Landing a job abroad usually means that you would require a work visa for that country. This means that you will have to find a company that is willing to sponsor you. Another option is to pursue your higher education abroad, post which you will be eligible for a post-study work permit and allowed an average staback of 2-3 years depending on the country. It is advised that you pursue an MS in Computer Science or a postgraduate diploma in a related field so as to maximise your chances. All the best!
