You need a job offer and your employer needs to file for and pay $1k for a LMIA. The LMIA shows that no Canadian or PR could be hired. Then with LMIA, you apply for a closed work permit showing that only you are experienced enough for the job. Few, if any, employers will respond unless your knowledge is so specialized that no one in Canada can do the job.
Sorry to rain on your parade, but the chances of getting recruited is minuscule if you are applying from outside Canada without any type of work authorization.
