What Rinzwind says is true. Though I'd just like to add that SE do have job openings which you can apply for.
You check them out by clicking the work here link in the footer of any of the Stack Exchange sites.
Since this is Ask Ubuntu, I thought I should also mention that you can also apply for a job at Canonical (The company behind Ubuntu). You can check those job opportunities by clicking the careers link in the footer of ubuntu.com.
