Work / Work Permit and Requirement (not authorized to work in Poland) [12]

Hi! I have PhD and have a job offer in Poland. I am a non-EU citizen but hold a permanent residence of another EU country. I can enter Poland and stay up to 3 months as a tourist, but apparently I need residence and work permit.

Would you please tell me how much I time I need to receive residence and work permit? and what are the sequences to apply? Do I need to apply for a residence card first and then work or? I also appreciate you kindly tell me since when I can start the work, is it after application for work permit or I must wait to receive it! Thanks a lot!
