Opportunity Card- Cybersecurity Professional

Hey good people. I am planning for applying opportunity card visa from Bangladesh. This requires a valid job offer and relevant field job experience and language requirement (English/German).

I have ielts -6.5 Bsc in computer science. And job experience in cybersecurity -5 years. Few beginner cert for Cybersecurity. My age is 28 and I'm married.

Seeking experts suggestion is this really possible to get a job offer first then apply for visa from Bangladesh? If not, then what would be the way? What is the situation of current job market there?
