Before you apply for a job, make sure that your education is recognised in Poland. This process is called diploma nostrification and means that foreign diplomas are recognised on a par with those issued by Polish universities. 

You can easily check the recognition of your diploma using the application KWALIFIKATOR:  https://nawa.gov.pl/en/recognition/system-kwalifikator  

You can find more information on the website of the Polish National Agency for Academic Exchange: https://nawa.gov.pl/en/recognition/how-to-obtain-a-recognition-statement
