This October/November was a total s*%t show trying to find accommodation. Its good you have some couches to crash on. Finding a job was certainly easier than finding accommodation but in November it will be pretty competitive for jobs also as a lot of people will be arriving in town.
I wouldn't worry too much about finding a job, there always seems to be some advertised in the local paper. Check out here for some tips: http://www.whistlerseasonaires.com/2013/06/ultimate-whistler-jobs-guide/
Jobs that will allow you most time on the mountain would be Kitchen Steward, Night Houseman, Night Cleaner, Night Audit .... anything that starts with night ;)
