Jobs in AML that sponsor a visa?

Visa sponsorship means the sponsor would take on full financial responsibility for everything you do in Germany, incl. Living expenses, health and legal fees incl deportation costs etc. No sane company or person would agree to do that for you (except maybe very good friends and family members). And neither do you need it!
What you need is a job offer and some help with the formalities of applying for a work permit. E.g. the company has to give you some extended documentation, job description, etc. and might need to justify why they want to hire a foreigner (and not an EU citizen with the same skills). This will still get you thrown out of many shortlists, but not all - especially if you focus on jobs for which you have niche skills that no or few Europeans have. It also helps a lot if you speak German, of course.

Thank you very much for your insights! I am currently looking into options, I do not want to give up on my goal, but sometimes is really difficult as I want to prove potential employers that all I need is the job offer and I will be glad process the work permit here in my country.

You have to, in any case, apply for the work visa by yourself at the German embassy in your country (the process can take a few months). The employer only needs to support the paperwork.
For now, all you need to do is convincing an employer that you are the best person for the job - better than any European. They then must convince the visa authorities of the same.
Good luck!
