Hi!

Yes, you can become a Software Engineer after Electronics and Communication Engineering if you have a sound knowledge in Programming Languages and Coding. If you know Java, C, C++ and Python as most of the IT Companies prefer these, then you are good to go! If your college has placements from IT companies give it a try, have a good score. There are various IT Companies like Infosys, CTS, TCS, Accenture, Wipro, etc,.

You can also try Nokia, Siemens, where VLSI Design in making the Integrated Circuit will help you. So you can become a Software Engineer in an Electronic Field!

Hope this is helpful!

All the best!
