im a fibre optic engineer which is sort of telecomms
Try one of the telecom or computer equipment manufactures that have their divisions in Poland (like Alcatel-Lucent, Nokia-Siemens, Intel etc.). Their staff usually speaks English well so you at least shoudn't have problems communicating in work ;-) But be prepared that they pay less than e.g. in US (this is why they moved their business here), and if you really want to keep friendly and close relationship with co-workers you should learn Polish quickly, because not many people would like speak only English when drinking beer after work ;-)
