Just go to the webpage of game developers or publishers like EA or Ubisoft. Lots have job sections and if they are looking for testers, then you will find it there. Like flat line, I've been working in that industry for years (not as a tester, but IT).
The testers usually are not paid very well, except for the ones with ages of experience. Their working hours can be extreme, especially in crunch time (when the game MUST be finished soon) and if you have fun to do the same things (which will probably crash the game) over and over again is for you to decide. But, for some, it really is a fantastic job nontheless. I know some of them
