Hello @Salah Nour , Thank you for your question on our platform. Indeed it is not easy to apply for a job outside of Germany, especially when you do not know the language well. Well done for already achieving A1, that’s a great start. 
 . The level of German required depends on the type of job you are seeking. You will have to check with the company what is required. Some major job-search platforms out there are, for instance, www.monster.de, www.stepstone.de, www.jobbörse.de, www.adzuna.de and the job search engine of Make-it-in-Germany.de
.
You can read more important tips on the job hunt and applications for jobs in Germany: https://handbookgermany.de/en/jobsearch-and-application . There is also a job seeking visa, which allows you to search for a job in Germany for 6 months, you will not need to show any level of German knowledge if you have a university degree that is recognised in Germany 
if you have vocational training then you will need to proof a level of B1, again this vocational training should be recognised. 
You can find all the regulations for this visa here: https://handbookgermany.de/en/visa-jobseekers Maybe this type of visa could be an option for you. 
Please let me know if you have further questions. 
Best wishes Yara

You are very welcome @Salah Nour . Your age is not a problem, you can still apply for most visas. Such as the visa for job search. There are some visas where there is an age limit, such as the the visa to search for a vocational training, the age limit here is 25 years old. 

 . Please note that with a job seeker visa you cannot take your family with you. You can apply for the blue card or skilled workers visa together with you family. 

You can take a look at our information page on immigration to Germany. We have listed many different types of visas and the application requirements. https://handbookgermany.de/en/immigration Best wishes
