisfaction. In research, money is not usually the top priority and being gratified by doing what interests you will drive you to the end. The point where you can patent and sell to the big companies and sell your publications.
Entering into research so that you can have a good curriculum-vitae is not advisable because research has its challenges that will need you to be objective. Objectivity helps in making sober career decisions by making sure that what you want is possible to achieve. Do your background research about the research you want to start so that you can plan extensively on how to go about it. Ensure that as you learn about the area of research, you also gain other skills for good research work and convince investors to put money into your work because of your abilities. In India, students prefer getting jobs rather than going to the research field, this presents a lot of changes in this field as there are only a few students available for that choice.
