We use Bitpusher as our vendor for sysadmin/ops at Posterous. They're a great group of people to work with, and they get to see a lot of different environments since they specifically specialize in working with startup ops.

On the engineering/development side we're hiring for dev-ops / infrastructure engineers who love to scale.
