Work / Can I find a job in Poland that requires speaking in English? [82]

I am 18 and going to Poland in September to complete a Polish course as my Polish has become very weak. (Born in England). I was wondering if I was to stay in Poland longer than a month would it be possible for me to find a job that requires speaking in English? Its likely that even after completing the course my Polish wont be strong enough to work in any customer facing jobs.

Thank you,
Claudia
