Computer Engineer

A software engineer is a person who applies the principles of software engineering to the design, development, maintenance, testing, and evaluation of the software and systems that make computers or anything containing software work.
You have following options to become a software engineer:
(a) B.Tech CS/ IT
(b) BCA-MCA,
(c) B.Sc-M.Sc CS/IT.
(d) Diploma in Computer Science from a polytechnics
(e) Computer courses
There is only subtle difference between CSE, IT and SE. IT Industry accepts all three to start career as Software Developer. Majority of institutes offer o work as software engineer. B.Tech CSE and it the most accepted degree in IT industry to work as a Software engineer. Let me explain you difference between CS, IT and SE.
Computer science the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems. B.Tech IT degree has a major focus on computers and technology, it differs from a Computer Science degree in that students are also expected to study management and information science, and there are reduced requirements for mathematics and theory of computation. Software Engineering (SE) deals with building and maintaining software systems. It is more applied than Computer Science, placing greater emphasis on the entire software development process, from idea to final product. It is also more disciplined than Computer Science, applying more systematic practices to help ensure that products are reliable and safe.

There are multiple job opportunities available in the field of IT. As per NASSCOM Indian IT Industry revenues grew by 13% in FY2015 and it added 2,30,000 employees in FY15. NASSCOM has forecasted that IT industry exports will grow by 12-14% and domestic market by 15-17% in FY2016 ( Actual data is yet to be released. Indias IT-BPM industry is projected to grow ~8% in FY2017 to USD 154 billion. In light of the very disruptive emerging technologies, the industry is re-imagining itself to become the Digital Solutions Partner for the world. CSE & IT grads from top engineering colleges have excellent career opportunities.
