All the best.

Try to be really an expert in one of the programming languages. Work for a company for some time to understand how a process driven organization works. And then develop your own product and get started with your start up.
If you want a job only then make your profile strong. Work for live projects, participate in competitions, develop your communication skills and confidence. It's always a good idea to first work for a startup. In the initial years, don't run behind money. Run behind gaining knowledge and skills. Once you have them job providers will be in search of you rather than you searching for a job.

Yes, you are eligible to apply for SSC junior engineer after B.Tech ECE. Even the Diploma students are eligible for the same.
