The current process for recruiting online community managers is crazy.
Forget the job description.
Instead, invite interested people to create a fan group for your product/brand. Give them a month or two. Then hire those who built the best fan groups.
You get a great community manager and a great community.
Likewise, if you're looking for a community management job stop applying and start building. It's much harder to turn an applicant down if they have already built a community for you.
